+**hexo** is an educational game project — a clone of [DiceWars](https://www.gamedesign.jp/games/dicewars/).
 
 ### Game Concept
 
-A strategy dice game played on a hexagonal grid where players command armies of dice and battle to conquer territories.
+A strategy dice game played on a hexagonal grid where players command armies of dice and battle to conquer territories. The last player standing wins.
 
-### Core Game Mechanics
+### Features
 
-#### Map System
+- **2-4 Players**: Support for multiple human and/or AI players
-- Generatable hexagonal grid map (20x20 cells)
+- **Dynamic Map Sizes**: 10×10, 15×15, 20×20, 25×25 hexagonal grids
-- Each cell can be either playable or blocked/impassable
+- **AI Bots**: Computer-controlled players with smart move selection and thinking delay
-- Each field can hold up to 8 dice
+  - Makes multiple moves per turn until no valid moves remain
-- Each player-owned field provides +1 supply unit to the player
+  - Prioritizes favorable attacks, then expansion, then reinforcement
-
+  - 1000ms thinking delay between moves for natural gameplay
-#### Dice System
+- **Hexagonal Grid**: Proper axial coordinate system with 6-direction adjacency
-- Standard 6-sided dice
+- **Dice Combat**: Roll-based battle system with strength calculation
-- Unit strength calculation formula:
+- **Solid Territory Supply**: Supply = size of largest connected territory
-  ```
+- **Flexible Setup**: Any combination of human/AI players (hotseat, full AI, or mixed)
-  F = (cnt-1) * full_dice + current_dice
+- **88 Passing Tests**: Comprehensive test coverage for all game mechanics
-  ```
-  Where:
-  - `cnt` = number of dice on the field
-  - `full_dice` = maximum die value (6)
-  - `current_dice` = top die current value (1-6, calculated during gameplay)
-
-#### Game Rules
-1. **Setup**: Multiple dice are placed on the map for each player at the start
-2. **Movement Conditions**: A user can move a unit if its strength > 1
-   - When moving: strength-1 transfers to target cell, strength 1 remains on source cell
-3. **Combat**: When attacking a cell with enemy dice, both players roll:
-   - **Attacker**: `F_attack = rnd(F-1)` (random value less than original strength minus 1)
-   - **Defender**: `F_defence = current_strength` (full field strength)
-   - **Victory**: If `F_attack > F_defence`, attacker wins; otherwise defender repels the attack
-   - **On Victory**: Attacker leaves strength 1 on source cell, transfers `F_attack-1` to target
-   - **On Defeat**: Defender retains `F_defence - F_attack` (minimum 1)
-4. **Supply Phase**: After all players have moved, each receives supply:
-   - `S = sum(Cell)` where Cell = supply value from each player-owned cell
-   - Maximum per cell: `8 * full_dice` (48 dice points)
-   - If all cells already have maximum strength, no supply is added

 ## Technology Stack
 
-- **Runtime**: Node.js (inferred from jsdom usage)
+| Layer | Technology |
-- **Core Library**: [jsdom](https://github.com/jsdom/jsdom) - JavaScript implementation of DOM and HTML standards
+|-------|------------|
-  - Provides browser-like environment for server-side JavaScript
+| **Runtime** | Node.js |
-  - Enables DOM manipulation, event handling, and web API emulation
+| **Frontend** | Vanilla JavaScript (ES Modules), HTML5 Canvas, CSS3 |
-
+| **Backend** | Simple HTTP server (`server.js`) |
-## Development Status
+| **Testing** | Node.js built-in test runner (`node --test`) |
-
+| **Dependencies** | jsdom (local copy in `jsdom-pkg/`) |
-**Early Stage**: The project currently contains:
-- Game design documentation (README.md)
-- jsdom library setup (both local copy and node_modules installation)
-- No main game source files yet
 
 ## Building and Running
 
-> **TODO**: Build and run commands are not yet defined. The project is in initial setup phase.
-
-Expected setup once development begins:
 ```bash
-# Install dependencies
+# Start web server (http://localhost:8080)
-npm install
+npm run serve
 
-# Run the game (TBD)
+# Run console demo
 npm start
 
-# Run tests (TBD)
+# Run tests (88 tests)
 npm test
 ```
 
