    Book of Slingo - How to Play

    Betting in this game is fixed at 12 paylines.


    How to Play 

    Book of Slingo begins with 11 spins.

    Mark off numbers on the grid with the numbers on the reel to create Slingos.

    Complete Slingos to progress up the pay ladder.


    Symbols

    • Wilds - tick off any number in the column above
    • Super Wilds - tick off any number in the entire grid
    • Blockers - do nothing
    • Free Spins - awards an extra spin


    Free Spins Bonus

    The Free Spins Bonus is activated when three Bonus symbols appear.

    A symbol is randomly chosen to act as a special expanding symbol, which expands to cover the entire reel.

    This symbol pays as a Scatter symbol when it is involved in a win.

    The more Bonus symbols used to activate the Free Spins Bonus, the better the type of symbol selected.

    Number of Bonus Symbols
    Free Spins Awarded
    Type of Symbol Selected
    310Any
    410Any premium symbol
    510Eye of Horus symbol

    You can also trigger the Free Spins Bonus by completing eight or more Slingos.

    Once you complete eight Slingos, you can choose to activate the bonus or you may receive a cash prize instead.

    Landing extra Bonus symbols during the bonus will award additional free spins.

    Three, four or five Bonus symbols appearing during the bonus will award ten, 15 or 20 free spins respectively.

    Winnings achieved during free spins may be less or more than the cash exchange value.

     

    Extra Spins

    You can choose to buy extra spins at the end of the game if a better prize is available to be won.

    The current grid positions and the possible prizes available are used to determine the price of each extra spin - this will be displayed on the 'Spin' button.

    The price of an extra spin may be more than your base stake.

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

    You can control the extra spin limits in the 'Play Controls'.

    Super Wild symbols may be needed to award certain prizes in extra spins.

    It is not possible for Free Spins symbols to appear during extra spins.

     

    Free Games

    It is possible to play the base game for free at a predefined stake value.

    Any winnings achieved during the free game are collected at the end.


    Pending Games

    Incomplete games are completed after 24 hours using a random number generator.

    Any winnings achieved from the remaining games are automatically credited.


    Best Strategy

    According to the best strategy, Wild symbols and Super Wild symbols are always placed in the best position to increase the chance of creating a Slingo.

    If there are multiple positions offering the same chances, then the one included in the most Slingo lines is selected.

    If all available positions are included in the same number of Slingo lines, then one is selected at random.


    Book of Slingo RTP
