Brain Find Level 79

Overview

Level 79, subtitled "Elementary school students can do it," shows three test tubes standing side by side against a blank white background. The left and right tubes are empty, while the middle tube contains three stacked liquid layers — from bottom to top, red, blue, and yellow. At the bottom of the screen a circular goal icon shows a test tube filled with green liquid. The level is a color-mixing puzzle rather than a complex sorting puzzle: the hint "elementary school students" points to basic paint-mixing knowledge, where yellow plus blue makes green. The overall approach is to separate the layers, combine the yellow and blue into green, and leave the red aside.

• Difficulty: Easy
• Estimated moves: 3

Step-by-Step Solution

1. Read the middle tube carefully. From bottom to top it holds red, then blue, then yellow. The two outer tubes are empty, and the goal icon wants green liquid.

1. Remember elementary color mixing: yellow and blue together make green. Red cannot contribute to green, so the red layer has to be set aside in one of the empty tubes while you work with yellow and blue.

1. Pour the top yellow layer off the middle tube into one of the empty side tubes. Tap the middle tube, then tap an empty side tube, so only the yellow layer tips across. The middle tube now shows red at the bottom with blue sitting on top of it.

1. Pour the blue layer from the middle tube onto the yellow you just set aside. Blue and yellow meet in the same tube and mix together, turning into green liquid. The middle tube is left holding only the red layer.

1. The tube that now contains the green mixture matches the goal icon. The level completes with a "Good" banner and the message "You are good at colour matching!", displaying a tube with green liquid at the bottom and a yellow layer on top.

Strategy & Reasoning

The level's whole joke is that it looks like a tricky water-sorting puzzle, but it only asks for knowledge every child has: yellow and blue make green. A player who treats it as a complex tube-sorting challenge will waste time trying to keep colors perfectly separated, when in fact the game WANTS two colors to collide and merge.

The red layer is the distraction. Because it sits at the very bottom of the stack, it blocks the yellow and blue from touching, and it has no role in making green. The correct sequence therefore removes red from the equation rather than trying to sort it neatly. Once yellow and blue are allowed to share a tube, they combine automatically into green, which is exactly what the goal icon requests.

Trying to pour the whole middle tube at once, or trying to make green by adding red, fails: red plus yellow makes orange and red plus blue makes purple, neither of which is the requested green. The only pair that produces green is yellow plus blue, so the solution is forced to isolate those two colors and discard the red. This is why the level labels itself as easy — it rewards basic color knowledge more than tube-managing skill.

Tips & Common Mistakes

• Common mistake: trying to keep every color perfectly separated like a normal water-sort game. Here you WANT yellow and blue to merge into green, so pour them into the same tube on purpose.
• Common mistake: trying to include the red layer in the mixture. Red plus yellow or red plus blue never makes green; red must be left alone in a tube.
• Common mistake: reaching for green by combining red with anything. Only yellow plus blue produces green — set the yellow layer aside first, then pour the blue onto it.