 ## Development Conventions
 
-> **TODO**: Coding standards and testing practices are not yet established.
+- **ES Modules** for browser code (`import`/`export`)
+- **CommonJS** for Node.js code (`require`/`module.exports`)
+- **Dual exports** in `map.js` for both ES and CommonJS compatibility
+- **Tests** use Node.js built-in `node:test` module
 
-### Inferred Practices (based on jsdom usage)
+## Core Game Mechanics
-- JavaScript/TypeScript expected for implementation
+
-- DOM-based rendering likely planned (given jsdom inclusion)
+### Map System
-- Game logic will need to implement:
+
-  - Hexagonal grid generation
+The map system supports **dynamic sizes** (10×10, 15×15, 20×20, 25×25):
-  - Dice mechanics and randomization
+
-  - Turn-based combat system
+```javascript
-  - Player state management
+// Create map with custom size
+const map = new HexMap(15);  // 15x15 grid
+
+// Default size is 20x20
+const defaultMap = new HexMap();
+```
+
+**Key characteristics:**
+- Hexagonal grid using **axial coordinates** (q, r)
+- Each cell can be passable or blocked/impassable (~15% blocked)
+- Each cell can hold up to **8 dice**
+- Cells connect to **6 neighbors** (hexagonal adjacency)
+- Neighbor calculation respects map boundaries
+
+### Dice System
+
+- Standard 6-sided dice
+- **Unit strength calculation formula:**
+  ```
+  F = (cnt - 1) × 6 + current_dice
+  ```
+  Where:
+  - `cnt` = number of dice on the cell
+  - `current_dice` = top die value (1-6)
+
+**Examples:**
+| Dice Array | Calculation | Strength |
+|------------|-------------|----------|
+| `[4]` | (1-1)×6 + 4 | 4 |
+| `[6]` | (1-1)×6 + 6 | 6 |
+| `[6, 1]` | (2-1)×6 + 1 | 7 |
+| `[6, 6, 2]` | (3-1)×6 + 2 | 14 |
+| `[6, 6, 6, 6, 6, 6, 6, 6]` | (8-1)×6 + 6 | 48 (max) |
+
+### Game Rules
+
+1. **Setup**: Each player starts with strength 8 at their starting position
+2. **Movement**: Can move if strength > 1
+   - Source cell left with 1, target receives strength-1
+3. **Combat**: Both sides roll dice (1 to their strength)
+   - **Attacker wins**: Takes cell with `attack_roll - 1`, source becomes 1
+   - **Defender wins**: Attacker reduced to 1, defender keeps `defense_roll - attack_roll` (min 1)
+4. **Supply**: After turn ends, player receives supply = largest connected territory size
+   - Distributed 1 by 1 to random non-max cells
+   - Max per cell: 48 (8 dice × 6)
+5. **Victory**: Last player with cells on the map wins
+
+### Player Configuration
+
+| Player | Color | HEX Code | Starting Position |
+|--------|-------|----------|-------------------|
+| P1 | 🟢 Green | `#4ecca3` | (offset, offset) |
+| P2 | 🔴 Red | `#e94560` | (size-1-offset, size-1-offset) |
+| P3 | 🟡 Yellow | `#f9ed69` | (offset, size-1-offset) |
+| P4 | 🔵 Cyan | `#00adb5` | (size-1-offset, offset) |
+
+Where `offset = max(1, floor(mapSize / 10))`
+
+Each player starts with **strength 8** at their starting position.
+
+### Starting Positions by Map Size
+
+| Map Size | Offset | P1 | P2 | P3 | P4 |
+|----------|--------|----|----|----|----|
