The 6x6 cluster payouts grid in Buster's Bones, a medium to high volatility canine wild west game from NetEnt, has Avalanche Wins. Buster transforms into a walking wild that gathers and creates wilds out of bones, increasing his wild multiplier in the feature. In the bonus round, you get more of the same and an additional non-resetting Buster Wild Multiplier. The maximum win is 973 times your bet.
There are numerous thrilling additional elements in Buster's Bones. The highest-paying symbols are three dogs with green, blue and purple wooden backgrounds, and you must line up at least five identical symbols vertically or horizontally anywhere on the field to win a cluster. With the Avalanche feature, winning symbols are eliminated and replaced with fresh or old symbols that descend from above. As long as you keep winning, this cycle will continue.
During the Buster's Bones feature, wild symbols come into play and substitute for pay symbols to help complete and/or enhance wins. The feature must be activated with at least one Bone Special Symbol and a Buster Special Symbol in view. The corresponding places go wild as a result of Buster moving about the grid to collect any bones in sight.
Buster himself also functions as a wild symbol, and when he appears, the win multiplier is increased by the value of the accumulated bone symbols. The win multiplier is utilised when the Buster Wild contributes to a victory while pausing the bone gathering. When the feature is over, Buster and the multiplier vanish, but it is always possible for it to occur again on a subsequent spin.
When two free spins scatter and one Buster Wild appear in the same spin, the Bonus Round begins, awarding you eight free spins. The Buster Wild roams the area gathering bones that make the surrounding areas wild while also increasing his own wild multiplier. For the duration of the bonus round, the multiplier doesn't reset, and landing 1 or 2 scatter symbols on the same free spin, respectively, awards you with +1 or +3 extra spins.
