Game Constraints

One Bet at a Time

You cannot place a new bet while a previous bet is pending resolution. This prevents potential exploits and ensures fair play.

Access Control

Players must hold a LAZER whitelist token to participate. This token serves as an access pass to the game.

Pausing

The game owner can pause the contract in emergencies. While paused, no new bets can be placed, but pending bets will still be resolved.

Fair Play Guarantees

• No manipulation: Random numbers come from Chainlink VRF

• Transparent: All game logic is on-chain and verifiable

• Automatic: Payouts are processed by the smart contract

• Auditable: Every bet and result is recorded on the blockchain
