Seven 7’s Online Slot

Seven 7's online slot by Microgaming and Crazy Tooth Studio is a high volatility 1 to 7-reel slot with 1 fixed payline. This title's design is reminiscent of gambling houses of yesteryear; with a wooden, draped stage forming the background for a twisty-brass motif that frames the game's initial, solo reel. The Game's 3 symbols are all rendered in classic style. This title has uniquely-conceived gameplay, with reels that expand as you progress. The slot's in-game benefits are respins, expanding reels and multiplier wilds to help you spin your way to victory. The minimum and maximum bets for this slot are 0.10 and 10.00 and the game can be played across all devices.

Game Features

Seven 7's  slot is unusual in that there are only 3 game symbols with no specific assigned values.

  • The BAR symbol is a blocker that prevents you from forming winning combinations and expanding the reels. Landing a BAR after a series of 7s ends your winning streak and takes you back to one reel.
  • The 7 is the game's integral symbol which expands the reels and also triggers free spins.
  • The 2x multiplier wild symbol stands in for 7's , giving you twice your winnings as well.

Bonus Features

Expanding Reels / Respins Landing a 7 symbol on the game's first visible reel locks the reel in place, expanding the grid to add another reel, as well as triggering a respin. Each successive 7 you are lucky to land, opens up a new level of winnings, with the goal being to fill seven reels with 7's .

Pay table: 2 of a kind pays 2x your wager. 3 of a kind pays 10x your wager. 4 of a kind pays 25x your wager. 5 of a kind pays 75x your wager. 6 of a kind pays 250x your wager. 7 of a kind pays out a 25,000x jackpot

Multiplier Wilds

The 2x Multiplier wild symbol substitutes for a 7 and allows you to continue expanding the reels while doubling your winnings.

Seven 7's online slot Gameplay


Taking creative risks appears to be the hallmark of Crazy Tooth Studios and Microgaming seems all too happy to host their bold concepts on its platform. The old-timey theme exists in direct juxtaposition to the game's never-before-seen concept. Watching the game's reels expand as you add 7's  and watch your winnings stack up is an indescribable feeling of excitement; however, you should note that the game is highly volatile, so most victories are hard-won. The RTP is an above-average 96.6%, offering some balance to the challenging variance.

The game does not have any standout special features, but any additions might have cluttered your experience as the game, within itself, is a bonus feature wrapped around an online slot concept. While the novelty value here is compelling, whether you will come back to play again is hard to say, and only time will tell whether people can get past the sparse feature offering and enjoy what feels like a purist's slot.
