Interstellar 7s has a space theme, and it influences some elements of its design, but RTG decided to also use classic symbols for its reels, so it’s split between the two genres. A modern slot machine when it comes to features, it offers only 3×3 reels and 5 paylines. You get very low bets to use, $0.05 being sufficient for a single spin. You also have the option to wager up to $25 per spin. They claim that the slot is capped at 10,000x the stake (50,000x the line bet), which seems quite a bit for what the game seems to have in store. The medium volatility is greatly appreciated.
Like plenty of other slot machines that take on a space theme, you don’t see it in their choice of symbols. These are classics, but they do have small decorations and outlines that make the connection to space. Three regular symbols are the BAR logos (1 to 3 stacked), and the other three are Sevens colored in purple, green, or red. There are also Wheel or Asteroid symbols, but they trigger features.
Moving on to the Interstellar 7s features, one of them is the wild that pays up to 500x the stake for its combinations. There are multiplier versions for the 3rd reel. The other is a Bonus Wheel, which can award prizes, jackpots, or free spins with multipliers.
