It works the same way Whole Number and Tens Wishball challenge game works. You can read the instruction at the start and you will be ready to go. You just have to do some math to get the target number. Press the Wishball button to get a random number, choose one of them to subtract until you get the target number. When you think it’s very low between 1 to 9 or (10, 20, 30,…… 90), you can use W icon to get the number.
