Experiment X is a sci-fi laboratory-themed video slot from Uppercut Gaming, released on 17 February 2026 and built on the Stake Engine. The game features a 5-reel, 4-row layout with 14 fixed paylines, combining a mad scientist theme with structured bonus mechanics. Its free spins rounds feature sticky Wilds and a progressive global multiplier, while the Super Bonus starts with a 10× multiplier. With high volatility and a maximum win of 10,000× the base bet, Experiment X is designed for players who enjoy bonus-focused gameplay and escalating win potential.
Experiment X uses 5 reels, 4 rows, and 14 fixed paylines. Wins are formed from left to right when three or more matching symbols appear on adjacent reels.
Wilds substitute for all symbols except Bonus or Scatter symbols. During Free Spins, Wilds become sticky and reset the spin counter whenever they land. A global multiplier applies to all wins during the bonus rounds and increases by 1× after every spin.
Landing 3 Bonus symbols triggers the regular Bonus, while 4 Bonus symbols activate the Super Bonus. Players can also use the Bonus Booster or Bonus Hyper/Superante options to increase their chances of triggering the Bonus, or purchase either bonus feature directly.
Experiment X features a futuristic laboratory setting inspired by scientific experiments and a mad scientist character. Its visual elements include potions, injections, and laboratory-themed motifs. The presentation uses a clean, sterile aesthetic, a modern user interface, and restrained sound design rather than exaggerated cartoon visuals or chaotic animations.
The regular Bonus is triggered by landing 3 Bonus symbols and awards 3 free spins. Wilds become sticky during the feature, and each Wild that lands resets the spin counter to 3. A global multiplier applies to all wins and increases by 1× after every spin.
The Super Bonus is triggered by landing 4 Bonus symbols. It uses the same mechanics as the regular Bonus, including sticky Wilds, spin-counter resets, and a global multiplier that increases by 1× after every spin.
