Key takeaways
- Six of seven slots have free spins.
- Triggers: three or four scatters.

Short answer: Fluffy Favourites gives the most free spins (up to 25, tripled); Gates of Olympus gives 15 with cumulative multipliers; Book of Dead's 10 hinge on one expanding symbol.

Three kinds of feature
Collectors

Expanding symbol
Book of Dead: all or little, depending on the symbol drawn.
How often features land
Developers seldom publish trigger rates, and we do not quote unverified ones. As a rule, high volatility features are infrequent enough that a hundred spins may not see one.

Played at your stake
Feature spins use the stake of the spin that triggered them. Trigger Book of Dead's ten spins on a 20p bet and each free spin is a 20p spin you did not pay for. That is why the triggering stake matters far more than how long you have been playing.
