FREE SPINS – Land 3 or more Bonus symbols to trigger the Free Spins round. Whenever Mystery symbols land on the reels during this round, they all transform into the same paying or Wild symbol. After each spin all the Mystery symbols are collected and added to the treasure chest, with the number of Mystery symbols in the chest being shown on the outside. Once the Free Spins round ends, all the Mystery symbols will come back onto the reels in random positions.
If more than one Mystery symbol lands in the same position, the multiplier will increase by 1x. This multiplier applies to all winning lines that pass through the symbol, and if more than one multiplier passes through it, the multipliers will add to each other.
For every 5 Mystery symbols collected, the treasure chest will award up 1, 2, or 3, additional Free Spins at random.
