Chance Machine 20 by Endorphina is a video slot built around a 5-reel, 3-row grid with 20 fixed paylines. The game uses a classic casino style with polished symbols, including 7s, bells, clovers, BARs, card suits, and a Scatter star. The stated RTP is 96%, and the bet range runs from 0.2 to 40.
The Wild symbol appears on reels 2, 3, and 4, where it can expand vertically and substitute for all symbols except Scatter. Scatters pay on their own and are listed separately in the paytable, while the top symbol values are shown for five-of-a-kind combinations. The control panel also includes Turbo, Auto, and a large Spin button.
A demo version is available to play for free, which lets users review the mechanics and practice before playing for real money. After a win, the Gamble feature may appear, giving the option to take the payout or try to increase it on a card-style screen.
