Gameplay and Bonuses

The central highlight of Christmas Boom is its multi-stage respin game that blends Hold and Win style mechanics with reel enlargement:

Boom Snowglobe Trigger: When you land six or more Boom snowglobe icons anywhere on the grid during regular play, the main feature activates.
Expanded Grid Mechanics: At the start of the feature, the grid instantly expands from its base 5x3 configuration into an impressive 7x5 layout. This expansion opens up two extra reels and additional symbol spots, providing plenty of space for new symbols to land.
Respin Counter: The triggering snowglobe icons lock into place, and you receive three respins. Each time a new snowglobe, prize coin, or jackpot token lands, it locks on the reels and resets the respin counter back to three.
Fixed Jackpots: Special jackpot tokens can land throughout the feature round. These include the Mini Jackpot (20x), Minor Jackpot (50x), and Major Jackpot (150x). Filling all positions across the expanded grid awards the top Grand Jackpot worth 3,000x your spin value, helping players push toward the maximum overall reward of 4,000x.
Play the Feature: In select versions, players who want instant access can choose to play the feature directly and jump straight into the expanded respin grid.

Our Verdict

Christmas Boom brings cozy holiday warmth together with high-volatility action. The visual design captures classic winter charm with glowing ornaments and gentle snowfall animations.

This extra space makes chasing locking coins and fixed jackpots enjoyable and suspenseful on every respin. It is an entertaining seasonal choice for players who appreciate expanding layouts and jackpot potential.
