Mammoth Legend at JACK Thistledown Racino - AP Guide

On Mammoth Legend, landing a bonus symbol fully in reel five lets you pick a prize from five coins. One coin holds the Volcano Bonus; the other four hold credit prizes. Pick a credit prize and that coin is removed, so the next bonus offers only four coins — and when just one coin is left, your next pick is forced to be the Volcano Bonus.
