Mystery 7s is a slot machine that iSoftBet designed and released in 2017. The game is modeled after the stars and after classic slots at the same time, with the bigger focus being on the latter side.
For Mystery 7s, the game features a total of 25 lines and it uses 5 reels to keep them active. A big reward in a game like this would have a top value of $10,000. As for the features, those would give you scatter symbols, free spins, bonus games and multipliers.
Betting and Prizes
Logically, since you’re using 25 lines each round, you need to have a similar number of coins to cover them all and activate them. It’s not true of all games, but in this case that’s how it works. You get to set the value for the 25 coins, using denominations between $0.01 and $1. The resulting range for your bets will be from $0.25 to $25.
The right combination of symbols can be very profitable in this case, paying up to $2,000 in the base game, or $10,000 in one of the free spins. You can see it in the 97.40% RTP that Mystery 7s has, that it can be a game that’s more profitable than most slots.
Mystery 7s Slot Features
There will not be as many feature symbols in the base game of Mystery 7s, as there are in other slot machines. You will get only one actually, a Bonus symbol that shows you an orange thunderbolt. The scatter symbol is present on all reels, but it is of use to you only if you get a minimum of three to make an appearance. With that many Bonus symbols, you will get access to the bonus game.
The bonus game that you will be taken to next will have mystery boxes for you to choose from. These can bring you free spins with multipliers, or direct cash prizes. These cash prizes could get you up to 6,000 coins, which is a decent reward by itself. As for the free spins, the best possible outcome seems to be a feature with 5 free spins and a 5x multiplier. Other examples of rewards include 10 spins with 2x multipliers, 10 spins with 3x multipliers, 50 spins with 2x multipliers, or even free spins with no multipliers. The exact outcome seems to be a bit random, so you might get different results when you’re playing this feature.
When you’re actually inside the free spins, the bonus symbols that appear on the reels will pay as scatters, offering rewards of 2x to 30x total bet, based on the number of positions they occupy. You can’t retrigger the bonus feature once you’re in the free spins.
Theme & Design
The theme might show you the star filled sky in the background, but on the reels the symbols are the classic ones, and they’re not interesting at all. You might get a decent quality out of them, but the images that you’re being shown will be of logos, diamonds, orange 7s, blue 7s, a gold star and three Bar symbols with one to three logos stacked on top of each other.
Mystery 7s has its high average RTP doing a lot of work in its favor, but there are also plenty of other reasons for you to skip it.
