Pay 50% more per spin for better feature odds while wins still use the base bet. Frequency up, paytable unchanged - plan before you toggle it.
Boost+ is a base-game toggle on Holly Jolly Bonanza 10,000. Switch it on between spins. Each spin costs 50% more. Feature-trigger chances improve. Win sizes still resolve on the base bet.
Example: base 1.00 with Boost+ costs 1.50. A 5x result still returns 5.00, not 7.50. You are buying frequency, not a higher paytable.
Use Boost+ when you want more free-spin entries and can accept a hotter burn. Leave it off for longer base sessions or when you are still learning the grid in demo (Boost+ will matter once the real build is live).
Combined with a 100x bonus buy, stake planning gets steep. Decide the Boost+ policy before you open the cashier, not after a cold streak.
