20 Super Sevens is a classic 5x3 reel slot with 20 paylines and 10 symbols. To win, players must match symbols on the paylines. The 7 is the WILD and substitutes for all symbols, except for Scatters. The 7 is the SCATTER, and Scatter wins are awarded when symbols appear randomly on any position on the reels and are added to line wins. The game comes with a GAMBLE FEATURE by which you can double or quadruple your winnings.
