Seven 7’s Bonus Features

The theming of this slot is something that melds together old school slots and new school design and brings to mind the slot machines of the past, as does the use of symbols like the 7 and the Bar. The animation itself is smooth and beautiful, giving you that classic feel all while being totally up to date.

Looking at all the main Seven 7’s bonus features, it’s quite a unique game. When you trigger a respin, the first reel will lock and you’ll get more reels as you spin. This is what’s going to get you the big wins.


There’s an x2 Wild Multiplier symbol in the Seven 7’s slot, which helps multiply your winnings. Beware that you can only get this symbol on reels 2 to 6. They act as a 7, and it will double the payout of your win. However, it will not double the value of the top jackpot if you get that far.

Free Spins

The gameplay of the Seven 7’s game hinges on the free spins feature. Seven 7’s free spins trigger when you get a 7 on reel one. That reel will then lock, and then a new reel will appear and spin. If you get a 7 or an x2 Wild, it will bring up another reel, going on until there are 7 reels on the board.

Seven 7’s Jackpot

Seven 7’s jackpot is a big one – £250,000 – making it a potential big winner for you. The maximum payout on a single spins works out at 25,000x your stake if you play with a max bet.

RTP and Volatility

Seven 7’s RTP is fixed at 96.60%, making it slightly lower than other slots but still a pretty good return to player figure. Seven 7’s volatility is high, which is a given with such a large payout. You’ll win around one in five times on the Seven 7’s slot game, making it riskier but more rewarding.

Seven 7’s Bonus Spins

As a fairly high variance slot, you’ll want to play for fun first with some casino bonuses. Therefore check if you can get hold of some Seven 7’s bonus spins at UK casinos. These spins will let you play the game for free. Casumo, Spinit and Casino Gods often offer a good welcome deal to their new players so be sure to check it out.

Seven 7’s on Mobile

Released by Crazy Tooth Studio & Microgaming, Seven 7’s got to be optimised for mobile casinos, and it is. It works great on most mobile phones making it so much easier to play a few spins, wherever you are.
