Immortal 5

Relax Gaming built Immortal 5 around a five-strong roster of homegrown superheroes patrolling a modern city skyline with a futuristic edge, as though its heroes were engineered rather than born with their powers. The look favours a comic-book palette without leaning on any licensed universe, and the cast poses across the reels in costume rather than street clothes.

Play runs on a 5x5 grid evaluated across 15 paylines, with bets from 0.10 to 100 and a default RTP of 96.1% at maximum volatility. The four card suits fill the low end of the paytable, worth up to the bet itself for five in a row, while the five costumed heroes pay between 3 and 20 times the bet for a full line. Two wild types substitute for every paying symbol and pay 20 times the bet for five of a kind, and the game's Expanding Hero Wilds can land on any reel, spreading across the full column with a multiplier of anywhere from 2x to 100x; when more than one appears in the same win, their multipliers add together rather than replacing each other.

Any Immortal wild landing on a normal spin locks in place and hands out a respin, and the process repeats for as long as fresh Immortal wilds keep appearing, ending only once a respin produces none. Separately, the Immortal 5 Wild Feature can trigger unprompted on any base spin, singling out between one and all five reels in turn and converting each into an expanding Hero Wild before the untouched reels spin and the win is evaluated.

Scatter symbols confined to the last three reels can trigger either of two bonus rounds. Three Silver Bonus scatters open a choice between two Hero Modes, each starting with 6 free spins: one carries a single running multiplier for every win that climbs whenever a multiplier symbol lands or an Expanding Hero Wild appears, while the other gives every grid position its own multiplier that doubles each time it contributes to a win, with an expanding wild collecting whatever multiplier its reel is holding and locking that total in place. Before either mode begins, two mystery picks hand out power-ups, covering extra free spins, a bigger starting or per-position multiplier, or additional expanding wilds on the reels, and picking the same one twice doubles its effect. Neither Hero Mode can retrigger within itself.

Three Golden Bonus scatters instead unlock the Immortal Gold Bonus, again offering the same two Hero Modes over 6 free spins but with three mystery picks rather than two, the third being a Super Power-Up that either turns a random medium-value symbol into a standard wild wherever it lands, converts one whole reel into an expanding Hero Wild from the start, or adds a further six free spins outright.

Two optional Hero Bets sit alongside the standard bet: paying 1.5 times the bet improves the odds of triggering either bonus, while 5 times the bet skews the reels toward Golden Bonus scatters only, at the cost of switching off the Immortal 5 Wild Feature entirely, and both raise the frequency of expanding wilds landing in the base game. A feature-buy menu also sells a guaranteed Silver or Gold Bonus trigger for 100 times the bet, or a single Hero Spin for 500 times the bet that either returns nothing or pays out the full 10,000x cap. With a 19.67% hit frequency and volatility rated 10 out of 10, Immortal 5 spends long stretches between wins on the base game, leaning on the respin chain and the stacked Hero Wild multipliers in the bonus rounds to deliver its bigger payouts.
