xMas Dwarfs Slot by Zillion Games

The Mystery symbol transforms into any symbol on the grid when it lands without forming a winning way - and unlike most Zillion games, it can become special symbols too, not just regular ones. A golden Mystery variant exclusive to this title adds another layer, likely offering enhanced transformations during Hold and Ring. With 1,024 ways across the 5x4 grid, even a single well-placed mystery transformation can cascade into multiple winning lines.

Hold and Ring triggers with 5 bonus coins plus a Boost symbol from the base game. The Boost collects and sums coin values into one combined payout, concentrating smaller amounts. Fill all 20 positions on the grid and the Grand Jackpot (1000x) completes the round. Major (100x), Minor (30x), and Mini (24x) tiers fill remaining spots.

Low-pay symbols are colorful Christmas baubles in red, blue, green, and gold - replacing the standard card values entirely. Four dwarf characters in festive outfits handle the high-pay side. Free Spins trigger from 3 Scatters, with the Boost symbol staying active for value collection but blocked from triggering Hold and Ring during the round. A background accumulation system guarantees the bonus eventually fires.
