Reactor

Reactor by Red Tiger is a video slot laid out on a grid of 5 reels and 3 rows, offering 20 fixed paylines that pay both ways (left-to-right and right-to-left). The theme is sci-fi and futuristic, with glowing crystals, electric energy orbs, and high-tech mechanical elements set in what feels like a nuclear or energy reactor facility. The wild symbol appears as an orb of energy and can substitute for other symbols to complete wins.

The standout feature in Reactor is its Battery system: landing one or more Battery symbols on a spin triggers a special Respin with escalating reel modifiers depending on how many Batteries appear. One Battery awards a simple Respin; two add a Symbol Swap mechanic that can upgrade low-value symbols; three add Random Wilds; four introduce a Mega Wild that covers multiple positions; landing all five Batteries activates all those modifiers plus a Random Win Multiplier.

There is no traditional Free Spins bonus round in Reactor—everything revolves around the Battery Respin feature activated in the base game. The maximum win potential tops out at 5,000 times the player’s stake, particularly when multiple modifiers align on a spin. The game has high volatility, meaning that wins may be less frequent but can be significant when the feature set is triggered. Reactor does not include a Bonus Buy option.

Overall Reactor focuses on intense base-game action, using its Battery-driven modifiers and dynamic features rather than free spins or bonus rounds to deliver its excitement.
