THEBONUSBUYSLOTS

The term comes from Relax Gaming, which uses it as the brand name for its purchase button across the studio’s catalogue. It gained recognition largely through the Money Train series, where the option let players skip straight to the respin round that made the games famous. In feature drop slots from this studio, the wording appears on the interface itself rather than in casino marketing, so the label is consistent from one title to the next. Other providers describe the same mechanic under different names.