+| 10×10 | 1 | (1,1) | (8,8) | (1,8) | (8,1) |
+| 15×15 | 1 | (1,1) | (13,13) | (1,13) | (13,1) |
+| 20×20 | 2 | (2,2) | (17,17) | (2,17) | (17,2) |
+| 25×25 | 2 | (2,2) | (22,22) | (2,22) | (22,2) |
+
+## AI Bot Logic
+
+### Implementation Details (`ai-bot.js`)
+
+The AI bot is implemented in the `AIBot` class with the following behavior:
+
+#### Multiple Moves Per Turn
+
+Unlike a simple single-move AI, this bot makes **multiple moves per turn**:
+
+```javascript
+async playTurn() {
+  let moveCount = 0;
+  const maxMovesPerTurn = 50;  // Prevent infinite loops
+  const maxConsecutiveNoMoves = 3;
+
+  while (consecutiveNoMoves < maxConsecutiveNoMoves && moveCount < maxMovesPerTurn) {
+    const moves = this.findPossibleMoves(playerCells);
+    
+    if (moves.length === 0) {
+      consecutiveNoMoves++;
+      continue;
+    }
+
+    consecutiveNoMoves = 0;
+    moves.sort((a, b) => this.movePriority(b) - this.movePriority(a));
+    
+    await this.wait(this.thinkingTime);  // 1000ms delay
+    
+    this.executeMove(moves[0]);
+    moveCount++;
+  }
+
+  this.gameUI.endTurn();
+}
+```
+
+#### Thinking Delay
+
+- **Delay**: 1000ms between moves
+- **Purpose**: Creates natural gameplay feel, allows human players to follow AI actions
+
+#### Move Evaluation
+
+The AI evaluates all possible moves using a priority system:
+
+```javascript
+movePriority(move) {
+  let priority = 0;
+
+  // Attack weak enemies (highest priority)
+  if (move.type === 'attack') {
+    if (move.attackStrength > move.defenseStrength) {
+      priority += 100; // Likely to win
+      priority += move.attackStrength - move.defenseStrength;
+    } else {
+      priority -= 50; // Risky attack
+    }
+  }
+
+  // Expand to empty cells (medium priority)
+  if (move.type === 'expand') {
+    priority += 50;
+    priority += move.attackStrength; // Stronger placement = better
+  }
+
+  // Prefer moves that create strong positions
+  priority += move.attackStrength * 0.5;
+
+  return priority;
+}
+```
+
+#### Move Types and Priorities
+
+| Type | Condition | Priority | Description |
+|------|-----------|----------|-------------|
+| **Attack (favorable)** | attack > defense | 100+ | Attack enemy with higher strength |
+| **Expand** | empty cell | 50+ | Capture empty cells |
+| **Attack (risky)** | attack ≤ defense | -50 | Attack enemy with equal/higher strength |
+
+#### Turn Flow
+
+1. Get all player cells
+2. Find all possible moves (neighbors that are not own cells)
+3. Sort moves by priority
+4. Wait for thinking delay (1000ms)
+5. Execute best move
+6. Repeat until no moves available (max 50 moves per turn)
+7. End turn
+
+### Integration with Game UI
+
+The AI bot integrates with the main game through:
+
+- **`gameUI.selectedCell`** / **`gameUI.currentTarget`**: Set before executing moves
+- **`gameUI.executeAttack()`**: Called to perform the actual attack
+- **`gameUI.endTurn()`**: Called when AI has no more moves
+- **`gameUI.isAIThinking`**: Flag to prevent user interaction during AI turn
 
