Why do the juice cartons not work in Brain Test 5 Level 1?

The game explicitly draws all four cartons at the same size. Tapping any one gives the message "They are the same size, don't you see?!" — the cartons are a misdirection and the real biggest juice is the blue puddle on the board.

When should I tap the ground puddle in the tree section of Level 1?

Wait until the red puddle under the apple tree stops growing. Tapping it while juice is still dripping may not register. Let it reach full size first.

Brain Test 5 Level 1 Walkthrough

easy

Brain Test 5 Level 1 is solved by ignoring the four juice cartons — the game tells you they are all the same size — and tapping the large blue puddle instead, then waiting for the apple-tree juice to pool on the ground before tapping the biggest spill.

Board Notes

Layout: Level 1 opens with four colored juice puddles scattered across a white board. A small pink blob sits near the top, a medium green blob on the left, a medium yellow one on the right, and a large blue blob at the lower-left. The blue puddle is visibly the largest by a clear margin.
Goal: The board asks to tap the biggest juice. The real answer is the large blue puddle at the lower-left. The four juice cartons that appear are all the same size and tapping any one of them triggers a red X with the message "They are the same size, don't you see?!" — the cartons are a deliberate trap.
Opening: Tap the large blue puddle at the lower-left of the board first. The scene then transitions to an apple tree on a green field where red juice drips from the branches and pools on the ground. Wait for the red ground puddle to grow to its largest size, then tap it.
Danger Zone: Tapping any of the four juice cartons wastes a move and gives a wrong-answer message. In the tree scene, tapping the juice drops mid-fall or the tree trunk itself does not register. Wait for the ground puddle to fully form before tapping.
Mechanics: Level 1 establishes the core "tap the biggest X" trick — the obvious candidates are a trap, and the correct answer is a visually dominant element elsewhere on screen. The two-part structure (puddles then tree) reinforces that the answer is always the accumulated result, not the container.

Quick Tips for Brain Test 5 Level 1 (spoiler-free)

The blue blob on the lower-left is clearly bigger than any juice carton drawn on screen — trust what you can see and skip the cartons entirely.
In the tree scene, wait. The red puddle keeps growing as juice drips down. Tap it only after it stops expanding.
If you tap a carton and get the wrong-answer message, you have not lost — tap elsewhere to dismiss it and then try the blue puddle.

Common Mistakes to Avoid

Tapping any of the four juice cartons — the game confirms they are all the same size and marks it wrong.
Tapping the apple tree trunk or the dripping juice drops instead of the ground puddle in the tree scene.
