About this Slot
Reactor Core X is a sci-fi themed slot from Hypr Studios with an RTP of 95%, medium volatility and a maximum win of 10,000x. The game uses 5 reels, 5 rows and 50 fixed paylines, all active on every spin.
The Containment Breach bonus round is triggered by scatters: 3 scatters activate the Normal Bonus, while 4 scatters trigger the Super Bonus. The Normal Bonus grants 7 free spins with reel-wide Wilds that build via Reactor Alerts. Each Reactor Alert adds one charge, and every five charges advance one Core level, unlocking extra spins and a multiplier increase. Alerts cannot be collected when covered by Wilds.
The Super Bonus also awards 7 free spins but starts with a 2×2 Wild and a multiplier ranging from 1x to 3x. Reactor Level Ups during the bonus round grant additional spins and increase the multiplier with each advancement.
Hypr Spins is an extreme mode feature offering a random Wild sized between 1×1 and 5×5, paired with a 1000x multiplier.
Four buy options are available. The standard bonus buy grants 7 free spins and bypasses the scatter trigger requirement. The Mystery Bonus buy delivers a random outcome between the Normal Bonus and Super Bonus. The Super Bonus buy provides direct access to the upgraded bonus. The Hypr Spins buy grants immediate entry to the extreme mode feature.
Extra Chance is an optional feature that increases the likelihood of triggering the Containment Breach bonus round.
