Yeah...IDK honestly. FOR TEACHERS AND PARENTS: This game can be used as a educational rescource for math. And it gets harder the more you get right and also there are BOSS QUESTIONS. You can also choose what mode you want, Addition or Subtraction and also Multiplication. This can also be used to test your students on to showing what they already know. If you have Scratch 3.0 offline, please click "See Inside" and then "File" and click download to your computer. This will download a offline version of this game. Older kids or adults can use this to test their smarts.
