Root Cause

The startGame function requires a minimum of 1 ether to start the game:

However, ether values can include more decimal places (wei), and a player might accidentally send slightly less than 1 ether due to miscalculations, leading to transaction failures.

Impact

• User Frustration: Players may experience failed transactions and lose gas fees.

• Reduced Participation: The high entry cost may discourage players from engaging with the game.

• Financial Loss: Repeated failed attempts can lead to unnecessary financial loss for players.

Recommendations

• Accept Smaller Bets: Allow players to start the game with smaller amounts of ether to encourage participation.

• User Interface Guidance: Provide clear instructions on the required amount of ether, possibly with exact values in wei.

• Graceful Handling: Consider implementing a more informative error message or a fallback mechanism for slight discrepancies in sent amounts.
