Mega Heist

Relax Gaming frames Mega Heist as a prison break gone bigger: the base game opens on a top-down view of a cell block, barred doors to one side and barbed wire fencing closing in the rest of the frame, rendered in a cartoonish house style. Getting free is only the setup — the payoff comes in a three-location bonus chain that sends robbers on to hit a gas station, a nightclub, and finally a bank.

The base game runs on a five-reel, four-row grid with 178 ways to win. Matching symbols must begin on the leftmost reel and chain across adjacent reels, staying level with the previous symbol or shifting by exactly one row up or down to keep the connection alive. Eleven symbols make up the paytable: four card-suit icons pay the least, a bar of soap, a pair of dice, and a set of handcuffs sit in the middle, and three crook characters plus a policeman make up the top tier. Five of a kind pays 2x the stake for the low suits, 3x for the mid-tier trio, and anywhere from 6x to 20x for the top symbols, while a sunglasses-wearing 'W' wild fills in for any of them. Stakes run from 0.10 to 50 per spin across a high-volatility, 5-out-of-5-rated math model, with a base RTP of 96.19% that rises slightly to 96.5% when the bonus is bought outright, and a published hit frequency of 20.07%.

Two bonus symbols landing in the base game set off the Escape Bonus: up to four robbers appear and move left to right across their own grid, each one carrying either a prize multiplier or an extra bonus symbol, while roaming policemen can catch and eliminate them along the way. Robbers who reach the Safe Zone on the right bank whatever they were carrying, and the round ends once none are left in play. If a robber holding a bonus symbol makes it through, the escape spills straight into the Mega Heist Bonus and adds up to three extra bonus symbols to the total going in.

Landing three, four, or five bonus symbols directly in the base game — or chaining in from a successful escape — opens the Mega Heist Bonus itself with 10, 15, or 30 robbers to work with. The heist runs across three escalating locations: the gas station pays up to 150x the stake, the club up to 1,500x, and the bank up to 15,000x. Robbers again move left to right, banking their carried multiplier at the rightmost Safe Zone reel before rejoining the pool to make another run, while police continue to pick them off along the way. Every multiplier a robber banks chips away at that level's target counter, and hitting zero advances the heist to the next, higher-paying location; the round only ends once the robber pool and the active zone are both empty.

Power-ups add further variance: some boost a robber's carried multiplier as high as 10x or add extra robbers to the pool, others remove the threat outright by disguising a robber or clearing police from the round entirely, and a motorbike or bus can ferry two or eight robbers to safety in a single trip. Not every power-up appears at every level.

Buying in costs 150x the bet and drops players straight into the Mega Heist Bonus already stocked with 10, 15, or 30 robbers, bypassing the base game's bonus-symbol hunt. Across the three escalating locations, Mega Heist's maximum win reaches 16,591x the stake, built from its bonus chain rather than a single standalone feature.
