Combo Seven comes with a medium variance level and an RTP rate of 95.05%. Medium-high-volatility slots are known for being quite predictable and consistent and offer a better gaming experience than low-volatility or high-volatility games.

Combo Seven

Onlyplay has clearly aimed at creating a retro-looking game while designing Combo Seven. The slot has generic graphics that look dated, honestly. The audio isn’t impressive, too, and we can describe the game’s audio-visual presentation as mediocre.

The reels are set against the orange-yellow fade background and are framed with flashing lamps. To the left of the reels, three jackpot prizes are displayed according to the current bet size. The paytable consists of colored 7’s symbols that offer payouts between 0.5x and 50x for combinations of 3 matching icons. That’s the only possible winning combination as the game has only 3 reels.

The Free Spins symbol is the game’s Scatter and landing 3 of them anywhere in view, you’ll activate a bonus round with 10 free spins.
