Win what you see. The three numbers read left→right are your win (e.g. 10 · 5 · 00 = 10,500). A lone 0 is no win — but any 0s showing HOLD and the other reels respin to try to make a number (and can chain). After a win, the last reel may respin once to upgrade — never down. Wins scale with your bet (exact at bet 10).
