Seven 7s online slot game

Seven 7s slot title, released in February 2020 by Crazy Tooth Studios under Microgaming is an exciting 1 reel and 1 pay line slot that extends into 7 reels where players could win a 25,000x spin bet multiplier which is the Super 7s slot game’s fixed jackpot win.

Theme and Story Line

This is a story that celebrates the slot world’s ‘7-symbol’ which has been around for decades. The Seven 7’s online slot game reunites the ‘7-symbol with the ‘Bar-symbol’, the classic x2-multiplier wild symbol, and the very familiar ‘fixed jackpot win’ in memory of the much-revered casino 7-symbol!

Graphics, Sounds, and Animations

Seven 7’s is a generous display of digital artwork and animated effects! The most impressive feature is watching how smoothly the slot adds new reels to the gameplay with ease. There is absolutely no lag or distortion as the reel extension is executed perfectly whether you are playing on a small mobile screen or large desktop monitor. 

The artwork surrounding the reel(s) is made up of orange, green, and reddish-brown colours which resemble the cheesy décor you would commonly find in land-based casinos. As for the background music, this is a mixture of elegant piano, bass, and tambourine instruments that create a jolly tune while the gameplay uses lively electronic/digital sound effects.

This is arguably one of the easiest slot games you will ever play – there is nothing to it. You will start the gameplay with 1 reel and 1 position for symbols. When the 7-symbol lands the reels seamlessly extend into 2, 3, 4, 5, 6, or 7 reels. Effectively, the slot progressively increases to a 1x1, 2x1, 3x1, 4x1, 5x1, 6x1, and 7x1 slot game.

As a result, no matter how many reels are activated, there is always a single pay line behind them and 1 symbol position on every reel. However, if a bar symbol lands on the reels or the reels stop in between symbols, then the extended reels feature will not be triggered. 

For the reels to extend from 2 to 3 reels or 3 to 4 reels, and so on, a 7-symbol or 2x-symbol must land on the newly formed reel. All reels previously formed will not spin. 

For example, reel 1 spins and produces a 7. Reel 1 will now stick in position (not spin) and reel 2 will spin. If a 2x-symbol or 7-symbol lands on reel 2, the slot will extend to 3 reels. Now reels 1 and 2 will stick in place (not spin) and reel 3 will spin in search of a 2x-symbol or 7 symbols. The process continues with the possibility of reaching a max of 7 reels. 

Each time the x2 symbol lands on the reels, it will count as a wildcard symbol for the 7-symbol and multiply the potential winnings shown on the paytable above the reels by x2.

Payouts are as follows:

  • 7-7 = x2 spin bet multiplier
  • 7-7-7 = x10 spin bet multiplier
  • 7-7-7-7 = x25 spin bet multiplier
  • 7-7-7-7-7 = x75 spin bet multiplier
  • 7-7-7-7-7-7 = x250 spin bet multiplier
  • 7-7-7-7-7-7-7 = x25,000 spin bet multiplier

Spin bet multipliers do not accumulate so you are paid the amount shown at the level you reach, and the level could be multiplied if the x2-multiplier wild symbol is part of the combination. Also, you should note that when you change your bet, the amounts shown in the paytable will auto adjust to show you the cash win and not the multiplier win.

Lastly, you have a few options to enhance your gameplay you can select quick spins, select auto spins with win/loss limits, and turn the slot sounds on/off.

Bet sizes, RTP and Variance

Click on the casino chips symbol to set your bets. The min-max bet is 0.20-10.00 per spin. Your expected long-run RTP is 96.6% and the slot is classed as high variance. Despite the high variance tag, the 7-symbol tends to land on the reels with some regularity but generally serves to keep your bankroll to a reasonable level without dropping too sharply while you will need to hold tight and wait for the slot to extend to 4 or 5 reels where you will etch out bigger wins.


The Seven 7’s online slot title is a brilliant invention coming out of the partnership formed between Crazy Tooth Studios and Microgaming. At first glance, you may be put off by the simplistic single reel set up, but after a few spins, you will more than likely be glued to this game for longer than you might expect. There is something about that 7 symbol, multipliers, and extending reels that makes the Seven 7’s online slot moreish – especially the challenge to extend the slot to display all 7 reels!
