Combo Seven Review

Classic slots have always been relevant and remain highly popular among thousands of gamblers to this day, so it’s no surprise we still see dozens of retro-inspired games constantly being released each year. However, they hardly innovate and, in most cases, are extremely formulaic, offering a similar gaming experience. Luckily, it’s not the case with Onlyplay’s Combo Seven slot, which despite its classic appearance enlivens the gameplay with free spins and three different jackpots.

On the outside, Combo Seven doesn’t look very promising with its 3x3 reels and 5 win lines, but it’s still worth noting that the game has pretty high production values. The graphics are nice and sharp, and there are a lot of animations that add a touch of life to the action. The team has put a lot of effort into the soundtrack as well, as classy funky music plays whilst you spin the reels and picks up the tempo when you hit wins or bonus features.

Combo Seven Slot - Reel Screen

On top of being designed for a specific taste, Combo Seven also caters to a specific audience. As far as the betting range starts from £1 per spin, there aren’t many options for lower-stake punters, while bets up to £50 per spin are available for high-rollers. The volatility is in the medium range, and the RTP is below the average level at 95.16%. As for wins, they tend to occur in 1 out of 5 spins according to the 20.4% hit rate, and the maximum possible payout is 2,530x the bet.

As the name implies, Combo Seven is all about, well, sevens, so don’t expect to see anything except sevens here, pardon the tautology. The symbol collection includes 8 symbols of lucky 7’s, which come in different colors and have values ranging from 0.5x to 50x the stake. Unfortunately, Wilds are omitted.

Combo Seven Slot Features

Combo Seven Slot - Free Spins

In addition to line wins, the three top-tier sevens can bring you one of the three fixed jackpot prizes, namely Mini, Major, and Grand, which are awarded when 9 of the same kind appear simultaneously on the reels:

  • Full-screen of green 7’s - awards a Mini jackpot of 25x the bet.
  • Full-screen of red 7’s - awards a Major jackpot of 100x the bet.
  • Full-screen of orange 7’s - awards a Grand jackpot of 1,000x the bet.

Look out for Scatter symbols. Landing 3 anywhere on the reels triggers 10 Free Spins. The bonus game operates in a similar way to the base game, and retriggers are not possible.

Review Summary

All up, there’s not much to say about the Combo Seven slot. It’s a typical classic slot with a few tricks of its own to broaden the experience. The jackpots probably will be the main reason why players might feel drawn to spin the reels on it. Aside from that, there’s not too much entertainment to be found here.


  • High production values
  • Three jackpot prizes


  • Lower-than-average RTP
  • Lack of features
