NetEnt's bird-hero battler where avalanches replace reels
Landing 3+ scatters triggers 8 free spins in one of three randomly chosen worlds: Dark Forest, Firelands, or Ice World. Each world carries its own unique special function that boosts wins in different ways.
When a winning Hero symbol combination explodes, the remaining matching symbols convert into wilds before the next Avalanche, dramatically increasing the odds of chaining further wins. This feature is always active in both the base game and free spins.
Instead of spinning, symbols fall into place and winning combos explode to make room for new symbols cascading from above, allowing multiple wins from a single spin.
This randomly-triggered feature picks one symbol color to survive while destroying the rest of the board (scatters excepted), refilling the reels with a fresh Avalanche in the process.
In Dark Forest, Spreading Wilds expand into adjacent positions across avalanches, while Ice World's Heavy Wilds linger on the reels through repeated cascades until the round resolves.
Winning hero symbol groups chip away at monster captains' health, and defeating all three captains summons a multi-weak-point Monster Boss whose defeat unlocks a brand-new world with 8 more free spins.
Choose a bet between $0.20 and $400 per round before spinning the 5×5 grid.
Symbols fall into place rather than spin; matches of 3 or more connected horizontally or vertically explode and are replaced by new symbols cascading from above.
Land at least 3 scatter symbols anywhere on the grid to spin a wheel that randomly picks one of three worlds, each awarding 8 free spins with its own special mechanic.
Use hero symbol wins to damage monster captains and, eventually, the Monster Boss — clearing a boss unlocks a new world and more free spins.
Wild Worlds sends three superhero birds into battle against monster captains and a huge boss across three distinct worlds — Dark Forest, Firelands, and Ice World — each unlocked via a free spins roulette wheel triggered by 3 or more scatters; every world layers in its own wild mechanic (Spreading, Random, or Heavy Wilds) on top of the Hero Attack system, where matching hero symbols chip away at monster health until a captain or boss is defeated, unlocking further rounds of 8 free spins.
Rather than a conventional reel-spinner, Wild Worlds plays out like a mini video game: three heroic birds face off against ice, fire, and forest monsters while an Avalanche reel mechanic drives the action across a 5×5 grid. Winning symbol groups explode and new ones cascade down, and the whole board doubles as a battlefield where hero wins reduce monster health bars in real time.
What sets this slot apart is the layering of systems — Hero Wilds convert surviving matched symbols after an explosion, a random Destroy feature clears the board outside of wins, and the three free spins worlds each bring a distinct wild variant to the table. Defeating a monster boss doesn’t just pay out; it unlocks an entirely new world and more free spins, giving sessions a genuine sense of progression.
With a 96.47% RTP and stakes running from $0.20 up to $400 a round, Wild Worlds suits players who want more spectacle and structure than a typical slot offers, wrapped in a colorful, character-driven presentation that plays instantly in any modern browser on desktop or mobile.
Wild Worlds has a return-to-player rate of 96.47%, with the game classified as medium-to-high volatility.
Landing at least 3 scatter symbols anywhere on the 5×5 grid activates a roulette wheel that randomly selects one of three worlds, each starting with 8 free spins.
The three worlds are Dark Forest (Spreading Wilds), Firelands (Random Wilds), and Ice World (Heavy Wilds), each with its own special wild mechanic active during free spins.
Matching 3, 4, or 5 hero symbols of the same color removes 1, 2, or 3 random hit points from monsters, and filling the Hero Meter unlocks a stronger special attack unique to each of the three heroes.
Stakes range from $0.20 up to $400 per round.
