Brain Out Level 63

Overview

The prompt "Find green" shows six colored squares: red, bright magenta, magenta, yellow, black, and blue. None of them is green. The puzzle is a color-mixing trick: green does not appear on screen, but you can create it by combining yellow and blue, which are present.

• Difficulty: Easy
• Estimated moves: 2

Step-by-Step Solution

1. Look at the six squares. The bottom row, from left to right, is yellow, black, and blue. None of them is green.
2. Press and hold the yellow square. Drag it onto the blue square.
3. As the yellow square overlaps the blue square, the colors mix into green. A green square appears where the two overlap.
4. Tap the newly formed green square. The congratulations popup appears with the message "WOW! Surprise!"

The six squares are red, magenta, magenta, yellow, black, and blue. None of them is green. The puzzle is a color-mixing task.

Press and hold the yellow square. Drag it onto the blue square. As they overlap, the colors mix into green. Tap the newly formed green square, and the level clears with the message WOW! Surprise!

Drag the yellow square onto the blue square. They overlap and turn green. Tap the resulting green square. If you drag yellow onto black, you get a dark smudge, not green. Only yellow plus blue produces green in this game.

If the yellow and blue squares do not change color when you release them, make sure they overlap fully rather than merely touching at an edge. The color mixing only happens when the two squares are stacked on top of each other in the same screen position.

Strategy & Reasoning

This is a subtractive color-mixing puzzle. Yellow paint mixed with blue paint produces green, and the game implements this by letting you drag the yellow square onto the blue square. The red, magenta, and black squares are decoys. The black square is the biggest trap — it looks like it could be mixed with something, but black does not produce green with any other color on screen. Only yellow plus blue works.

Color mixing is the key mechanic. Yellow paint plus blue paint produces green, which is basic subtractive color theory. The black square is the biggest decoy because it looks like it could darken any color, but black mixed with anything stays dark. The magenta squares are also decoys. Once you drag yellow onto blue, the overlapping region turns green, and tapping that region clears the level.

The red, magenta, and black squares are all decoys. Red mixed with anything does not produce green, magenta mixed with anything produces purple, and black darkens rather than lightens. Only yellow and blue, the two primary colors for subtractive mixing, produce the green square the game is looking for.

Tips & Common Mistakes

• Do not tap any of the existing squares. None of them is green.
• Do not mix yellow with black or red. Only yellow plus blue makes green.
• Do not drag blue onto magenta. That produces purple, not green.
