The terms free bet and free spins both appear regularly across online casino platforms, and they’re often grouped together as if they mean the same thing.
They don’t. If you’ve ever wanted to try your chances at an online casino and noticed both listed under promotions, understanding the difference between them is straightforward once the mechanics are explained.
What is a free bet?
A free bet is a promotional credit that lets you place a wager without using credits from your own account. The operator covers the stake.
If the bet loses, you don’t lose anything from your balance. If it wins, only the profit is returned to you. The original stake is not paid back.
For example, 10 coins placed as a free bet on odds of 3/1 would return 30 coins in profit if successful, not 40. The 10 coin stake itself is not included in the payout.
Free bets are most commonly associated with sportsbook activity, but some online casino platforms offer them for use on specific casino products.
Terms attached to free bets typically include minimum odds requirements, eligible markets, and an expiry window, often seven to 30 days from the point they’re credited.
What are free spins?
Free spins are promotional credits applied specifically to slot games. Rather than covering a wager across different markets, free spins give you a set number of rounds on a designated slot title. The value of each spin is fixed by the operator, and you have no control over that amount.
Any winnings from free spins are not automatically withdrawable. They’re subject to wagering requirements, which means you need to place a certain value of bets before those winnings can be withdrawn.
As of January 2026, UK-licensed operators are capped at a maximum 10x wagering requirement on bonus funds and free spin winnings.
How they differ?
The core difference is in what they apply to and how winnings are structured.
Free bets cover a wager on an eligible market, which might be a sporting event or a specific casino product, depending on the operator’s terms. Free spins apply only to slot gameplay on the designated game or games listed in the promotion.
The payout structure also differs. A free bet returns profit only, with no stake returned. Free spins generate winnings that are then subject to wagering requirements before they can be withdrawn. In both cases, neither format guarantees any particular outcome. Results are determined by chance.
What to check before using either?
Before using a free bet or free spins offer, it’s worth checking the full terms attached to that specific promotion.
For free bets, look at the eligible markets, minimum odds, whether the bet must be placed as a single or accumulator, and the expiry date.
For free spins, check which game or games are eligible, the value per spin, the wagering requirement on any winnings, any maximum win cap, and how long you have to use the spins and meet the requirements.
On wagering contributions, it’s also worth noting that not all games count equally. Slots typically contribute 100% toward meeting a wagering requirement, while table games such as Blackjack or Roulette often contribute at a lower rate, sometimes as little as 10 to 20%.
