How to use the Cheeky Dice:
When starting the game, click on the top of the screen (above the dices) to be able to set the dice values. Then up the dices to your desired value by simply clicking on the dices and press "Set Dices" to store your value. Once this has been set, you can always throw the set number by clicking on the hidden button on the top of the screen again.
If you like to set a new value, simply restart the app.
