Game overview
What is Big Win 777?
Match any two identical lucky 7 symbols or three identical bar symbols across the slot’s 15 paylines to pick up a win in the main game…it’s as simple as that. The sparkling Diamond Wild will substitute for any symbol (excluding the Scatter) to help you create winning combinations. But, that’s not all. The Chance Wheel Scatter will appear on the first, third and fifth reels of the game and, if you land three in one spin, it will activate the Chance Wheel. Once activated, a giant “wheel of fortune” will appear, click on it to give it a spin! The wheel offers you a whole host of rewards including free spins or instant prizes including up to 777x your bet. The Chance Wheel also gives you the opportunity to enter Big Win Free Spins. If you win free spins through the Chance Wheel, then you’ll enter Big Win Free Spins mode, where you’ll be rewarded with 12 free spins. During Big Win Free Spins, any Chance Wheels you land will award you more spins or the opportunity to spin the Chance Wheel again. One Scatter equals one extra spin, two Scatters equals two extra spins, and three Scatters will activate the Chance Wheel. During free spins the Chance Wheel will give you the possibility of winning +5, +10 or +20 extra free spins! Still not enough? Well how about the fact that Wilds will stick to the reels during free spins and, for each spin after they’ve landed, they’ll duplicate themselves up or down the reels to help you the paylines! Once they reach the top or bottom of the reel, they’ll disappear. As well as Chance Wheel and Big Win Free Spins, Big Win 777 also includes two more great features; Booster Spins and Gamble. During the main game, Booster Spin could activate at any time, slowing down reels 1, 3 and 5 and guaranteeing you at least two Scatters for that spin! Gamble is the classic feature that lets you multiply your winnings by guessing the colour or suit of a card correctly. After every win in the main game, if you can guess the colour you’ll DOUBLE your winnings, if you can guess the suit, your winnings will QUADRUPLE. Are you ready to take a chance and win big? Then play Big Win 777!
