Seven 7’s Slot Machine (Microgaming & Crazy Tooth)

Seven 7’s SlotMicrogaming, in partnership with Crazy Tooth Studio, has developed a slot game by the title Seven 7’s.

So, what does Seven 7’s has in store for you?

Below is my review on this slot, and I hope you will find it informative enough before you can invest in this game.

First and foremost, Seven 7’s slot comes to you on 1 reel. However, there is potential for the reels to expand to as many as 7 reels.

If you manage to fully expand the game area, the slot’s only payline has the potential to form a winning combination of up to 25,000x the stake (which is equivalent to $250,000).

There are several features on this slot but the most notable ones are the wild multipliers, expanding reels, and just three symbols.

Betting And Prizes

Bet costs from a low of $0.20 to a high of $10 per spin. This is a little unusual coming from a popular developer like Microgaming.

At first, I was a little discouraged by this low bet amounts, however, I came to find out that there is potential to walk away with as much as $250,000 in a single spin when using the maximum bet amount.

Seven 7’s slot game comes with extremely high volatility, but it’s RTP of 96.60% helps to cool things a little.

Seven 7’s Slot Features

The continued advance in technology has seen a major shift with the way developers do things.

Currently, we have witnessed a number of game developers use the latest game engine known as Continuwin.

In this system, Microgaming starts with a single reel position (1x1), with one of three possible symbols.

The three symbols are a Bar Logo, a 7 symbol, or a 2x Wild Multiplier.

Out of the three, the one with the least advantage is the Bar since it only acts as the blocker and has no payments.

The 2x Wild multiplier (7) can only appear on the 2nd and 6th reel. It also has the potential to double your win. However, this will not be in a position to double the value of the highest jackpot.

The 7 is the symbol that you use to form winning combinations. When you land a 7 on reel 1, you will be able to trigger a re-spin. Thereafter, reel 1 will get locked and at this point, a second reel will be added.

In case there is a 7 or a 2x Wild on the second reel, the game’s re-spins will continue. This can end up giving you up to 7 symbols which will then help you form a winning combo.

Theme & Design

The use of bar symbols and 7 indicate that this slot is a classic themed slot. Although its inspiration is from the olden days, much of the graphics are quite modern, which makes them very pretty.


Seven 7’s is the most unique slot game that I have ever come across. Although the slot is quite volatile, it has the potential to bring you some decent winnings.

If you want to play this slot game for real cash, note that it is very volatile, and you might want to practice with a free demo before putting real money in it.
