Summary

The createGameWithEth function uses block.timestamp to set creationTime and joinDeadline. While this is standard practice, miners can manipulate timestamps within a small range, potentially affecting game timing.

Vulnerability Details

A miner-controlled player (Player A) can slightly manipulate block.timestamp (within ~15 seconds) to extend or reduce the join deadline window.

Impact

Minor timing inconsistency. Not exploitable for major economic gain, but may affect fairness in edge cases.

Tools Used

Manual review.

Recommendations

Use block.timestamp with caution. For time-sensitive logic:

• Document potential for slight manipulation.

• Consider block.number for more consistency (less precise, but more stable over time).
