Paylines
25 fixed paylines
Two oversized chemistry flasks loom on either side of the reels, one bubbling green, one violet, both rendered in that hand-drawn cartoon style Habanero leaned on in the early 2010s. Behind the grid you can spot a tiled wall, a tesla coil, and the silhouette of a Frankenstein-style operating table in the background. The wordmark sits up top in a bolted scientific font with sparks on either side. It is, without question, a 2013 game. And that is part of the charm.
The grid is a standard 5×3 with 25 fixed paylines paying left-to-right only. No win-both-ways, no Megaways, no cluster math. What it does have is a tripling Mad Scientist Wild that subs for every symbol except the Scatter and applies a 3x multiplier to any line he completes. Three or more Scatters anywhere on the reels open Free Games, and each scatter in the trigger awards 3 free spins, so four scatters give 12, five give 15. Crucially, during free spins every line win is multiplied by 3 again, which means a wild-assisted free-games hit lands at 9x its paytable value.
The symbol set is where the lab-comedy theme really lives. A frog with its tongue out, a mouse on a hamster wheel, a purple octopus reaching out of a teacup, a jar of toxic goo with a skull-and-crossbones, a microscope, a glowing magic orb, and a magnifying glass over notebook paper for the lower-pay tier. Card royals 9 through A fill the bottom of the paytable in a chunky scientific-display font. Above the reels sits a dual random progressive ticker, the Grand and the Minor, and both are time-triggered rather than symbol-triggered, so either can drop on any paid spin without warning.
After every base-game win the classic Habanero Gamble button appears, a card flip for double or quadruple. The math here leans on multiplier interaction rather than a single huge paytable hit. No Buy Feature, no Ante, no Super Bet, this game predates all of that. The presentation is dated in a way newer slots are not, and the audio loops can grate after a long session, but the core mechanic still works. This is an official Habanero partner release on Respinix.
