Verification Method

1. Commitment Hash

keccak256(gameId + gameSeed + normalizedShipLayout + salt)

2. Shot Assignment

initialSquare = keccak256(txHash + gameSeed + gameId) mod 1000 + 1

3. Collision Resolution

Linear probe: if square occupied, try next (wrap 1000 → 1)

4. Hit Detection

Check if assigned square is in ship positions
