Seven 7s Slot Review

The developer Crazy Tooth Studio seems to have a soft spot for innovations. The studio isn’t afraid to experiment and plans to release Seven 7s for the 18th of February 2020. The slot is unconventional and fresh, unlike any other that you have played before. You can expect high volatility, expanding grid with one reel at a time on a winning spin. Also, wild multipliers will ensure you great fun and lucrative rounds.

About Seven 7s Slot

This is a unique game with only one pay-line, innovative rules and features. At the start, there is also only one reel with one giant symbol. If you this is 7 on the pay-line you add a new spinning reel to the grid. If you are lucky enough to land another 7 or 2x symbol, which is the wild multiplier, you continue to add reels. You will get an x2 boost of your payout. This way you can expand the grid to contain up to 7 reels in total.

The game will reset to 1 reel at the beginning of a new paid spin. All respins following a winning symbol are free. In the game, there are 3 symbols. These are the 7, the 2x wild multiplier and the BAR, which doesn’t pay. The game uses Continuwin™ mechanics. It expands reels upon hitting a win and triggers a free respin.

Players can choose wagers from 0.20 to 10 credits per spin. The slot has high volatility and an RTP of 96.6%. The jackpot is 25,000 times your stake and you win it when you land 7 sevens. This can grant you £250,000 when playing with the highest stake.

Seven 7s Design

The game is intricately designed with a lot of ornaments in brown, yellow and green around the reel/reels. Over them, you will see displayed the pay-table. It increases revealing more on each winning spin, which expands the grid with one more reel.

The symbols are the green and yellow 7, the green BAR and the green multiplier wild. They appear giant on the reel/reels. The gameplay is entertaining and unique. You will see the grid shifting to expand and reset to normal consisting of 1 to 7 reels. The game menu is on the bottom right of the screen. The jackpot is displayed in golden on the bottom of the reels.

You will be listening to melodic and dynamic music with plenty of electronic sounds. They mark the spinning of the reels and the wins. Crazy Tooth Studio is an unpopular developer. But it has done excellent work with the creation of this slot. The theme looks like a theatre stage with attractive curtains revealing more of it on each lucky spin.

Seven 7s Gameplay

This is a single pay-line game with 3 symbols and 1 to 7 reels when the grid expands to the maximum. You start with the default mode of 1 reel and 1 pay-line. The game uses a new mechanics called Continuwin and this is how it works. If you initially land the 7 symbol you will get another reel added to the grid and a free respin.

If you get a second 7 symbol you will be paid 2 times your stake. Then the grid will expand with another reel and landing a 3rd 7 results in 10 times your stake win. Each winning combination with an extra 7 symbol expands the grid with one more reel and gives you a payout. The latter is the following: 4, 5 and 6 symbols of the lucky 7 give you 25, 75 and 250 times your stake, respectively.

The jackpot in the game is 25,000 times your stake and you win it when you land seven 7s, which is where the game takes its name. The key to advancing in the game and scoring wins is to keep landing more of the lucky 7 symbols.

The other symbol in the game is the 2x and it is a wild multiplier. It substitutes the 7 and increases the payout by doubling it. You can see it landing on reels 2, 3, 5 and 6 only. It doubles all wins except the jackpot. The latter is fixed at 25,000 times your stake at the most.

The BAR is the only symbol that doesn’t pay anything and results in a losing spin. It is a blank symbol. Playing the game we noticed that wins rain pretty often. So, you will e not only have fun but also grab some cash from the rounds.

The Conclusion

Seven 7s looks like a classic slot machine in the beginning but it is much more than that. Once you start playing it you will notice its impressive winning potential and fun features. The new Coninuwin game engine, the expanding and shifting grid grant fun time and a lot of wins. Wait for the slot’s release in February and try it via the free demo. You can play for real in the regulated online casino we have listed on our website.
