Feature sequence and rule differences

Matching stacks on the first two reels lock in place for a respin. Their retained positions distinguish that sequence from a fresh ordinary spin.

Understanding the rules

A held position remains for the stated feature sequence. This is different from an ordinary new spin, which need not retain that position. The counter, reset event and ending condition must be read together. Retaining a symbol does not by itself guarantee a winning combination.