 ## Key Implementation Areas
 
-When development begins, focus on these components:
+### 1. Map Generator (`map.js`)
 
-1. **Map Generator**: Hexagonal grid creation with passable/impassable cells
+```javascript
-2. **Dice Engine**: Randomization and strength calculation
+class HexMap {
-3. **Combat System**: Attack/defense resolution logic
+  constructor(size = 20) {
-4. **Game State**: Player turns, unit positions, victory conditions
+    this.size = size;
-5. **UI/Rendering**: Visual representation of the game board
+    this.cells = new Map();  // Key: "q,r", Value: HexCell
+    this.generate();
+  }
+
+  generate() {
+    for (let q = 0; q < this.size; q++) {
+      for (let r = 0; r < this.size; r++) {
+        const type = Math.random() < 0.15 ? CELL_TYPES.BLOCKED : CELL_TYPES.EMPTY;
+        this.cells.set(`${q},${r}`, new HexCell(q, r, type));
+      }
+    }
+  }
+}
+```
+
+**Features:**
+- Hexagonal grid creation with passable/impassable cells
+- Cell ownership tracking
+- Neighbor calculation (6 directions)
+- Supply calculation (largest connected territory via BFS)
+
+### 2. Dice Engine (`game.js`)
+
+```javascript
+// Strength calculation
+getStrength() {
+  if (this.dice.length === 0) return 0;
+  const cnt = this.dice.length;
+  const currentDice = this.dice[this.dice.length - 1];
+  return (cnt - 1) * 6 + currentDice;
+}
+
+// Set strength (reconstruct dice array)
+setStrength(targetStrength) {
+  if (targetStrength <= 0) {
+    this.dice = [];
+    return;
+  }
+  const cnt = Math.floor((targetStrength - 1) / 6) + 1;
+  const remainder = targetStrength - (cnt - 1) * 6;
+  this.dice = new Array(cnt - 1).fill(6);
+  if (remainder > 0) this.dice.push(remainder);
+}
+```
+
+### 3. Combat System (`game.js`)
+
+```javascript
+executeAttack() {
+  const attackStrength = attacker.getStrength() - 1;
+  const defenseStrength = defender.getStrength();
+
+  const attackRoll = Math.floor(Math.random() * attackStrength) + 1;
+  const defenseRoll = Math.floor(Math.random() * defenseStrength) + 1;
+
+  if (attackRoll > defenseRoll) {
+    // Attacker wins
+    defender.setStrength(attackRoll - 1);
+    this.map.setOwner(defender.q, defender.r, this.currentPlayer);
+  } else {
+    // Defender wins
+    defender.setStrength(Math.max(1, defenseRoll - attackRoll));
+  }
+  attacker.setStrength(1);
+}
+```
+
+### 4. Game State (`game.js`)
+
+- **Player turns management**: Circular turn order (P1 → P2 → P3 → P4 → P1)
+- **Unit positions tracking**: Via `HexMap` cell ownership
+- **Victory conditions**: Last player standing (checked when player loses all cells)
+- **AI turn handling**: Async/await pattern for sequential AI moves
+
+### 5. UI/Rendering (`game.js`)
+
+```javascript
+class GameUI {
+  constructor() {
+    this.canvas = document.getElementById('game-canvas');
+    this.ctx = this.canvas.getContext('2d');
+    this.mapSize = 20;  // Dynamic, configurable
+    this.playerCount = 2;  // 2-4 players
+    this.playerTypes = {};  // {1: 'human', 2: 'ai', ...}
+  }
+
+  // Hex to pixel conversion for rendering
+  hexToPixel(q, r) {
+    const sqrt3 = Math.sqrt(3);
+    const x = this.offsetX + HEX_SIZE * sqrt3 * (q + r/2);
+    const y = this.offsetY + HEX_SIZE * 1.5 * r;
+    return { x, y };
+  }
+}
+```
+
+**Features:**
+- HTML5 Canvas rendering
+- Hexagon drawing with proper coordinates
+- Player color indicators
+- Dice visualization (strength + die count dots)
+- Battle log
+
+### 6. AI Bot (`ai-bot.js`)
+
+**Key features:**
+- Move evaluation and prioritization
+- Thinking delay for natural gameplay
+- Multiple moves per turn
+- Integration with game UI for move execution
+- Boundary and blocked cell awareness

 ## Notes
 
 - The `.gitignore` file appears to be a Python template and may need to be updated for a JavaScript project
 - The `jsdom-pkg` directory contains a local copy of jsdom, possibly for offline development or custom modifications
 - Game rules are documented in Russian in README.md
+- All game logic runs in the browser (no server-side game state)
+- The project uses **no `src/` directory** — all source files are in `public/`

