Lil' Demon: Double Heat Slot by Playtech

Everything hinges on one square. The middle of the board holds the Demon Zone, and the grinning red Lil Demon Wild lands nowhere else - reel three, second row, that spot only. When he turns up, he scoops the value off every Cash Prize and Special Prize coin sitting in view and flings the gold into the two bubbling cauldron pots perched over the reels.

The coins come in two flavours. Cash Prize coins carry a small printed amount, up to roughly 1.5x each. Special Prize coins hold a jackpot tier instead: Mini at 5x, Minor at 10x, Major at 75x, or the Mega worth 1,000x. Neither type pays on a line. They only count once the Demon collects them, which is what makes his appearances the whole show. Miss him and a spin is just horned card royals doing quiet line work.

Those gold pots are the route into Free Games. Every collection throws more coins into one or both cauldrons, and the fuller a pot gets, the better its odds of tipping over into the bonus. Each pot that goes awards six free games. In there the Demon stops wandering - he locks into the Demon Zone and collects on every single spin, no landing required. He can also enhance the reels, forcing a random batch of positions to come in as Cash or Special Prize coins, and he keeps feeding the pots to claw back more spins.

The base game has a safety net called Rewind. If the Demon misses the zone, there's a random chance it rewinds and drops him back in. And when he does land, a random number of those demon-horned royals can rewind into Special Prize coins after the fact. Want two collectors at once? The +25% Extra Bet toggle bolts a second Demon Zone onto the grid. No buy feature here, so the pots are the only way in - fitting for a cartoon underworld of purple dusk skies, jagged violet peaks and orange lava, with a red imp lounging on a golden throne up top.
