Jack Frost's Winter

Jack Frost’s Winter overview

Jack Frost’s Winter is PG SOFT’s seasonal take on ReelPlay’s Infinity Reels engine, released in December 2020. The math model pairs a 96.7% RTP with high volatility and a headline win cap of 100,000 × the stake. Starting from a 3-reel, 4-row setup, every evaluated spin can, in theory, stretch the grid indefinitely while a progressive win multiplier climbs one step per extra reel.

How Infinity Reels works in this title

You begin on three 4-symbol reels. A payout that includes the right-most reel prompts the game to bolt a fresh reel onto the right edge and re-evaluate the combination. The sequence continues until no further improvement occurs. When the chain ends, total line wins are multiplied by the current multiplier and credited before the layout resets to 3 reels.

• +1 multiplier for every additional reel
• No upper limit stated in the paytable – theoretical expansion only capped by the 100,000 × ceiling
• Expanding Wilds (reels 2 and beyond) help to lengthen winning chains

Core features explained

• Expanding Wilds – any Wild that lands grows to fill its reel, substituting for all pay symbols. Wilds cannot appear on reel 1.
• Free Spins – three Scatter crystals award 10 complimentary spins; each extra Scatter adds two more.
• Progressive Multiplier – still increases by +1 per reel during the bonus round and, unlike in the base game, does not reset between free-spin drops.
• Bonus boosters – provider text confirms multipliers and extra-spin boosters. Some third-party sources mention special Heart (+1 spin) and Star (+1 multiplier) icons; verify their presence in the in-game rules of your jurisdiction.

RTP, volatility & bankroll considerations

The disclosed 96.7% theoretical return sits slightly above the modern industry average. High volatility means long stretches of quiet play punctuated by streaky reel-adding sequences. Plan a budget that can absorb prolonged dry spells and consider reducing coin value if chasing the maximum potential.

Mobile optimisation & user interface

Built in JavaScript/HTML5, Jack Frost’s Winter adapts neatly to vertical play on both iOS and Android. Swipe interaction for the paytable and single-hand bet controls follow PG SOFT’s usual mobile-first pattern.

Licensing & transparency notes

According to PG SOFT, their portfolio is certified by BMM and GA laboratories and the company holds licences from the Malta Gaming Authority and Gibraltar. These claims refer to the studio level; always confirm game-specific RTP figures and rule sets within the paytable of the casino version you are playing.

Verdict

Jack Frost’s Winter is essentially PG SOFT’s most volatile Infinity Reels outing to date. If the prospect of a climbing multiplier with no hard reel limit appeals—and you have the bankroll resilience to match—the slot delivers plenty of white-knuckle spins. Casual winter-theme hunters, however, may find the variance snow-storm a little too frosty.