-3. правила игры
+## Экран запуска
-    1. вначале на карты помещается несколько кубиков для каждых игроков
+
-    2. юзер может ходить юнитом, если
+При запуске игры открывается экран настройки:
-        1. его сила больше 1, при этом на захваченную клетку перемещается сила-1, а на исходной остается кубик с силой 1
+
-        2. если на захватываемой клетке вражеские кубики, то оба игрока бросают кости
+1. **Выберите количество игроков**: 2, 3 или 4
-            1. у нападающего количество максимальной силыменьше на 1 исходной, F_attac=rnd(F-1)
+2. **Выберите размер карты**:
-            2. у защищающегося полная сила поля, F_defence=ктв(F)
+   - **Small (10×10)** — Быстрая игра на маленькой карте
-            3. 
+   - **Medium (15×15)** — Сбалансированный размер
-            4. условия победы
+   - **Large (20×20)** — Стандартный размер (по умолчанию)
-                1. если F_attac>F_defence - то победа нападающего иначе защищающийся отбил атаку
+   - **Extra Large (25×25)** — Большая карта для длительных игр
-                2. при победе нападающего он оставляет на исходной клетке кубик с силой 1, на захватываемую переводит F_attac-1, 
+3. **Настройте тип каждого игрока**:
-                3. при пройгрыше у защищающегося отсается F_defence-F_attac, но не меньше 1
+   - **Human** — управление человеком (клики мышью)
-    3. После того, как все игроки походили, каждый получает снабжение по формуле 
+   - **AI Bot** — управление компьютером
-        S=sum(Cell), где Cell - значение снабжения с каждой клетки, принадлежащей игроку
+4. Нажмите **Start Game** для начала игры
-        1. Саксимальное кол-во на клетке может быть 8*Full_dice
+
-        2. Если все клетки игрока имеют максимальное колво силы, то ничего не добавляется.
+### Комбинации игроков
-            
+
-            
+Можно создавать любые комбинации:
+- Все игроки — люди (Hotseat)
+- Все игроки — AI боты (наблюдение за игрой ИИ)
+- Смешанный режим (например, P1-Human, P2-AI, P3-Human, P4-AI)
+
+## Цвета игроков
+
+| Игрок | Цвет | HEX |
+|-------|------|-----|
+| P1 | 🟢 Зелёный | `#4ecca3` |
+| P2 | 🔴 Красный | `#e94560` |
+| P3 | 🟡 Жёлтый | `#f9ed69` |
+| P4 | 🔵 Бирюзовый | `#00adb5` |
+
+## AI Bot
+
+### Как работает
+
+AI бот автоматически играет за выбранного игрока:
+
+1. **Анализ поля** — бот оценивает все возможные ходы
+2. **Приоритеты ходов**:
+   - 🎯 Атака слабого противника (высокий шанс победы) — приоритет 100+
+   - 📈 Захват пустых клеток (расширение территории) — приоритет 50+
+   - 💪 Укрепление позиций (перемещение к сильным клеткам)
+3. **Задержка мышления** — 1000 мс перед каждым ходом для естественности геймплея
+4. **Несколько ходов за turn** — AI делает все возможные ходы подряд, затем завершает ход
+
+### Индикаторы AI
+
+- В карточке игрока отображается метка **(AI)**
+- Во время хода AI в панели действий показано: *"AI is thinking..."*
+- Кнопки управления отключены во время хода AI
+
+### Логика принятия решений
+
+```javascript
+movePriority(move) {
+  let priority = 0;
+

