# Lotto Round & Winners Protection

Celestium's lotto-style dynamic games guarantee that a winning bet will be paid — even before the round has spun. The protection works by reserving the maximum potential payout from the dynamic staking pool at the moment the bet is accepted, rather than after the result is known.

## Round Process

1. The contract checks that the dynamic staking pool holds enough CELT to cover the worst-case payout of the incoming bet. If the reserves are insufficient, the bet is rejected.
2. The fairness check passes — the bet is recorded against the round.
3. At the spin, the maximum potential payout for that bet is **transferred into a dedicated protection pool**. The funds are moved out of the general staking balance and earmarked for the bet specifically.
4. The result is generated by Chainlink VRF and the round resolves.

The effect is that winning bets are paid from funds that were already set aside for them — the user can be 100% sure that the winning is protected, regardless of what happens to the rest of the pool between bet placement and round resolution.

## Dynamic Games Result Execution

* **Losing bets** — the entire bet amount flows from the protection pool into the dynamic staking pool. This is the pool's revenue from the round.
* **Winning bets** — the contract transfers the protected payout directly to the winner's wallet in the same transaction as the resolution.
