    How to Play Book of Slingo

    Create Slingos by matching whole lines of numbers on the grid with the numbers on the reel.

    The more Slingos you complete, the higher you move up the pay ladder.

    Book of Slingo begins with 11 spins but it is possible to win more during play.


    Wild Symbols & Super Wild Symbols

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

    Landing a Super Wild symbol allows you to tick off any number on the entire grid.


    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.

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

    Alternatively, you can choose to take a cash prize instead when you reach eight Slingos.

    The more Slingos used to trigger the bonus, the better the type of special expanding symbol chosen.

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

    10, 15 or 20 extra free spins will be awarded for landing three, four or five Bonus symbols, respectively.

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

     

    Extra Spins

    Extra spins may be available to buy at the end of a game if a better prize could be won on the next spin.

    The cost of each extra spin is calculated based on the current grid and the possible prizes that could be won.

    The 'Spin' button will display the price of the next spin.

    Note - extra spins may be more than your base stake.

    Extra spin prices are rounded to the nearest whole value, which could affect the RTP rate.

    It is possible to control the extra spin limits via the Play Controls.

    Free Spins symbols cannot appear during an extra spin.

    Super Wild symbols may need to land to award certain prizes.


    Free Games

    Free games of Book of Slingo will offer the base game for free at a predefined stake value, which is considered as a bonus cash stake.

    Any winnings will be collected at the end of the free game.


    Pending Games

    If a game is launched but not completed within 24 hours, the remaining spins are automatically played using a random number generator. 

    Any winnings are then automatically credited at the end of the game.


    Best Strategy

    The best strategy states that Wild symbols and Super Wild symbols will always be placed in the best position to increase the chance of a Slingo.

    Should multiple positions that offer the same chances be available, the position that is included in the most Slingo lines is chosen.

    If all available positions offer the same chances and Slingo lines, one will be randomly chosen.


    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.
