The main source of Coins in 8 Ball Champions is from winning Tour Matches. Winning the match rewards you with the combined entry fee from you and your opponent and a Prize Case (as long as there is an available case slot in the Main Menu).

Coins can also be earned from opening Cases, playing Minigames, and as prizes collected from the XP Road, Season Pass, and Events.

The Free Case on the Main Menu and the Free Watch Ad button are further sources for coins. The Free Case refreshes every 4 hours. The Free Watch Ad button refreshes every 3 hours and has a chance of winning coins or other items.

You can purchase Coin packs from the Store Menu in exchange for Gems to get even more Coins.
