The Dead Escape Slot by Habanero

Most slots only pay one way. This one is bidirectional on every payline. Whichever side a winning combo starts from, the matching symbols register the same prize, so a king-king-king run from reel 5 inward pays the same as the same trio reading off reel 1. With 30 fixed paylines doubling up, the effective win surface is closer to 60 directional reads per spin. That bidirectional math is what holds the design together at low volatility: you hit small payouts often, the variance is shallow, and the math rebalances downward to compensate for the doubled trigger frequency. The bet stays at 30 lines worth regardless.

The expanding wild is the only base-game amplifier. When it lands anywhere on reels 2 through 4 (the middle three), it stretches to fill the full reel and substitutes for everything except the biohazard scatter. With wins resolving both directions, a fully-expanded middle reel can pull double duty on a single spin, completing combinations starting from either end of the grid. The yellow triangular biohazard symbol is the trigger for the bonus round, and it also pays out directly when three or more land scattered across the reels.

The free games round runs 15 to 30 spins depending on how many scatters triggered it. There's no standard retrigger here, which is unusual for a Habanero release of this era. Instead, every zombie bonus symbol that lands during the round adds exactly one extra free spin to the running counter. Land a heavy stack of those bonus zombies and you can stretch the round out a long way past its starting allocation, but each individual symbol only adds one, so the extension feels gradual rather than dramatic. There's no buy-in or ante-bet shortcut into the round, just the scatter trigger.

Visually it's pure pre-2020 zombie-apocalypse pulp. A bearded male survivor stares out from the high-pay tier with several days of grime on him, an orange pickup truck sits as a getaway-vehicle symbol, a severed zombie hand reaches up from below as a mid-pay, and the card royals are stamped in distressed blood-red paint across riveted metal panels. The whole reel cabinet is bolted into a chainlink fence with a barbed-wire top, a No Trespassing sign hanging crooked on the left, and the smoking ruins of an unnamed city skyline behind the grid. The DEAD ESCAPE wordmark wears a horror-poster slasher font with red drips. There's a four-tier random progressive jackpot wired in on the operator side (Mini, Minor, Major, Grand) that can drop on any paid spin without a symbol requirement, but it isn't lit up in the demo init, so you only see the base game and bonus running here. It's a small game from Habanero's mid-2010s horror-themed catalog, and what makes it worth playing is the both-ways math, not the bonus economy.
