Powered by Microgaming, the thrilling hotrod themed Supe It Up is a 5 reel, 25 payline and 250 coin slot machine. It offers a wild multiplier, a scatter, 11 regular symbols, a Free Spins bonus game, a Gamble bonus game and 37 winning combinations. Coin sizes range from $0.01 to $0.25, so the maximum bet is $62.50. The sound effects are top-notch and the graphics are gorgeous.

The Wild Nitrous symbol is a wild multiplier. It replaces any regular symbol to complete winning combinations and doubles the payout of a combination it completes. Five Wild Nitrous symbols on an enabled payline win the top jackpot of 10,000 coins x 10 coins per line = 100,000 coins in base game.

The Woofer symbol is a scatter. Scatter wins are obtained by multiplying the Woofer symbol combination payout by the total number of coins bet. Two, three, four or five Woofer symbols on the screen multiply the total coins bet by 2, 4, 20 or 600.

Three, four or five Woofer symbols scattered anywhere on the 5 reels activate the Free Spins bonus game during which all wins are multiplied 6 times. Any win on an enabled payline activates the Gamble bonus game during which the double-or-quadruple-or-nothing bonus can be played.
