What they are and where they come from
Free spins are slot rounds that do not deduct a stake from the player’s cash balance for that particular spin. The game still determines the outcome according to its rules, and a spin may or may not produce a winning combination. “Free” describes how the spin is funded; it does not guarantee a prize.
There are two main ways free spins work: they can be built into a slot or offered as a platform promotion. In a game, special symbols such as scatters or bonus symbols may trigger a sequence of extra spins. In a promotion, a platform grants spins for a particular game or period, sometimes as part of a campaign or task.
How they are triggered and what can change
When a game feature is triggered, the slot awards or applies the number of extra spins specified for that bonus round. Some games introduce additional features during the sequence, such as multipliers or special symbols; the details depend on the slot’s rules. Promotional spins, by contrast, may use a fixed stake per spin and may be limited to certain games. The number of spins, eligible games and expiry period therefore vary by offer.
The spins remain subject to the game’s randomness: a sequence may produce no prize, and free spins do not guarantee a win. Even when a game displays an RTP, that figure is a theoretical return estimate over many plays, not a prediction of what will happen in an individual session.
Winnings, conditions and checking the offer
It is useful to distinguish extra spins triggered within a slot from spins granted through a promotion. With promotional offers, any winnings may be credited as bonus funds and may be subject to wagering requirements, limits, eligible-game rules or an expiry date. Conditions differ, so check the specific terms before accepting an offer, including any rules for converting or withdrawing winnings. Do not assume that one promotion’s conditions apply to another.
