GateCrash

A small parimutuel game built with the same parts as the machine. Four chambers, one detonates every 99 seconds.

GateCrash is a game on BNB Chain, built by the same design house and on the same parts as Series 01. It does not mint a new asset and does not promise a yield. It gives the cards a second job.

How a round works

A round runs 99 seconds. Players back one of four chambers: CORE, FLIP, OVERLOAD or BREACH. When the window closes the round locks; two blocks later anyone can draw. One chamber detonates, the survivors split the whole pool by stake.

seedBlock  = lockBlock + 2
seed       = keccak256(abi.encodePacked(blockhash(seedBlock), roundId))
deadRoom   = uint256(seed) % 4 + 1

winning    = pool - pool[deadRoom]
gross      = yourStake * pool / winning
fee        = gross * 500 / 10000
payout     = gross - fee

The seed only uses values fixed at lock time: the block hash of the seed block and the round id. It does not use the timestamp or the coinbase, so the operator cannot pick a result by choosing when to submit. The draw is permissionless.

Bets

BEM is the default token and BNB is accepted as well. Each token has its own pool and pays out in itself. Minimums are 0.02 BEM and 0.0008 BNB, both close to $0.50. A wallet can back more than one chamber; each chamber is settled separately against the same draw.

Fees

A fee is taken when a winner claims: 2.5% for circuit card holders, 3% for wallets holding 100 BEM, 5% for everyone else. Of the fee, 90% is allocated to ecosystem users and 10% to the foundation. The split is executed by the team under rules published with the game; the contract only forwards the fee to the treasury wallet.

Why it belongs to the cards

The game is a recurring demand sink for the same circuits the foundry sells: every round is played in BEM and every fee flows back to the people holding the cards. It is not mining, not a claim on BEM and not a financial product.
