Christmas Plaza DoubleMax

Yggdrasil Gaming ships Christmas Plaza DoubleMax at 96% RTP by default; three lower alternates sit alongside it at 94%, 90.5% and 86% for operators who prefer them. It's built as a high-volatility game with a notably tight hit rate — 0.29% — so most spins come back empty while the game waits for a chain to properly connect.

Reels sit in a 5x3 arrangement with 25 fixed paylines. Landing a payline win triggers a chain reaction: the paying symbols vanish, a new wild fills one of the empty slots, and the grid refills itself from above. Every step of that chain doubles the multiplier attached to it, and that multiplier falls back to x1 as soon as a spin comes up empty.

Eight symbols populate Christmas Plaza DoubleMax's paytable overall. Four are Christmas-themed card suits worth 1x to 1.2x the bet for a full line of five, and four are higher-value objects — bottles, striped canes, snow globes and bells — worth 2x to 5x for the same length.

Scatters come as gift boxes, and three, four or five of them hand out 7, 10 or 13 free spins respectively. A 7 or 10 result isn't necessarily final, either — an optional gamble follows, essentially a coin flip between climbing to the higher spin count and losing the round outright. Once free spins are running, the multiplier no longer drops back to x1 between rounds — it either holds or grows — and because scatters can't reappear inside the bonus, there's no way to add further spins on top.

Where it's offered, a Golden Bet setting adds a 25% surcharge to each spin in return for double the odds of reaching free spins, and a straight Buy Bonus purchase — 100x the stake — drops players into 7 free spins immediately, gamble option included. Set against an ice-rink plaza of skyscrapers, drifting snow and string lights, Christmas Plaza DoubleMax caps its win potential at 20,000x the stake, with bets running 0.20 to 50 per spin.
