Retriggers Inside Bought Rounds

Not every game lets a purchased feature retrigger, and that detail changes the value of the buy quite a lot. Some providers cap extra spins when you pay for entry while leaving them uncapped on a natural trigger. Titles that keep retriggers intact after a purchase are listed with notes at https://thebonusbuyslots.com, which is more useful than it sounds. Reading the rules screen for that one line has saved me from a few disappointing purchases.
