Treat displayed values as version-specific
Record the app version and date whenever documenting a price or reward. Avoid promising a fixed amount based on an older screenshot.
Reward ads
Wait for the completion message before closing an advertisement. If the game does not grant the reward, capture the time and ad placement before restarting.
Best use of coins
Spend on a board that is already close to completion, not on repeated attempts with the same weak opening.
Purchases
Use only the in-game store and official storefront billing. Fish Sort Wiki never sells coins, accounts, or modified applications.
