Brain Out Level 201

Overview

Level 201 says "Fill the glass." The board shows an empty glass on the left, a plate with a fish on it in the middle, an open matchbox, and a small pepper shaker on the right. There is no liquid anywhere on the shelf. The Brain Out twist is the same as the candle version of this puzzle: you light a match and place it under the empty glass, then wait for the smoke to fill the glass. The match is the combustible, not the candle.

• Difficulty: Regular
• Estimated moves: 3

Step-by-Step Solution

1. Look at the shelf. The glass is empty, the plate is just a fish plate, the matchbox is open, and the pepper shaker is a decoy. There is no liquid.
2. Pull a match out of the open matchbox.
3. Rub the match head against the side of the box to light it.
4. Place the lit match on the shelf under the empty glass.
5. Put the empty glass upside down over the lit match.
6. The match burns out and smoke fills the inside of the glass. The level-complete pop-up appears with the line "Nice!" Tap Next to continue.
7. This is the same inverted-glass trick as level one ninety-eight: light the candle, set it on the plate, and invert the glass over it.

The candle is already lit in this variant; you only need to set it on the plate and invert the glass. The water rises on its own once the oxygen is consumed.
The candle is already lit in this variant; you only need to set it on the plate and invert the glass. The water rises on its own once the oxygen inside the glass is consumed.
If the pop-up does not appear on your first attempt, repeat the action described above; the level triggers completion the moment the required object is placed or the required gesture finishes.

Strategy & Reasoning

The puzzle is a variation on the candle-under-glass experiment. The word "fill" is not asking for a drink; it is asking for anything to occupy the glass. The only combustible on the shelf is the match, and lighting it produces smoke. The plate with the fish is a food-related decoy, and the pepper shaker is a condiment decoy. Neither is a liquid that fills a glass. This level follows Brain Out's signature rule: the obvious action rarely works, and the solution usually involves either moving an on-screen object that looks fixed, using a hardware button, or treating the prompt text itself as a draggable element. Once you recognize the pattern, the trick becomes easy to spot.

Tips & Common Mistakes

• Trying to use the pepper shaker as a drink. It is a decoy.
• Covering the match before lighting it. The match must be burning when the glass goes over it.
• Forgetting to take the match out of the box. The match is inside the open matchbox; pull one out first.
