Brain Out Level 171
📝 Walkthrough
Overview
Level 171 asks you to "Find out the ping pong ball." The scene shows a wooden table holding a blue baby pacifier on the left, a slice of watermelon on a white plate in the center, and a half-full glass of water on the right. Below the table are an orange Corgi, a colorful beach ball, and a blonde girl in a red dress. A wooden chair behind the table holds a painted Russian matryoshka doll. A ping-pong ball is somewhere in this room, but it is not visible on any surface at first. The Brain Out twist is that it is sitting underneath the watermelon plate, hidden from view until you slide the plate away.

Step-by-Step Solution
- Scan every visible object on the table and on the floor. The pacifier, the water glass, the Corgi, the beach ball, the girl, and the doll are all clearly not a ping-pong ball. The only thing that could be hiding a small round object is the watermelon sitting on its plate.
- Press and hold on the watermelon slice (or on the plate beneath it) and drag it to the side. The plate slides across the wooden table, revealing the surface underneath.
- A small white ping-pong ball appears on the table surface where the plate used to sit. It is plain white and round, easy to recognize once the plate is out of the way.
- Tap the ping-pong ball. The level-complete pop-up appears with the line "Unexpected!" Tap Next to continue.
- If sliding the watermelon does not reveal the ball, try dragging the plate itself rather than the fruit; the whole dish slides as one object in this puzzle.
- Lift the plate away from the table. The ping-pong ball was hidden underneath it. Drag the ball into the empty glass or hand it to the person who asked for it to finish.
If the plate refuses to move, press harder on the edge of the dish rather than the ball underneath it. Once the ping-pong rolls out, the level recognizes the pickup immediately.
Strategy & Reasoning
The puzzle is a hidden-object problem dressed up as a room scene. Brain Out scatters a lot of visually distinctive items to make you inspect each one, but the actual trick is that a small white ball blends into a white plate. The watermelon on top of the plate blocks your view of the plate surface, and the plate itself blocks the table surface below it. Removing the only object large enough to conceal a small ball is the natural deduction.
Tips & Common Mistakes
- Tapping the beach ball thinking it is the target. It is too large and too colorful; the ping-pong ball is small and white.
- Trying to open the Russian doll. The doll is a decoy; the ball is not nested inside it.
- Dragging only the watermelon slice off the plate while leaving the plate covering the table. Move the whole plate to expose the surface beneath.
