Root Cause

The contract collects ether from losing players but does not provide a function for the contract owner to withdraw these accumulated funds.

Impact

• Locked Funds: Ether collected remains trapped within the contract indefinitely.

• Inefficient Capital Use: Accumulated funds cannot be utilized or reinvested by the owner.

• Potential Security Risk: The growing balance may attract attackers aiming to exploit any undiscovered vulnerabilities.

Recommendations

• Owner Withdrawal Function: Implement a secure function that allows the contract owner to withdraw excess funds.

• Access Control: Use access modifiers like onlyOwner to restrict this function to the contract owner.

• Event Emission: Emit events upon withdrawal for transparency and auditing purposes.
