Pick a template, change how it looks and feels, test it, then publish. A person plays every game before it goes on the hub. It gets its own page, board and share card, and every run on it is checked like a house game.
Continues bought inside your game are split 50% to you, paid in USDC to makers who are 18 or over with a linked wallet, once the store is switched on. Plays always count toward the makers' board.
