Every mechanic has its own sequence.
A held position can stay visible while other positions change. A cascade can remove a qualifying group and bring fresh symbols into the same field. A Wild can substitute under that game's stated rules. A sealed choice waits for your selection before the recorded feature is completed.
These descriptions explain presentation and controls; they are not promises of an award. Read the actual game's in-player rules and use its public animation preview. A feature is part of that game's full recorded round, and nothing on this page changes its probabilities.
