Bonus buy slots
The buy button skips the base game and drops you straight into free spins, usually for 60 to 500 times the stake. The return on a purchased round is typically a fraction of a percent above the standard figure, but variance multiplies: a hundred base-game spins and one bought bonus produce completely different balance curves. Germany and several other jurisdictions ban the feature, so locally licensed builds simply ship without the button.
How this slice was built
126 games out of the 996 in the catalog. The industry has no shared vocabulary for mechanics: studios describe the same thing in different words, so this list is assembled from a normalised set of spellings found in provider specifications — bonus buy, buy feature, feature drop (bonus buy), x-iter. If a game uses the mechanic but the provider never listed it, it will not show up here.
