The option suits a particular kind of session. Someone planning an hour of ordinary spinning, who enjoys the base game and wants the feature to arrive more often, gets exactly what they want from it; someone who would otherwise buy features outright gains little, because the boosted stake still requires waiting. Choosing double chance slots over a direct purchase is sensible when time is plentiful and the goal is more frequent, rather than immediate, access to the bonus. Players with only ten minutes are better served by the buy button.
