★ GAMEPLAY FEATURES

━━━━━━━━━━━━━━━━━━━━━━━

⚔ Three AI Difficulty Levels

• Easy — relaxed, random-weighted AI for casual play

• Medium — heuristic AI that advances, prefers kings and captures

• Hard — depth-4 minimax with alpha-beta pruning. It will challenge you.

⏱ Turn Timer

Each turn runs a 30-second countdown. The animated ring counts down with tick sounds at the final 5 seconds. Run out of time and the game plays a move for you automatically.

↩ Undo System

Made a mistake? Undo up to your last 10 moves with full board-state restoration. Each undo is tracked — can you win without using it?

💡 Hint System

3 hints per game. The AI evaluates the board position and marks the best available move with a star. Use them wisely.

🎯 Threat Detection

Red-tinted squares show you which of your pieces the AI can capture on its next turn — real tactical awareness built into the board.

★ HOW TO PLAY

━━━━━━━━━━━━━━━━━━━━━━━

You are Red. The AI plays Black. Pieces move diagonally on dark squares. Capture enemy pieces by jumping over them. If a capture is available, it is mandatory. Chain multiple captures in a single turn. Reach the opposite end of the board to crown a King — Kings move in all four diagonal directions. Capture all your opponent's pieces or block them from moving to win.
