Aftermath by NetEnt follows a group of survivors through the ruins of an AI-driven disaster. Their makeshift weapons double as reel symbols, while explosives can break open more of the playing area.
It joins our slot games with an expanding grid and a multiplier that grows with winning combinations. During free spins, both carry over between spins.
The survivors look suitably resourceful: one wears a bucket as a helmet, another a colander. Weapons and painted card letters appear against corrugated metal, with ruined buildings and overgrown surroundings behind the grid. The battered multiplier display fits the scrapyard look, keeping the theme present even in the game’s controls.
Winning symbols disappear and new symbols fill their places. This repeats until no further wins form. Each winning combination adds +1 to the multiplier for subsequent wins. The multiplier resets between base-game spins but remains throughout either free spins round.
Bomb and Purge can unlock positions, expanding the initial four-reel, six-row grid to a maximum of six reels and eight rows. Open positions remain available throughout an Avalanche sequence. They reset after a base-game spin but stay open throughout free spins.
Bombs remain fixed during Avalanches, then explode once the sequence finishes. Each removes itself, surrounding regular symbols and affected locked positions, making space for another Avalanche. Every exploding Bomb also doubles the current multiplier.
Upgrade replaces itself and a random number of low-paying symbols with either the highest or second-highest paying symbol, selected randomly.
Change converts itself and surrounding regular symbols into one randomly selected regular symbol from those neighbouring positions. Without a neighbouring regular symbol, it becomes the highest-paying symbol.
Purge removes itself, all wall sections and all low and medium-paying symbols. The newly available positions then fill through another Avalanche. Special features resolve after Avalanches, in the order Bomb, Upgrade, Change and Purge.
Three, four or five scatters award eight, ten or twelve free spins. Special Wilds showing +2 can appear; when one participates in a win, its value increases the multiplier for each winning combination obtained. Each scatter adds three spins. A Super Scatter also adds three and upgrades the round to Super Free Spins.
Three, four or five scatters including a Super Scatter award eight, ten or twelve Super Free Spins. Every spin guarantees a Special Wild showing a randomly selected increase from +3 to +10, applied when it participates in a win. Up to one scatter can land per spin, adding three more spins.
Aftermath uses Scatter Pays: eight or more matching symbols anywhere on the grid form a win, without fixed paylines or a left-to-right requirement. Different symbol wins are added together, with only the highest award paid for each symbol combination. The maximum payout is 25,000x the bet.
We like how NetEnt makes the setting part of the action: bombs open the grid, while improvised equipment changes the symbols. Within our online casino, Aftermath suits players who enjoy several features interacting during one spin. There is plenty to follow, especially when free spins preserve the expanded grid and multiplier.
