Brain Puzzle 3 Level 140

Overview

Level 140 is a timed cleaning puzzle set in a disgustingly dirty public restroom. The yellow banner says "Clean the toilet thoroughly so they can use it successfully" with a 3:00 countdown. Three desperate men are clutching their bellies, shivering with urgency, surrounded by green stink lines. The room is a wreck: a toilet on the left is overflowing with blue water splash, the stall door is covered in red graffiti, there is cobweb in the corner, a man in a suit is smoking in a stall, a lump of poop sits on the floor near a urinal, and trash, a cigarette pack, a water bottle, a red fire extinguisher, a broom and a plunger litter the tiles. The subtitle pleads "I can't hold it in any longer!" The goal is to clean and ventilate the room step by step until the men can finally use the toilet.

• Difficulty: Regular
• Estimated moves: 6

Step-by-Step Solution

1. Open the window to ventilate. Tap the closed window above the blue-tiled wall. It swings open to reveal a house and greenery outside, letting the foul air start to clear. This is the first cleaning step.

1. Plunge the overflowing toilet. Tap the red plunger on the floor near the left toilet, then apply it to the overflowing bowl. The blue water splash calms down and the toilet stops flooding.

1. Stop the smoking man and clear the floor mess. The man in the suit was smoking in the stall; tap him so he stands up angrily, arms crossed, cigarette gone. Sweep the floor with the broom to clear the poop lump and the scattered trash, and drop the rubbish into the blue trash bin, which fills up with waste paper.

1. Wipe the graffiti and cobweb. Clean the red graffiti off the stall door and remove the cobweb in the corner with a cloth/rag until the walls are plain.

1. Purify the air with the potted plant. Tap the potted plant on the windowsill and hand it to the waiting man; he holds it up, and pink fragrant aroma lines spread through the room. The subtitle reads "Purify the air a bit," confirming the air is now fresh.

1. Let the men use the toilet. Once the room is clean, ventilated and deodorized, the yellow-shirt man sits down on the toilet with a relieved expression, and the beige-shirt man kneels at the stall door waiting his turn. The red "Completed" banner drops with confetti.

Strategy & Reasoning

The level is a multi-step cleaning chain. Nothing works until the room is aired out and the toilet is fixed; the green stink lines are the visual signal that the air is still foul. The order matters: open the window first, then stop the flooding toilet, then remove the floor mess and the smoker, then wipe the walls, and finally deodorize with the plant. Each tap removes one layer of grime, and the green stink lines gradually fade.

The three desperate men cannot act until the room is usable — they just clutch their bellies. The suit-and-smoking man is part of the problem (he is the source of stale smoke), so he must be dealt with before the air purifies. The potted plant on the windowsill is the deodorizer, which is why holding it up produces the pink aroma lines and the subtitle "Purify the air a bit."

There is no shortcut: tapping the waiting men or the toilets directly does nothing until the cleaning props are used. The fire extinguisher, water bottle and urinals are set dressing. The level completes automatically once the yellow-shirt man can sit on the cleaned toilet.

Tips & Common Mistakes

• Mistake: tapping the desperate men directly. They cannot use the filthy toilet; clean the room first. The men only sit down after the toilet is plunged and the air is fresh.
• Mistake: leaving the window closed. Ventilation is the first step. If the green stink lines remain, check whether the window is actually open.
• Mistake: forgetting the potted plant. The plant on the windowsill is the air purifier; holding it up produces the pink aroma lines. Without it the room still smells and the level will not finish.
