What Are Free Spins Bonuses?

Free spins are one of the most common bonuses offered by online casinos. With a free spins bonus, you receive a certain number of spins on a specific slot machine, each worth a set amount of money. Those amounts are usually 0.10 euros per spin. Free spins can either be given automatically to you when you register at a casino, or they can be credited to your account once you have deposited money into your casino account.

No deposit bonuses offer free spins without requiring a deposit of money into your casino account. These bonuses usually have restrictive terms and low spin values. Deposit bonuses require a deposit into your casino account prior to receiving the free spins, which is why the terms are less restrictive.

The winnings from free spins are not usually withdrawable immediately. Instead, the winnings must be wagered a certain number of times in order for the casino to release the bonus as real money to you.

Why Bonus Terms Matter More Than the Headline Number

The number of free spins that a bonus offer might advertise as being available to you, such as 300, 100 or 50 spins, tells you nothing of use about the bonus offer. What matters is the terms of the bonus offer.

Wagering requirement — the number of times that your winnings have to be wagered out before you can withdraw them. For example, a wagering requirement of 35x on a bonus of 10 euros means that you have to wager 350 euros. A lower wagering requirement is better.
Maximum cashout — the maximum amount of money that can be withdrawn from a bonus. This is usually with no deposit bonuses.
Expiry window — the expiry window during which you have to claim your spins and wager your bonus money. If the window is missed, the bonus is forfeit. This is usually 24 hours for no deposit bonuses.
Max bet per spin — the maximum amount that you can bet on a slot machine spin while on a bonus. Going over this amount will void your bonus money and winnings.
Game restrictions — the specific slots on which your bonus spins will be given to you. Bonus money from winnings usually has game restrictions, too.

Each of the terms above are discussed in detail in the bonus guides on this website.
