Buy freeplay in slots
If you like taking risks, you do not need to wait for the bonus function. There are many slots in which you can use bonus features at any time simply by paying for them. If you buy feature slot in casino, you are not guaranteed to win but such an opportunity exists and this is good anyway.
Different developers have an offer to buy feature games in slot, but they call these features differently. Big Time Gaming calls it Feature Drop, Quickspin — Hi Roller mode. Blueprint Gaming, Yggdrasil and other developers offer to buy freeplay in slots games as well.
Buffalo Rising and Viking Unleashed by Blueprint Gaming
Buffalo Rising - buy freeplay in slot and choose from several options. Either a certain number of FS and multipliers, or a random choice when you can get up to 15 spins and up to x10 multipliers.
Vikings Unleashed is basically similar to Buffalo Rising. But you can not only buy FS, but also take a chance to increase their number, as well as a multiplier. There is a special gamble feature for this. Choose it and see if you are lucky or not.
White Rabbit, Extra Chilli, Book of Gods by Big Time Gaming
White Rabbit and Extra Chilli are the two offspring of BTG. The company came up with MegaWays mechanics and sold it to the aforementioned Blueprint. Perhaps the idea to buy feature slot was an addition to the acquiring, as White Rabbit which appeared long before Buffalo Rising and Vikings Unleashed, already had such a function.
In the White Rabbit slot, 15 FS will cost you 100 bets.
Extra Chilli - the bonus costs 50x of the bet. The bonus game principle is similar to Vikings Unleashed. An initial value is given, and then the player can try to increase the number of spins up to 24 FS. During the bonus round, additional spins will be awarded and the multiplier will be increased.
Book of Gods is most likely one of the least known BTG slots. And this is not surprising. They do not use their famous MegaWays here which makes the slot seem more ordinary. From 15 to 25 free spins can be bought for 80 bets. During free spin mode, one of the expensive symbols can expand to the entire reel.
Joker Strike by Quickspin
Joker Strike is a slot machine that was created based on Second Strike. One of the few differences was that the Hi Roller mode was added to Joker Strike which allows you to buy five spins with additional features for €20, €30 or €50.
The higher the cost, the more profitable opportunities.
Slots from Betsoft
Faerie Spells offers to buy feature slot in online casino 25 free spins for 86 bets. During free spins, there is an opportunity to win one of four jackpots. Moreover, the symbols in the bonus round are completely different than in the main game.
Chilli Pop is a fairly simple but fun online slot. You can buy here 10 FS. The Golden Owl of Athena offers to buy up to 20 free spins with a random special symbol that can be expanded to the entire reel and pays regardless of location.
You can buy bonus feature slot if this function is available in the game but the price will be different for each of them depending on how profitable re-spins may turn out.
