Everything you wanted to know about Bonus Buy

Published on 02.01.2026. Last updated on 02.01.2026

Spinomenal is one of a few makers to build the Bonus Buy feature into almost every video slot. Its logic is straighforward. Instead of waiting for nobody knows how much, you can trigger free spins or another feature immediately. The RTP of your bonus rounds will stay the same as in the main game.

How to activate the Bonus Buy?

Step 1: Find where the feature is triggered in the UI.

Tap ‘Buy’ (pointed with the red arrow). Other providers can name this button differently. Spinomenal usually places it near the Spin button but you can also locate it at other places.

Step 2: Set your bet for the free spins.

You can choose the bet size for the upcoming free spins. Your choice will determine the cost to be debited from your account. Let’s take a look at the screenshot above. If you pick a $0.25 bet per spin, the game will take $9.75 from your balance.

Once you approve the purchase, the amount you’ve agreed to is deducted from your balance and the bonus round starts immediately. It finishes when the set number of free spins expires. You can often extend the feature if the required number of scatters (normally, three) land on the screen (if this is envisaged by the game rules).

How much does the Bonus Buy cost?

It depends on the Bonus Buy slot. Look at the above picture, taken from Majestic Santa. As you can see, you must pay x39 times your total bet. In return, you will get 10 to 40 spins, depending on the outcome of the bonus wheel spin. Other Spinomenal slots have a different price, e. g. x102 in Chase the Fruits and x106 in Super Miner.

What kind of features can I buy?

All Spinomenal slots that I’ve seen so far offer free spins exclusively. However, this does not mean Spinomenal has it only this way. Maybe I will encounter other bonuses triggered by the Bonus Buy tool as I continue reviewing the video slot collection.

Free spins unlocked via the Bonus Buy are sometimes augmented by minor bonuses. For example, Book of Sirens offers 10 FS with a random expanding symbol at x104.

In some games, the feature is more flexible than usual. Cyclops Unchained offers to pick 10, 25 or 100 FS at x2 per spin instead of a fixed number of FS.

Summary: Should I buy a bonus or not?

I believe this tool is for guys who like taking risks because the expenses on buying the feature are usually not paid off. Experience makes it plain that a player does not normally have enough free spins to generate money that would cover the cost of buying the bonus. So, as a rule of thumb, you had better steer clear of using it.
