Lack of Mechanism for Handling Abandoned Games

Summary:


No function allows players to recover funds if both abandon the game without revealing moves.

Vulnerability Details:


No emergency escape or refund exists if both players timeout.

Code Snippet:

// No fallback or force refund mechanism after timeout
function revealMove(uint256 _gameId, uint8 _move, bytes32 _salt) external {
...
}

Tools Used:

Solidity

VS Code

Recommendations:

Add an abandonGame() function after double timeout expiry to allow safe fund recovery.
