Red Rascal Slot by Hacksaw Gaming

Everything pivots on the Pendulum. When three or more Rascal symbols land, they stick to the grid and trigger respins. New Rascals keep the sequence going, and any that form square clusters - 2x2, 3x3, 4x4, all the way up to a full 5x5 - merge into Colossal Rascals. But the payout doesn't happen yet. A swinging Pendulum appears at the start of the respin sequence, alternating between Coin Mode and Wild Mode with each respin. Whichever side it lands on when the sequence ends determines how those sticky Rascals resolve. Coin Mode converts them into cash values between 0.2x and 500x, with Colossals getting their own multiplicative boost (a 2x2 Colossal coin multiplies its value by up to x100). Wild Mode turns them all into Wilds instead, locks them in place, and runs one more spin with regular symbols filling the remaining positions. Colossal Wilds in this mode carry additive multipliers on any line they help complete.

Filling the entire 5x5 with a single Colossal Rascal pays 15,000x outright, no Pendulum needed. That's the ceiling, and it applies during the base game too - not just bonuses. Three tiered free spin rounds sit behind the FS scatter: Ready to Riot gives 8 spins with boosted Rascal frequency, After Dark gives 10 spins and saves any Rascals that don't trigger a respin into a "Popcorn Bucket" that dumps them all onto the grid on the final spin, and Ignite the Night (which needs all five scatters) guarantees 4+ Rascals every single spin with the Pendulum activating on each one rather than just at the end of a respin chain.

Three FeatureSpins options bypass the scatter hunt entirely. Bonushunt makes bonus triggers 10x more likely on each spin. Fiery guarantees at least 3 Rascals per spin, forcing a respin sequence every time. Frenzied Epic Drop guarantees 10+ Rascals per spin - basically fast-tracking toward those Colossal formations. None of the three modes allow FS symbols to land, so you're locked out of the free spin bonuses while using them.

The whole thing is wrapped in a dark carnival that leans creepy rather than festive - a horned devil character in a brown-gold palette clutching a green potion stands beside the reels, with mushroom-topped carnival stalls and string lights glowing faintly behind. High-paying symbols are coloured potion bottles (pink, blue, green, amber) while the lows are puffy grey card values that almost disappear against the blackened grid. Dead symbols - blank spaces that do nothing - fill unused positions during respins, which keeps the visual clean but also means only Rascals matter once the sequence starts.
