How to Play
The game is based on the unusual Continuwin engine. The session starts with 1 reel, 1 line, and 1 symbol row. It can show you 1 of 3 symbols: Lucky 7, BAR and 2x Wild Multiplier.
Lucky 7 is responsible for winning combinations in this slot. When you land them on the 1st reel, the 1st reel will remain locked and the 2nd will be added and a respin will be awarded. If you get Lucky7 or Wild Multiplier on reel 2, you will get 1 more respin. Consecutive respins will result in more reels and bigger wins. There are 7 maximum reels in the game.
The Wild Multiplier acts like a Lucky 7 symbol and doubles the payout; however, it only appears on reels 2, 3, 5, and 6 so you can't get it the 1st time. BAR is a Bonus symbol that acts as a locker.
Now, when you want to play the game, all you need is to:
- Launch Seven 7's slot
- Read how to create payout combinations
- Check out the rules of bonus features
- Place your bet; it starts at €0.20 and the maximum is €10
- Press the spin button!
The game offers no Scatter symbols but it does have a jackpot, which we’ll talk about below.
Seven 7's RTP and Volatility
Seven 7's can offer players an RTP of 96.60% as well as a high volatility.
This slot machine comes with high volatility so you will have to go through tough challenges to get 7 of a kind Lucky 7 Jackpot! However, there are big prizes and fun gameplay along the way and the theoretical return is 96.60% which is slightly above the market average. The game has a well-balanced math model that will suit most high-risk players.
Theme
When you start the game, you will see a small playing field in a crazy environment full of patterns and fabrics in emerald, gold, and red colors. This should all look gaudy, but it seems like the Crazy Tooth Studio’s design team did a fine job because we are in awe of how beautiful and unusual this game looks! It seems to have been inspired by retro or steampunk or both.
As we said here you can only see 3 symbols: Lucky 7, BAR and 2x Wild Multiplier. Lucky 7 is responsible for winning combinations in this slot.
The Wild Multiplier acts like a Lucky 7 symbol and doubles the payout; however, it only appears on reels 2-6 so you can't get it the first time. BAR is a Bonus symbol that acts as a locker; it doesn’t pay.

Mobile Compatibility

Crazy Tooth Studio created Seven 7's using JS and HTML5 technology, which means you can spin its reels anywhere! At home, in the park, at work, anywhere. Just take your smartphone or tablet with you and have a good internet connection.

Bonus Rounds & Free Spins
Wild Multiplier
2x is the Wild Multiplier and substitutes for all paying symbols. Each Wild Multiplier that lands on a payline of 6 symbols or less multiplies the win payout by 2. The Wild Multiplier can only appear on reels 2, 3, 5, and 6.
Continuwin Added Reels Feature
This slot machine has only 1 reel, but with the Continuwin feature, you can unlock additional reels.
Here’s how it works: when you land a ‘7’ on the payline, the Continuwin will add a new spinning reel. This goes on and on until you land on 7’s symbols of a kind or there is no more options. If you do, you’re up for a great win!
The win you get differs depending on how many symbols you get and the stake you placed. The biggest win you can get here is 25,000x your stake for collecting 7-of-a-kind symbols.

You can hardly call it a slot, as only reel with one position is present. However, it can grow up to 7 positions if you get SEVEN SEVENS in a row.
I’ve tried to catch 3 and it take some times. Finally, 100 spins later I caught the first 777 for x10 and then another 777.
As much as like classic genre and simplicity, this game is not my fav. Imo it’s just way too slow with 100 rolls in like 10 minutes in a fast spin mode.
