A game for clever heads

1+2=3. Sounds easy to you, right? Then play this game and prove your math skills. It might be all about numbers 1, 2, and 3, but keep in mind that the clock is ticking!

Can you outsmart a 6-year-old?

In this game, you only need three numbers: 1, 2, and 3. It’s all about adding and subtracting these three digits. But that’s not all. Even your answers will always be 1, 2, or 3. Sounds easy, right? Not so fast. There is a catch: You only have 3 seconds to give the correct answer. Can you calculate that fast or do you have to guess? The more problems you solve, the harder it gets. Test how fast you can add 2 and 2 and prove to everyone that you are up to the task! Play 1und2 for free and prove that you are smarter than a 6-year-old.
