Root Cause

The contract does not limit the number of players who can join and start games. If many players start games simultaneously, it could lead to performance issues.

Impact

• Performance Degradation: The contract might experience slowdowns due to the high number of active games.

• Increased Gas Costs: Operations may become more expensive as the contract state grows.

• Potential Crashes: Extreme cases could lead to contract failure or inability to process new transactions.

Recommendations

• Player Limit: Introduce a maximum number of concurrent games or players.

• Resource Management: Optimize state management to handle multiple players efficiently.

• Scalability Testing: Conduct tests to determine the contract's capacity and adjust accordingly.
