Mega Heist Slot by Relax Gaming

A moonlit prison yard frames the 5x4 grid, watchtowers and concrete walls boxed in by yellow industrial lamps that flicker against the night. The MEGA HEIST logo hangs above the reels on a battered metal sign, blue and red letters scratched up like they've already been through one job. Symbols mix prison flavor with playing-card lows: orange spades, green clovers, blue diamonds and red hearts at the bottom, then white dice, silver handcuffs and a pink soap bar in the middle, with a bald grinning inmate and a fiery getaway scene anchoring the high pays. The Bonus is a flashing red alarm strapped to a guard's shoulders, and that's where the entire game points.

Wins use 178 connected ways, which is Relax Gaming's spin on the standard ways model. Matches form across adjacent reels but only when the next symbol sits in the same row, one row up or one row down from the previous one. Wilds substitute for everything except the Bonus, and stacked symbols on a reel multiply the payout, so a fully blocked reel of inmates pays substantially more than a single hit. Only the longest combo per symbol pays, which keeps the math honest.

Two Bonus symbols trigger the Escape Bonus, a mini-feature where up to four robbers spawn in column one carrying multiplier prizes, then advance one column right per round while up to four policemen drop in from the top row to catch them. Robbers reaching the column-five Safe zone bank their prizes, caught ones lose them. If a robber happens to be carrying an extra Bonus symbol when he escapes, the round upgrades into the main feature.

That main feature is the Mega Heist Bonus, triggered by 3, 4 or 5 Bonus symbols and built across three sequential locations. Gas Station starts the bank counter at 150x bet. Club bumps it to 1,500x and unlocks the Bus and Signal Distractor power-ups. Bank tops out at 15,000x with every power-up live: Multipliers (2x to 10x), Police Disguise (uncatchable robbers), Extra Robbers, Motorcycle, Bus and the Signal Distractor that shuts down the police for a round. Each robber's prize deducts from the bank counter, and when the counter hits zero, all remaining multipliers transform into Police Disguises and the level ends. Clear all three and the game-wide cap of 16,591x comes into play.

The 150x Buy Bonus jumps straight into the Mega Heist round with a random 3, 4 or 5 Bonus symbols awarded, starting you with 10, 15 or 30 robbers in the pool respectively. For other Relax titles in the wider crime family, this is closer to a Money Train cousin than a Temple Tumble follow-up, the bank counters do the same job as the persistent collect mechanic but with a chase layered on top.
