Enjoy the Slingo version of the popular Book Of franchise for a chance to win up to 500x your bet!
You can play Book of Slingo from just 10p per spin.
Betting in this game is fixed at 12 paylines.
How to Play
The game begins with 11 spins.
Match numbers on the grid with ones on the reel to complete Slingos and move up the pay ladder.
Wild Symbols & Super Wild Symbols
When a Wild symbol lands on the reel, you can mark off any number in the column above.
Super Wild symbols let you mark off any number in the entire grid.
These symbols do nothing.
Free Spins Symbol
An extra spin is added for free when a Free Spin symbol lands.
Free Spins Bonus
The Free Spins Bonus is triggered when at least three Bonus symbols appear.
At the beginning of the free spins, a symbol is randomly chosen to be a special expanding symbol.
This special symbol will expand to cover the whole reel and pays as a Scatter symbol across win lines.
The symbol chosen to be a special expanding symbol is dependent on the number of triggering Bonus symbols.
Number of Bonus Symbols Used to Trigger Free Spins
Number of Free Spins Awarded
Type of Special Expanding Symbol Chosen
|5||10||Eye of Horus symbol|
Achieving at least eight Slingos will offer the option to trigger the Free Spins Bonus or take a cash prize.
The more Slingos used to trigger free spins, the better the special expanding symbol.
Landing three, four or five Bonus symbols during the bonus will award 10, 15 or 20 extra free spins, respectively.
Any winnings from the Free Spins Bonus can be above or below the cash exchange value.
You may choose to buy extra spins after each game if a better prize is available to be won on the next spin.
The price of each extra spin depends on the current grid positions and potential prizes available.
The price of the next extra spin will be shown on the 'Spin' button and may be more than your base stake.
Extra spin prices are rounded to the nearest whole value, which could affect the RTP rate.
The Play Controls will enable you to control the extra spin limits.
Free Spins symbols cannot land during extra spins.
Super Wild symbols may need to land for certain prizes.
In the event of a free game of Book of Slingo being awarded, the base game will be offered for free at a predefined stake value.
Any free game winnings will be collected at the end.
The free game is considered as a bonus cash stake.
Any games not completed 24 hours after launch are automatically played out with a random number generator used to make player decisions.
Winnings are automatically credited when all remaining spins have been played out.
The best strategy states that the positions of Wild symbols and Super Wild symbols will always increase the chance of a Slingo.
If more than one position of the same standard is available, the position included in the most Slingos is chosen.
If both available positions are equal in potential value, one is randomly selected.
Return to Player
Return To Player (RTP): 95.00 - 96.38%.
The expected return is the amount we pay out to players relative to the amount of wagering on the game.
For example, if we take £100 of wagers we will, on average, pay out £95.00 - £96.38 of wins.
