WILDS create sticky ICE FRAMES on all the grid positions they land on. When a WILD lands on an existing ICE FRAME, it adds a MULTIPLIER, incrementing x1 each time up to a maximum of x8. Up to x8 MULTIPLIER can be achieved on ICE FRAME: x2, x3, x4, x5, x6, x7, x8. ICE FRAMES stay on the grid during the current round and are removed when a new round starts.
