Wild Symbols & Super Wild Symbols
Wild symbols let you tick off any number on the grid in the column above.

Blocker Symbol
Blocker symbols do nothing.
Free Spins Symbol
A Free Spins symbol appearing will award an extra spin for free.
Free Spins Bonus
Three Bonus symbols appearing on the reel will trigger the Free Spins Bonus.
One symbol is randomly selected to be a special expanding symbol, which will expand to cover the whole reel.
Special expanding symbols pay as a Scatter symbol across win lines.
The more Bonus symbols used to trigger the bonus, the better the type of symbol chosen to be the special expanding symbol.
Bonus Symbols | Free Spins | Type of Symbol Chosen as Special Expanding Symbol |
|---|---|---|
| 3 | 10 | Any |

The Free Spins Bonus can also be triggered by winning at least eight Slingos.

Extra free spins can be won by landing additional Bonus symbols during the Free Spins Bonus.

Any winnings from the Free Spins Bonus can be above or below the cash exchange value.
