Crystal Quest Frostland slot by Thunderkick is a high volatility game with a 6x4 grid, 4,096 ways to win, and 15,000x the stake winning potential. This is the third installation in the provider's popular Crystal Quest series following the adventures of a wide-eyed explorer Gemma.
The slot's special features include Massive Symbols, avalanches, free spins, and a progressive multiplier. The avalanche system is triggered by a winning combo of 3 or more symbols and boosts the player's chances of landing bigger rewards. Unsurprisingly, this feature has been very popular among casino streamers but the provider took things up a notch in this release and tied it to a progressive multiplier. Starting at x1, the multiplier increases by one level whenever the avalanche feature is triggered.
Any symbol except the scatter or wild may appear as Massive Symbols in the base or bonus game. When active, Massive Symbols land in 2x2 or 3x3 size, crushing all symbols beneath them. Landing at least 3 Scatters will trigger 12 Free Spins. During the bonus round, a progressive multiplier doesn't reset between spins. Also, it comes with the Wild Explosion feature which gets activated on a dead spin. All Wild symbols on the reels explode, destroying all symbols horizontally and vertically (except scatters), triggering an avalanche.
