About Jack Frost's Winter

Released on December 14, 2020, Jack Frost's Winter is PG Soft's second Infinity Reels title (after Buffalo Win), and the most accomplished. The initial grid of 3 rows x 4 reels expands without limit to the right: every win involving the rightmost reel adds an extra reel, as long as the chain continues. Expanding wilds come to support the sequences. The heart of the potential lies in the free spins, where the progressive multiplier persists from one spin to the next instead of resetting — it is this unlimited expansion + permanent multiplier combination that lifts the ceiling to 100,000x the stake, the maximum of the PG Soft catalogue, served by high volatility. 96.7% RTP, no bonus buy.
