How to Play Book of Slingo
Match numbers on the grid with those on the reels in order to form Slingos in this game.
You will progress further up the pay ladder as you complete more Slingos.
When you play Book of Slingo you will have 11 spins initially, although you are able to win more during the game.
Wild symbols allow you to mark off any number on the grid in the column above.
Should a Super Wild symbol appear, then you have the option to mark off any number on the whole grid.
You will receive an additional free spin if a Free Spins symbol is displayed.
Free Spins Bonus
The Free Spins Bonus is activated when three Bonus symbols land on screen.
One symbol is chosen at random to become the Special Expanding symbol, and this subsequently expands and covers the entire reel.
Special Expanding symbols will be paid out as a Scatter symbol across win lines.
If you unlock the Free Spins Bonus with a greater number of Bonus symbols, your Special Expanding symbol will be a more valuable one.
|Bonus Symbols||Free Spins Awarded||Selected Special Expanding Symbol|
|4||10||Any premium symbol|
|5||10||Eye of Horus symbol|
It is also possible to initiate the Free Spins Bonus by winning a minimum of eight Slingos.
Should you complete eight Slingos, then you will have the option to accept a cash prize, as opposed to triggering the bonus round.
You can win more free spins while you are playing the Free Spins Bonus, and to do this you must land at least three Bonus symbols.
|Extra Bonus Symbols Landed||Extra Free Spins Awarded|
During the Free Spins Bonus, any winnings you accumulate can be higher or lower than the cash exchange value.
When you game has ended you may have the option to purchase extra spins, if you could potentially scoop a better prize on your upcoming spin.
The price of each extra spin depends on your position on the grid, as well as any potential prizes.
The price of the upcoming spin will be displayed on the 'Spin' button.
It's possible for the price of any extra spins to exceed your base stake.
Prices of these extra spins are rounded to the nearest whole value, and as a result this may impact the RTP rate.
You can control extra spin limits via the Play Controls.
On any extra spins you buy, Free Spins symbols will not be displayed.
For specific prizes to be triggered, Super Wild symbols may be required to hit.
When you are awarded any free games in Book of Slingo, you will be offered the base game for free at a predefined stake value. This is therefore classed as a bonus cash stake.
At the conclusion of your free game, any winnings you achieved will be collected.
If you start a game but fail to complete it within a 24-hour period, any spins you have left will be played out using a random number generator.
Any winnings are then automatically credited when the game has concluded.
Slingo Best Strategy
Your optimal strategy in this game is to place Wild symbols and Super Wild symbols in the best position, thus improving your chances of completing a Slingo.
If a number of positions are available and give you the same chance of winning, it will select the position that features in the highest amount of Slingo lines.
If all available positions offer the same chances and Slingo lines, it will randomly select one of them.
Return to Player
