PG Soft announced the release of its new video slot, Thunder Reckoning, on October 20, 2026. The title draws inspiration from Norse mythology and the thunder god Thor, transporting players to a frozen mountaintop setting lined with ruined stone columns where a red-bearded warrior brandishes his hammer.
Thunder Reckoning operates on a 5×6 symbol combination matrix utilizing collapsing reels. Winning combinations form when eight or more matching symbols land anywhere on the grid. Winning icons then explode, allowing new symbols to cascade down from above.
Every win leaves a permanent mark on the grid position; the first win partially activates a position, while a second win fully activates it. Adjacent fully activated positions merge into larger blocks starting at 2×2 and scaling up to 5×5. If every position on the reels becomes fully activated, the entire board merges into a single 5×6 block.
Prize symbols and cascade mechanics
When the cascade sequence concludes, the Prize Symbols Feature converts every fully activated position into a Prize symbol corresponding to its merged dimensions. Single Prize symbols award between 0.25x and 1x the bet, 2×2 blocks pay 5x to 10x, and 3×3 blocks deliver 20x to 200x. Larger configurations yield substantial returns, with 4×4 blocks paying 50x to 500x and 5×5 blocks awarding 200x to 1,000x the bet. Charging the complete 5×6 grid awards between 1,000x and 5,000x the bet.
Three Scatter symbols trigger the Free Spins Feature, awarding 10 initial free spins plus two additional spins for each extra Scatter landed. During this bonus round, all grid positions begin partially activated, and activation progress persists for the duration of the feature. The Prize Symbols Feature triggers after the final free spin plays out, and free spins can also be retriggered. Players seeking immediate access can utilize the Feature Buy option to enter the bonus round directly at the displayed cost. The maximum potential payout for Thunder Reckoning reaches 5,000x the bet.
Commenting on the launch, a PG Soft spokesperson said:
“We expect Thunder Reckoning to cause quite the storm with players when they have the chance to experience it. Each win lights up a bit more of the grid, so you can actually watch a big Prize symbol taking shape before it pays out. Free spins are where it gets really fun, because nothing resets and the whole board can end up charged.”
