When Sumo symbols land next to each other they are stacked and receive a multiplier depending on their number. When Sumo adds you receive a respin. That Stacked Wild moves sideways between respins and can collect even more Sumos.

When opposing Sumo Stacked Wild symbols face each other they fight. The stack with the higher multiplier always wins and takes the strength of the opponent. Stacked Wilds with the same multiplier just merge.
