Our read of the game, based on the data the studio publishes

Released on September 20, 2018, Reactor is a Sci-Fi / Atomic energy themed slot from Red Tiger. It runs on a 5x3 grid with 20 Bothway paylines, an RTP of 96.02% (below the 96% market average), high volatility, and a max win of 5,000x. The mechanics are rich despite the lack of Free Spins: Random Wilds that appear randomly in the base game, a Random Multiplier that boosts wins, a Mega Symbol 3x3 (a large block) that can land for big payouts, Symbol Swap that turns one symbol into another, and a Respins feature that relaunches a potentially winning combination. Bothway paylines (paying both left-to-right and right-to-left) effectively double the coverage of the 20 paylines. The atomic-energy theme comes with Red Tiger's 2018-era visuals.

❓Reactor FAQ

What is the RTP of Reactor?▾

The official RTP is 96.

02%. Red Tiger often serves several RTP versions depending on the casino — check the in-game "i" button to confirm.

Why doesn't Reactor have Free Spins?▾

It's a 2018-era Red Tiger design choice — a vintage slot with features running entirely on the base game.

The EV comes from Random Wilds, the Random Multiplier, the Mega Symbol, and Respins. For Red Tiger titles with Free Spins, try Dragon's Luck Deluxe or Reel Keeper Power Reels.

How do Bothway paylines work?▾

The 20 paylines pay in both directions (left-to-right AND right-to-left).

A combination that forms right-to-left pays the same as one that forms left-to-right — effectively 40 virtual paylines for the price of 20.

Is Reactor available to play?▾

Yes, it is available at online casinos that carry the Red Tiger catalogue.