+
+## Правила игры
+
+### 1. Карта
+
+- Гексагональная сетка **10×10**, **15×15**, **20×20** или **25×25** ячеек
+- Каждая ячейка может быть:
+  - **Проходима** (пустая или принадлежит игроку)
+  - **Непроходима** (заблокирована, серый цвет, ~15% карты)
+
+### 2. Игровые единицы
+
+- **Кубик**: 6-гранный, значения 1-6
+- На поле может быть до **8 кубиков** на клетку
+- **Сила юнита**: `F = (cnt-1) × 6 + current_dice`
+  - `cnt` — количество кубиков
+  - `current_dice` — значение верхнего кубика
+
+**Примеры расчёта силы:**
+| Кубики | Сила |
+|--------|------|
+| [4] | 4 |
+| [6] | 6 |
+| [6, 1] | 7 |
+| [6, 6, 2] | 14 |
+| [6, 6, 6, 6, 6, 6, 6, 6] | 48 (максимум) |
+
+### 3. Ход игры
+
+#### Перемещение/Атака
+
+- Можно ходить, если **сила > 1**
+- На целевую клетку переходит `сила-1`, на исходной остаётся **1**
+- При атаке оба игрока бросают кости:
+  - **Атакующий**: `attack_roll = rnd(1..сила-1)`
+  - **Защищающийся**: `defense_roll = rnd(1..сила)`
+
+#### Результат боя
+
+| Условие | Результат |
+|---------|-----------|
+| `attack_roll > defense_roll` | Атакующий побеждает, занимает клетку с `attack_roll-1`. На исходной клетке остаётся **1** |
+| `attack_roll <= defense_roll` | Атака отбита. Атакующий уменьшается до **1**. Защитник остаётся с `defense_roll - attack_roll` (мин. **1**) |
+
+#### Снабжение
+
+После хода игрок получает снабжение:
+
+- **Снабжение = размер наибольшей непрерывной территории**
+- **Непрерывная территория** — связанные между собой клетки игрока
+- Если территория разорвана врагом — считается только наибольший кусок
+- Снабжение распределяется по **1 единице** случайным клеткам (не максимальным)
+- **Максимум на клетке**: 48 (8 кубиков × 6)
+
+### 4. Победа
+
+**Последний игрок**, оставшийся с клетками на карте, побеждает.
+
+## Управление
+
+| Действие | Управление |
+|----------|------------|
+| Выбрать клетку | Клик на свою клетку с кубиками |
+| Атаковать | Клик на соседнюю вражескую/пустую клетку |
+| Отменить выбор | Кнопка **Cancel** или клик на ту же клетку |
+| Завершить ход | Кнопка **End Turn** |
+| Вернуться в меню | Кнопка **Main Menu** |
+
+### Индикаторы на экране
+
+- **Выделенная клетка** — красная подсветка
+- **Доступные цели** — зелёная подсветка соседних клеток
+- **Лог боёв** — правая панель с историей действий
+- **Инфо о клетке** — сила и количество кубиков выбранной клетки
+
+## Настройки игры
+
+Игра поддерживает:
+- **2-4 игрока** (любая комбинация людей и AI)
+- **4 размера карты**: 10×10, 15×15, 20×20, 25×25
+- **Случайная генерация карты** при каждом запуске
+- **Случайные стартовые позиции** для игроков
+
+## Стартовые позиции
+
+Игроки размещаются в углах карты (позиции масштабируются с размером карты):
+
+| Игрок | Позиция | Описание |
+|-------|---------|----------|
+| P1 | (offset, offset) | Верхний-левый угол |
+| P2 | (size-1-offset, size-1-offset) | Нижний-правый угол |
+| P3 | (offset, size-1-offset) | Нижний-левый угол |
+| P4 | (size-1-offset, offset) | Верхний-правый угол |
+
+`offset = max(1, floor(size / 10))`
+
+Каждый игрок начинает с **силой 8** на своей стартовой позиции.
+
+## Тестирование
+
+Проект покрыт **88 тестами**, проверяющими:
+
+- **Динамические размеры карт** (10×10, 15×15, 20×20, 25×25)
+- **HexCell**: создание, расчёт силы, максимальная сила, добавление кубиков
+- **HexMap**: генерация, соседи, снабжение, владение
+- **Логика выбора целей**: атака врагов, захват пустых клеток, блокировка своих клеток
+- **AIBot**: поиск ходов, приоритеты, выполнение ходов, завершение хода
+- **Интеграционные тесты**: 4 AI бота одновременно, разные размеры карт
+
+```bash
+npm test
+```
+
+Все тесты проходят успешно ✅
