Gobo invited you to play his card game. It sounded fun, but you always have to remember; The house ALWAYS wins!
Type how many rounds you passed in the comments! Place cards to get the black number above the required score. Multiplier cards increase the round multiplier which makes all future cards played in that round worth more. You eventually will unlock upgrades and items, which tells you what they do. If your score is below the required score and you’re out of cards you lose!
