Grid / Reactions / and Wild Duplication
this slot runs on a 6-reel, 7-row dynamic grid that morphs between spins, creating up to 117,649 Megaways. Premium gemstone symbols land for 1 to 12.5x stake on 6-of-a-kind wins. The core mechanic is Reaction Wins: when symbols connect, they vanish and new ones drop from above, chaining wins as long as the cascade holds.
Wild Duplication fires at random when at least one wild appears on reels 2-5. All symbols sitting above a wild on the same reel flip into wilds themselves, extending cascades and multiplying the reels’ contribution. It sounds fancier than it plays – it’s essentially expanding wilds by another name – but paired with Reactions, it keeps the base game from feeling static.
Pre-Bonus Game and Heart Lives
Land 3 scatters anywhere to enter the pre-bonus phase: a special 4×5 grid where only Hearts and blanks appear. You get 3 respins to start. Each Heart that lands becomes sticky and resets the respin counter to 3. This continues until respins run out or the screen fills with Hearts. The total number of Hearts you collect becomes your bonus lives – up to 20 are possible.
Indefinite Bonus Round with Progressive Multiplier
Once the pre-game ends, the bonus round begins with unlimited free spins and a multiplier starting at x1. Every Reaction Win bumps the multiplier by +1, and crucially, it never resets for the entire bonus duration. Broken Heart symbols remove 1 life each time they land. The round continues until all lives are spent, meaning a strong pre-game haul can run for a long time – and the higher the life count, the higher the multiplier can climb. Payouts scale with this multiplier, reaching up to 24,070x your stake.
Win Exchange and Bonus Buy
If you land between 25 and 99x your stake in the base game, you can gamble that amount for a chance at the bonus round. Win 100x or more and you unlock the Win Exchange: spend 100x your stake to buy the Heart Free Spins directly. Non-UK players and eligible regions can also purchase the bonus outright for 100x the stake, bypassing the base game entirely.
Theme and Presentation
Big Time Gaming has dressed this slot in a retro-futuristic disco-gameshow aesthetic. Two massive pixelated screens in the backdrop display winning symbols, and the gemstone symbols carry a glossy, polished sheen. The vibe is cold and impersonal – less about narrative charm and more about the mechanical spectacle of cascades and multiplier climbs. It works if you’re here for the mechanics; it won’t win you over on atmosphere alone.
