Brain Test 5 Level 120 - Walkthrough & Answer

Brain Test 5 Level 120 is a four-part "Paint the ball" colour-mixing level. Part 1 mixes blue+red+green in the gray half-bowl to paint the ball gray with a blue middle stripe. Part 2 paints the top of the ball blue and the bottom red using the brush held one colour at a time. Part 3 mixes the three cans into black to paint the ball black with a brown middle stripe. Part 4 mixes two different colours in the bowl in sequence to paint the top gray, the bottom purple, and leave a clean blue stripe across the middle.

Quick tactics for this level

Tip 01

Paint the stripe colour first and mix the surround colour in the gray half-bowl second. The brush is the only painter and holds one colour at a time, so the dip order is what keeps the stripe clean and the surround reading as the right shade.

Tip 02

On Part 2, paint blue on the top first and red on the bottom second. Reversing the order turns the top half purple and the page fails.

Tip 03

On Part 4, re-mix in the gray half-bowl between the gray top stroke and the purple bottom stroke. The brush still carries the previous mix, so the purple will not come out clean without a second bowl pass.

Step-by-step solution

On "Paint the ball gray with a blue stripe.", dip the purple brush in the blue can and drag it across the middle of the white ball to lay down a blue horizontal stripe. Mix blue, red, and green together in the gray half-bowl to make dark gray, dip the brush in the dark gray mix, and paint the rest of the ball so only the blue stripe shows through.

On "Paint the ball blue top and red bottom.", dip the brush in the blue can first and paint only the top half of the ball. Then dip the same brush in the red can and paint only the bottom half so the two colours stay on their own halves.

On "Paint the ball black with a brown stripe.", dip the brush in the blue can and drag it across the middle of the ball to lay down a blue stripe. Mix blue, red, and green in the gray bowl to make black, dip the brush in the black mix, and paint the rest of the ball so the blue stripe sits as a brown band across the dark surround.

On "Paint it gray top, bottom purple, and a blue middle stripe.", dip the brush in the blue can and drag it across the middle of the ball to lay down a blue middle stripe. Then mix blue, red, and green in the gray bowl to make gray and paint the top half of the ball.

Re-mix red and blue in the gray bowl to make purple, dip the brush in the purple mix, and paint the bottom half of the ball so the blue stripe stays clean between the gray top and the purple bottom.

Wait for the fourth green check mark. The level only clears when every page has its own green check and the level success card with the line YOU HAVE BECOME A BALL PAINTING ARTIST appears at the end.

Common mistakes

Mistake 01

Painting the bottom of the ball red before the top blue on Part 2. The brush is still loaded with red when the second stroke starts, so the top half turns purple and the page fails with a red X.

Mistake 02

Skipping the gray half-bowl mix on Part 1 and Part 3, or going straight from a single can to the ball. A single can colour never reads as gray or black, and the page stays unfinished until all three colours are mixed in the bowl.

Board notes

Layout

Every page opens on the same notebook layout: the prompt text at the top, a round paint brush with a wooden handle on the left and a round purple paint brush on the right above the ball, a half-ball in the middle (a white circle on the left to paint, paired with a small gray half-bowl on the right for mixing), and three open paint cans in a row at the bottom (blue on the left, red in the middle, green on the right) with a RESET button underneath.

Goal

Complete four sequential paint-mixing pages with one paint brush, one mixing half-bowl, and three paint cans. Part 1 needs a dark gray ball with a blue middle stripe. Part 2 needs the top half painted blue and the bottom half painted red. Part 3 needs a black ball with a brown middle stripe. Part 4 needs a gray top half, a purple bottom half, and a blue middle stripe. The run only clears when the green check mark appears on every page and the level success card with the line YOU HAVE BECOME A BALL PAINTING ARTIST shows at the end.

Opening

On Part 1, dip the purple brush in the blue can and drag it across the middle of the ball to lay down a blue stripe, then mix blue+red+green in the gray half-bowl to make dark gray and paint the rest of the ball. On Part 2, dip the brush in the blue can and paint only the top half of the ball, then dip the brush in the red can and paint only the bottom half. On Part 3, dip the brush in the blue can and drag it across the middle of the ball to lay down a blue stripe, then mix blue+red+green in the gray bowl to make black and paint the rest of the ball. On Part 4, dip the brush in the blue can and drag it across the middle of the ball to lay down a blue middle stripe, then mix blue+red+green in the bowl to make gray and paint the top, and re-mix red+blue in the bowl to make purple and paint the bottom.

Danger Zone

The brush holds one colour at a time, so the dip-then-paint order is the chokepoint on every page. On Part 2, painting the bottom red first leaves the brush loaded with red and the second stroke turns the top half purple instead of blue, which fails the page with a red X. On Part 1 and Part 3, the danger is skipping the bowl mix and going straight from the can to the ball, because a single can colour never reads as gray or black. On Part 4, the second and third colour steps both use the same brush, so the player has to re-mix in the gray half-bowl between the gray top stroke and the purple bottom stroke or leftover gray turns the bottom into a muddy brown. The RESET button is the only way back from a bad mix.

Mechanics

Level 120 is a four-act paint-mixing set that escalates from a one-mix paint job with one stripe colour (Part 1, blue stripe plus gray mix), to a two-colour split with no mixing (Part 2, blue top and red bottom in a strict dip order), to a one-mix job where the stripe colour and the surround colour interact (Part 3, blue stripe plus black mix that reads as brown against the dark surround), and finally to a three-colour page that needs two separate bowl mixes in the right order (Part 4, gray top, purple bottom, blue middle). The paint brush is the single painter, the gray half-bowl is the only mixer, and the three cans are the only colour sources. The notebook page-turn between prompts is the cue that the colour plan has changed, and the green check mark on each page is the only signal that the paint job for that page has been accepted.

Level 120 FAQ

How do I get the brush to hold a different colour on each page in Brain Test 5 Level 120?

Drag the paint brush into one of the three open paint cans (blue, red, or green) to load it with that single colour, or drag it into the gray half-bowl after the bowl already contains a mix of two or three cans to load it with the mixed colour. The brush holds one colour at a time, so a fresh dip in a can or in the bowl is required before every new stroke, and the gray half-bowl is the only place colours can be combined.

Why does Part 4 of Brain Test 5 Level 120 need a second bowl mix for the purple bottom?

The brush is still loaded with the gray mix after the top stroke, so dipping it in the red and blue cans after that will only mix the new colours on top of the leftover gray and the bottom turns muddy. The cleanest path is to first mix red and blue in the gray half-bowl to make purple, then dip the brush in that bowl and paint the bottom half so the purple comes out as a single shade next to the blue middle stripe and the gray top.
