Grid survival game with real-time tile elimination
Step-by-Step Guide
- 1
Choose your grid size: 5×5 (25 tiles), 6×6 (36 tiles), or 7×7 (49 tiles).
- 2
Select 1–5 tiles as your safe zones. These are the tiles you need to survive.
- 3
Set your bet and start the game.
- 4
Tiles begin going dark one by one in a provably fair random order. Your multiplier climbs with each survival.
- 5
Cash out at any time to lock in your multiplier, or wait for bigger payouts. If your tile goes dark, you lose.
Provably Fair System
The entire elimination order is a Fisher-Yates shuffle of all tile indices, seeded by HMAC-SHA256(server_seed, client_seed:nonce). The shuffle determines the exact order tiles go dark — but they're revealed one at a time. You can verify the full order after rotating seeds.
Visit the Fairness Verification page to verify any past round with your seeds.
