The solution was:
1️⃣ Player chooses moves
2️⃣ Creates a commitment hash (moves + secret)
3️⃣ Submits only the hash on-chain
4️⃣ After all players commit, they reveal moves + secret
5️⃣ The contract verifies by hashing again & comparing
The secret prevents others from guessing moves

Implementing a commitment scheme with secret hashing ensures fair play and prevents manipulation in the game. Well thought out process outlined here for maintaining integrity in player interactions.
