Seven 7’s is one of the most original classic-themed slots I’ve seen. That’s down to the CONTINUWIN™ feature: the game starts with just one reel, but you can add up to six more if you land the all-important lucky 7. There’s just one payline and only three symbols, including a 2x wild multiplier that can double your wins. Seven 7’s is a highly volatile slot with a top prize of 25,000x your stake to be won.

Seven 7’s has the same control setup you might recognize from other Crazy Tooth Studio slots. The command panel to the right of the reel is compact and conveniently designed.
Click on the button labelled with casino chips to open the stake menu, then use the up and down arrows to scroll through the betting options. Use the spin button underneath the panel to play Seven 7’s.
The button with the fast forward sign activates quick spin mode for faster gameplay, and the menu button at the top offers access to the paytable and settings. It’s best to check the paytable before playing to learn how Seven 7’s works.
I think Seven 7s has the smallest set of symbols I’ve seen in a slot, but they’re all stylish and fit the luxurious aesthetic nicely.
The 7 is the main symbol. You only need to land two of these on the reels to win a prize, but the payouts increase with each extra seven you land (up to a maximum of 7). Get 2, 3, 4, 5, 6, or 7 on the payline to win 2x, 10x, 25x, 75x, 250x, or 25,000x your bet, respectively.
The x2 wild multiplier doubles payouts but only lands on reels 2, 3, 5, and 6. The BAR symbol can appear on any spin, but as it’s a blocker, it doesn’t pay. Instead, it only stops you from landing winning combinations.
There’s just one payline; landing seven symbols across it is the only way to win. Get at least two seven symbols to build a winning combination. Each seven that appears will add a new reel and give you a better chance of winning bigger prizes.
The lack of bonuses in Seven 7’s surprised me initially, but the more I played, the more I realized how brilliantly the game has been constructed. The CONTINUWIN feature is essential, but the 2x wild multiplier is also crucial, as it can lead to higher payouts.
Crazy Tooth Studio’s CONTINUWIN feature gradually adds reels to the game. If you land a seven or a 2x wild multiplier on the first reel, a second reel will appear to the right. The new reel will then respin automatically, and if a seven or 2x symbol lands, a third reel will be added. This can continue automatically until you have seven reels in play.
However, if you land a BAR symbol or a reel stops between symbols, the game will reset, and you’ll return to playing with just one reel.
The 2x wild multiplier substitutes for the 7 to help you win and unlock new reels. Each 2x wild multiplier featuring a winning combination of 6 or fewer symbols will double the prize.
Seven 7’s offers a spectacular max win of 25,000x your bet (or $250,000 when playing at the highest bet). You’ll need to land seven symbols to get the highest payout, which isn’t easy (especially with high volatility).
Not only does Seven 7’s offer a potentially massive top prize, but it has a theoretical Return to Player (RTP) well above the 96% average — 96.60%. That can lead to returns of $96.60 for each $100 wagered overall, but that’s not guaranteed. Returns can be lower or higher than the RTP.
Seven 7’s high volatility means payouts can reach high levels, but the chances of lining up 7s or 2x wild multipliers on every reel are slim. When I played Seven 7’s, I added a second and third reel multiple times, but not a fourth. The third reel would regularly stop between symbols or on a BAR. As a result, my winnings stayed low.
Crazy Tooth Studio has created a striking and unique aesthetic for Seven 7’s. Even though I found the design a little odd at first, I started to like it more as I played.
The reels are surrounded by delicate pieces of metal shaped into an intricate, multicoloured pattern. The game starts zoomed in close to the first reel, but it zooms out further and further as more reels appear.
A traditional mechanical sound effect accompanies each spin, and gentle music plays between spins. However, the music becomes more exciting and adventurous when new reels are unlocked.
Given the unique nature of Seven 7’s, I’d recommend trying the demo version before you play the entire game. Our free demo is ideal for testing the game without wagering real money. You can place virtual bets on thousands of free spins while exploring the game and learning how the mechanics work.
Seven 7’s is one of the most original classic-themed slots I’ve seen, but plenty of other titles feature traditional symbols and simple gameplay.
Deco Diamonds Deluxe has a more conventionally luxurious and elegant style than Seven 7’s. It features fruits and other classic symbols, but each has embedded diamonds. Bonuses include a Bonus Wheel, Just For The Boost Nudge, and Re-Spin.
In 777 Super BIG BuildUp II Double Deluxe, you can spin fruits, dice, and 7s to win up to 6,496x your bet. The Double Deluxe and Free Spins features can help you reach the top wins.
7s Wild is a streamlined slot with a Free Spins feature and a max win of 1,000x your bet. If you want to keep things simple, this is worth a look.
While slightly baffled by Seven 7’s, I soon enjoyed it. Beginning with one reel and adding more creates a fresh slot experience, which is ideal if you want to try something new. Unlocking all seven reels allows you to win the top prize of 25,000x your stake.
However, the high volatility can make winning the bigger prizes seem challenging. I played for a while but didn’t get past three reels. That means payouts will likely stay small until you get lucky enough to play with five or more reels.
Players who love multiple bonuses in slots may also feel that Seven 7’s isn’t right for them, as will others who prefer a more conventional classic-themed slot. But for sheer originality and potentially high payouts, Seven 7’s is at least worth a try.
