Bonus buy slots: what you pay for the skip button

What it is

In some slots a menu lets you buy the feature directly. For example, the provider's page for Gates of Olympus 1000 lists a bonus buy in the base game that costs 100 times your bet and triggers the free spins round. On a $0.50 bet, that is a $50 purchase. On a $2 bet, it is $200.

The maths

You are paying for the feature up front, and the average return of the bought round is designed to be close to the game's overall RTP, though providers can set buy-specific RTPs that differ. Buying does not give you better odds; it concentrates your spending into a single large event. A single buy on a high-multiplier game can pay far more or far less than what it cost. The average is a long-run figure and bonus rounds are high-variance.

Say you set aside $100. At 100x a $0.50 bet costs $50, so you get two buys. Two high-variance outcomes are a very small sample. Without the buy, the same $100 gives 200 base spins, which show up as many small outcomes.

Where it is restricted

• Some operators and jurisdictions disable bonus buy.
• Many bonus terms ban or exclude bonus-buy play while wagering, and a breach can cost you the bonus and winnings. Read RTP and the casino's terms.
• Some games do not offer a buy at all, and we only mention a buy when the provider's page lists one.

A sensible approach

Treat a buy as a spend, not an investment. Decide the amount in dollars before you open the menu, keep it a small part of your budget, and stop when it is gone. If buying makes you chase losses, turn it off. Casinos usually let you set limits that include buys.

Questions to ask before you buy

1. What does the buy cost in dollars at my current stake?
2. Is the buy allowed under any bonus I have active?
3. How many buys can my budget cover? If it is fewer than three, the result will be dominated by luck.
4. Would I be as happy playing the same money as base spins?

If the honest answer to the last question is no, the buy is paying for speed, not value, and that is a legitimate choice as long as you know it.

Why operators and bonuses restrict it

Because a buy lets a player turn a bankroll into feature rounds quickly, operators often exclude it from wagering. A typical clause says bets placed through a feature purchase do not count toward the requirement, or that using it voids the bonus. Check this before you open the menu with bonus funds active, and use cash balance for a buy if you are unsure.

A budget rule for buying features

Before you press buy, check what fraction of your session budget a single purchase takes. At 100x the bet, one purchase on a $1 stake costs $100. A simple rule is to never let one purchase exceed a small share of what you set aside for the session, because a bought round can return less than it cost. If a purchase would take most of your budget, lower the stake or skip the feature.
