Thirteen Bonus Features

Along with the frightfully fun free spins available in Thirteen, its double-or-nothing bonus feature will make your hair stand on end. Each time you win, you’ll have the opportunity to double your bet by guessing the colour, either black or red, of a flipped card. Each time you correctly choose the winning colour, you can double your winnings again. You can continue doubling your credits until you decide incorrectly or elect to collect your bounty.

Thirteen Free Spins

Black cats crossing your path is actually good luck in the Thirteen slot machine. Land three to five black cat scatter symbols and receive 13 free spins. As you use your free spins, you’ll receive one additional free spin each time the black cat scatter symbol lands on your screen. As a frightfully exciting feature in the slot game, wild witch symbols will stay locked each time they land, until they’re used for a winning payout. Extra free spins and high-value locked wild symbols mean your cauldron could overflow with winnings.

Thirteen Winning Symbols

Just as the name implies, Thirteen features 13 winning symbols. Seven symbols are themed for a hauntingly good time; the most valuable of which is the wild witch. Not only will she act as a substitute for any symbol except the black cat, but she will also garner the highest reward. Land five wild witches across a single pay line, and you’ll receive 1,000 times your bet. Win back your bet with just two wild witches. You’ll be eager to see the witches and the black cat scatter symbol. The scatter bonus not only pays up to 500 times your bet, but landing at least three will also earn you 13 free spins.

Thirteen continues to brew up the fun with additional themed symbols. Gaze into the crystal ball symbol to find your fortune or see your winnings reflected in the mirror on the wall symbol. Be surprised at the opportunities through the door number 13 symbol or find out your future with the tarot card symbol. Thirteen will keep you on pins and needles with the voodoo doll symbol.

The final six symbols are the classic A, K, Q, J, 10, and 9. Though the lowest in value, landing at least five will win you 10 times your bet.
