No lines, no ways: 8 or more symbols of a kind in any position on the reels count as a winning combination.
With the Cascade Feature, symbols forming a winning combination disappear and are then replaced by other symbols coming from above.
The up to x500 win multipliers can appear on the reels during the base game and the Free Games. The multipliers multiply the total win at the end of the cascade sequence. If several multipliers appear in the same spin, they are summed up.
