How to Play

Master the Diamond Challenge in minutes

Game Rules

1

Players take turns clicking on lines between diamond cells on the board.

2

When you complete all edges around a diamond cell, you capture it — your symbol appears inside.

3

If you capture a cell, you do NOT get an extra turn (unlike classic Dots & Boxes).

4

The player with the most captured cells when all edges are taken wins!

⏱ Turn Timer

Each player (and the AI) has 5 seconds per turn. If time runs out, the turn passes automatically to the next player — no random move is placed. Stay focused!

🤖 Gemini AI Opponent

The AI opponent is powered by Google's Gemini AI and thinks about the best strategic moves. The AI also has a 5-second timer — if it doesn't respond in time, its turn is skipped and you play again.

Strategy Tips

Avoid completing 3 edges of a cell — your opponent can finish it next turn.
Look for chains of cells where completing one leads to capturing many.
Control the corners and edges first to create favorable chain opportunities.
Sacrifice a few cells to break an opponent's chain.
