If you’re tired of spinning endlessly waiting for the free spins round to trigger, Bonus Buy slots are your shortcut to instant action. In 2025, more game providers are releasing titles with Bonus Buy features—allowing players to pay upfront for immediate access to free spins or other exciting bonus rounds.

In this guide, we’ll explore the best online slots with Bonus Buy functionality, how it works, and where to play them legally and securely.

What Is the Bonus Buy Feature in Slots?

The Bonus Buy feature allows players to purchase direct access to a slot’s bonus game (usually free spins, hold-and-win, or multiplier rounds) instead of waiting for it to trigger naturally. This option is available in many modern slots for a fixed price—often ranging from 50x to 200x your base bet.

Why Buy the Bonus?

• Instant excitement without waiting for scatter symbols
• Chance for bigger wins via multipliers and features
• Time-saving for players who want direct bonus action

How Does Bonus Buy Work Technically?

When you select the Bonus Buy option, your stake is multiplied by a fixed value (e.g., 100x). The game then immediately launches the bonus round without requiring a base game trigger. This doesn’t change the underlying RNG—it just fast-forwards the gameplay.

Example:

• Your bet: $1
• Bonus Buy Cost: 100x = $100
• You instantly start the free spins round without landing three scatters
