Bulls Eye has two phases. ## Phase 1: bonding builds the vault * The Flap launch bonds first * Buy tax and sell tax keep feeding the vault * The pot can grow before the jackpot goes live * No buy alerts fire yet because the game is not armed ## Phase 2: migration arms the jackpot 1. The pair migrates. 2. The jackpot is armed. 3. Buys of at least `0.01 ETH` worth of `BEYE` qualify for a shot. 4. The buy size sets the odds. 5. Chainlink VRF resolves the draw. 6. If the buy wins, `ETH` is sent straight to the buying wallet. ## What counts as a shot * Only buys can trigger the jackpot * Sells still pay tax but do not get a draw * The floor starts at `0.01 ETH` ## Why the pot does not die on one hit * The public jackpot is always `50%` of the available vault * Half stays behind after every hit * That keeps the game alive instead of going dead after one winner ## Buy size matters Bulls Eye buy odds banner | Buy amount | Chance to win | | ----------: | ------------: | | `0.01 ETH` | `0.10%` | | `0.05 ETH` | `0.50%` | | `0.10 ETH` | `1.00%` | | `0.25 ETH` | `2.50%` | | `0.50 ETH` | `5.00%` | | `0.75 ETH` | `7.50%` | | `1.00 ETH+` | `10.00%` max | * Buys below `0.01 ETH` do not get a draw * Odds scale with the native ETH value of the buy, not the number of tokens received * Anything above `1 ETH` stays capped at `10%`
