Slots with extra free spins

Mechanically, this facet gathers games where the free spins round can be extended mid-play – typically by landing extra scatters, counting symbols on a meter, or triggering special retriggers. On paper this means more time in the bonus round, and the numbers in the catalog show the feature is almost always paired with multipliers and avalanche/cascade.

RTP ranges between 95 % and 97,3 % with a median of 96,3 %. Four titles are missing RTP. Volatility is predominantly high; 23 of 31 are marked high, while only three are in the middle. This points to bonuses that can grow via extra rounds but which also fluctuate in outcome.

What qualifies for the list

A game falls into this category when the feature list includes Extra free spins in addition to a regular free round. These can be explicit retriggers, extra spin bundles from collecting symbols or a bonus trail that adds spins along the way. In practice it plays closely together with Free spins, Multiplier and Free spins multiplier, which also dominates the selection. Avalanche and cascade occur almost as often, which gives more symbol drops per bet and therefore more chances to hit the expansions that extend the round.

Providers and profile

The selection is spread across many hands. Pragmatic Play delivers five titles, Barbara Bang three, while Play'n GO and Mount Olympus provide two each; the rest are single contributions. That yields variation in reel sets and win models, but in practice many converge on 6x5 setups and Pay Anywhere/Scatter Pays. The newest entry is Supreme of Olympus fra 27. maj 2026, mens den ældste registrerede i denne familie er Royalty of Olympus Extreme fra 15. april 2025. The combination of multiple providers and a tight 2025–2026 timeframe explains why the designs resemble each other across titles, but the implementation of extra spins varies.

RTP, volatility and what it means

With a range of 95–97,3 % and a clear overweight of high volatility, the play profile is skewed toward the bonus chase: shorter base games, longer bonuses when they finally hit. Exceptions exist: 97,3 % in Gates of Olympus Roulette is a top tier in this niche, while several titles sit close to 95 %. Some games do not disclose reel sets or ways to win, so here it is more relevant to assess overlap with Cascade/Avalanche og the multiplier types – they are the actual drivers for how much extra free spins can grow in value.

Three markers in the catalog

Olympus Wins Super Scatter stands out with a cap of 100000x and a combination of scatters, cascades and multipliers, which in the provider's game data are stated to be able to branch the free round via retriggers. Rise of Olympus 1000 goes the same direction with 60000x and both an RTP range and Scatter Pays, which on paper gives flexible setups from casino to casino. For another approach, Chronicles of Olympus Assembl'em shows a 5x4/1024-way model with Cash Collector and fixed jackpots, where extra spins are tied to collection and bonus rounds rather than pure cascades. As a contrast, 1000 Olympus Rivals Hold & Win uses Hold & Win together with extra spins, which lands more in the middle of the field on volatility and payout cap.

The list can be used as a shortcut to titles where the free spins length is not static. If you're focused on high risk and big jumps, the High Volatility and Biggest max-win collections point to the majority of the selection. If you instead seek transparency in the payout rate, Top-RTP is relevant; otherwise the absence of RTP on some games can be a dealbreaker. Thematically most of it sits in gods and Olympus, but mechanically the spread is real – especially when Random Multiplier is mixed in.
