Welcome to a different and creative way to think about math!

?? + ?? = 5
?? x ?? = 18
?? x ?? + ?? = 36

Can you find a solution when already given the answer?

Most math games give you a couple numbers and ask you to find the total value. SCRATH does the exact opposite! Given that total value, can you use the nine numbers you are provided to determine those couple numbers?

SCRATH has game modes for people of all ages and abilities. You can play anything from Beginner Mode, which asks you to find the two numbers between 1-9 that you can add to equal a given value, to Ultra Mode, which asks you to find the four numbers ranging from 1-50 that you can multiply, add and subtract to equal a given value, to even a Custom Mode, which allows you to set your own preferences! Does this sound easy? Maybe. Does this sound like a challenge? Definitely.
