Brain Out Level 198

Overview

Level 198 says "Fill the glass." The board shows a shelf holding an empty glass on the left, a white plate in the middle, an open matchbox, and a small candle on the right. The obvious reading is that you need to pour something liquid into the glass, but there is no pitcher, no water, and no drink anywhere on the shelf. The Brain Out twist is that "fill" does not mean fill with liquid. You light the candle, set it on the plate, and then place the empty glass upside down over the candle. The smoke from the extinguished candle fills the glass.

• Difficulty: Regular
• Estimated moves: 4

Step-by-Step Solution

1. Look at the shelf. The glass is empty, the plate is bare, the matchbox is closed, and the candle is unlit. There is no liquid container.
2. Drag the open matchbox lid aside to expose a match inside.
3. Pull one match out of the box and rub it against the side of the box to light it.
4. Use the lit match to light the wick of the small candle on the right end of the shelf.
5. Drag the lit candle onto the white plate in the middle of the shelf.
6. Pick up the empty glass and place it upside down over the candle on the plate. The flame goes out from lack of oxygen, and smoke fills the inside of the glass. The level is complete.
7. Light the candle, set it on the plate, and put the glass upside down over it. The candle consumes the oxygen inside the glass and the water rises.

Continue the action described in the previous steps until the level-complete pop-up appears.
After lighting the candle, set it on the plate next to the glass. Then pick up the glass and turn it upside down over the candle. The flame consumes the oxygen inside the glass, and the water rises on its own.
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 plays on the word "fill." In everyday language, filling a glass means pouring a drink into it, but the scene provides nothing drinkable. Brain Out reframes "fill" as "fill with whatever is available." The only thing on the shelf that can fill a vessel is the smoke from a candle. The plate, the matchbox, and the candle are all laid out for the classic candle-under-glass experiment, just without the water. 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

• Looking for water or a drink to pour. There is none; the glass is filled with smoke.
• Covering the candle before lighting it. The candle must be burning when you place the glass over it.
• Leaving the candle on the shelf instead of on the plate. The plate is the surface under the glass; move the candle onto it first.
