What does Feature Buy mean in slots?

In slots, Feature Buy is a function that lets the player buy direct access to a special game mechanic without waiting for it to trigger naturally in the base game.

How does it work?

The player pays a fixed amount and enters the selected feature right away, whether that is a bonus round, free spins, a respin mechanic, or another feature mode. In meaning, Feature Buy is very close to Bonus Buy, but the term is a bit broader because it can refer not only to a classic bonus round, but to any separate feature inside the slot.
