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.Look for the light-bulb icon located in the hint section at the top of the screen, not on the main dark area;
- 2.Drag the light-bulb slowly across the entire screen to gradually illuminate different sections and find the hidden cat;
- 3.If the screen remains dark, ensure you're dragging the bulb slowly and covering all areas, as the cat might be in a corner.
Common mistakes
- 1.Tapping randomly on the dark screen hoping to reveal the cat without using any light source;
- 2.Trying to use the hint button for illumination instead of noticing the light-bulb icon in the hint area;
- 3.Dragging the light-bulb too quickly, which fails to properly light up the screen and reveal the cat.
