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.
Why this works

Strategy guide
- 1.Rub your finger firmly on the left choice until it fades away completely;
- 2.After rubbing the left choice, wait for new choices to appear before making a selection;
- 3.Focus on the left choice first, as rubbing it is the key to unlocking the correct answer.
If it did not work
- 1.If the new choice does not appear, keep rubbing the left side longer.
- 2.If you tap instead of rub, the first option may remain in place.
- 3.If the puzzle resets, repeat the removal step before making a selection.
FAQs

Common mistakes

- 2.Trying to drag the left choice off-screen instead of rubbing it to reveal new options;
- 3.Assuming the right choice is correct without interacting with the left one first.
