Your Tama won't play games if it is too lightweight.
Try to feed it some snacks - then see if it will play a game.
If you play slots and bet 9p, you don't always get 900p - only if you win (thats 3 x Os in a row).
If you don't get all 3 x Os, then you win lower amounts of points - 72p, 250p, 450p (or something similar to that amount...). That's still quite alot of points, so it is worth trying to win with 9points !
Best, etc.
