Same number in other versions
Brain Test versions can reuse the same level number with a different puzzle. If the screenshot or question does not match your game, switch to the same number in another version or use the nearby level links.
Strategy guide
- 1.Ignore the pictures; focus on the numbers 1, 2, 3 and the instruction to add symbols;
- 2.Insert a plus between 1 and 2, and a minus between 2 and 3 to create 1+2-3;
- 3.Treat the level as a math problem, not a visual spot-the-difference challenge.
Common mistakes
- 1.Counting visible differences in the pictures instead of interpreting the question as a math puzzle;
- 2.Trying to spot differences in the images rather than focusing on the equation 1 2 3 shown;
- 3.Overlooking the need to insert plus and minus symbols between the numbers to form a correct equation.
