How free spins work in online slots
The basics behind a popular slot bonus.
Free spins are where a slot’s most distinctive features appear. They’re a common bonus feature in online slot games, and can come in the form of standard free spins, retriggerable free spins, feature-enhanced free spins and more.
They allow the reels to spin a set number of times without using additional credits from the player’s balance. Found in many titles at licensed online casinos in Ontario, free spins add variety to gameplay while keeping the same core mechanics of the slot. Here’s how free spins typically work in online slots at Betty:
What are free spins?
Free spins are extra rounds in a slot game that do not require an additional wager. They are usually activated by landing a particular combination of symbols, often called scatter symbols. During these rounds, the game utilizes the same reels and paylines as the base game, but may incorporate additional features, such as multipliers, expanding reels, or special symbols.
Free spins stand out because they change the pace of the game. They create a distinct gameplay section that feels different from standard spins, whether through added features, animations, or a different reel format.
Common types of free spins
- Standard free spins: a fixed number of spins using the same reel setup as the base game.
- Retriggerable free spins: additional free spins can be earned during the bonus round.
- Feature-enhanced free spins: spins that include multipliers, sticky wilds, or expanded reels.
How free spins are triggered
The exact trigger conditions vary by slot. The most common way is landing three or more scatter symbols in a single spin. Other games may use bonus wheels or in-game features that award a set number of spins. Because each title is different, the rules and number of spins vary from game to game.
Standard features during free spins
While every slot is unique, free spin rounds often introduce mechanics that differ from standard play. Examples include:
- Multipliers: certain games apply a multiplier during the free spin round.
- Sticky wilds: symbols that remain in place for the duration of the feature.
- Expanded reels: some titles increase the reel size or paylines during free spins.
These additions alter the gameplay, but do not impact the randomness of outcomes, which are always determined by the game’s random number generator (RNG).
Do the wagering requirements influence how often free spins occur?
No, the frequency of free spins is determined purely by the RNG and the mathematical design of the specific slot game.
Wagering requirements are a promotional condition set by the casino (like us) on winnings derived from a bonus (like a welcome offer of 50 Free Spins). They have zero impact on the game’s core mechanics, the RNG, or the statistical likelihood of landing scatter symbols to trigger the in-game free spins feature.
Do free spins use the same RTP as the base game?
Yes, free spin bonus features are fully included in the game’s overall RTP calculation. They may feel different from standard spins, but they are part of the same mathematical model.
Can I win the progressive jackpot during a free spins round?
This varies from game to game, but typically, yes. Many progressive jackpots are triggered at random during any spin, including free spins. In others, the progressive jackpot is only accessible via a separate, randomly triggered jackpot bonus game (often a spinning wheel or pick-and-click screen). Check your favourite game’s features to learn how it handles free spins and jackpots.
How does the theoretical Return to Player (RTP) account for the free spins bonus?
The RTP percentage advertised for any slot is calculated over millions of simulated spins and includes all potential winnings, including those from the free spins bonus. In fact, in highly volatile slots, the free spins feature often accounts for a significant percentage of the game’s total advertised RTP.
This is why the base game might feel tight. The mathematics are reserving a large portion of the game’s total payout for those high-reward bonus rounds. You need the free spins to achieve the theoretical long-term RTP.
