Brain Out Level 174
📝 Walkthrough
Overview
Level 174 asks: "Monkey can pick 2 pineapples per 1 minute, how many can he pick with 10 minutes on the tree?" The board shows a single leafy green tree with a brown trunk, a monkey hanging from one of its thin branches, and a yellow Enter field plus a blue OK button below. The arithmetic looks straightforward at first: 2 pineapples per minute times 10 minutes equals 20. But the Brain Out twist is biological. Pineapples do not grow on trees at all; they grow close to the ground on low leafy plants. There is no pineapple on this tree, so the monkey can pick zero. The correct answer to type is 0.

Step-by-Step Solution
- Read the question carefully. It gives a rate of 2 pineapples per minute and a time of 10 minutes, which is designed to make you multiply 2 by 10 and write 20.
- Look at the tree in the drawing. It is a generic leafy tree with a round green canopy and a brown trunk. There is no pineapple visible anywhere on it, and no fruit of any kind.
- Ask yourself whether pineapples actually grow on trees. In real life, pineapples grow on short plants near the ground, not up in tree canopies. A monkey sitting in a tree cannot pick pineapples from it because the tree has none.
- Tap the yellow Enter field. The on-screen keyboard appears. Type the digit 0.
- Tap the blue OK button. A green check mark appears across the tree and the level-complete state is reached. The puzzle accepts 0 because there are no pineapples to pick.
- Drag the monkey around the screen. No pineapples are growing on the tree, because pineapples grow on the ground. The answer is zero.
Dragging the monkey to any part of the tree changes nothing, because there are no fruit sprites to collect. The zero answer is entered by tapping the monkey and then typing nought on the keypad that appears.
If the monkey keeps climbing back onto the tree, drag him off the trunk and wait. No pineapple sprite appears anywhere on the screen, which is the proof that the answer is zero. Type zero into the input field and confirm.
Strategy & Reasoning
The puzzle is a trick question disguised as arithmetic. The numbers 2, 1, and 10 are all there to bait you into a multiplication. Brain Out regularly gives you a fully specified math problem and then asks you to notice one real-world fact that breaks the math. Here, the fact is that pineapples are not tree fruit.
Tips & Common Mistakes
- Multiplying 2 by 10 and entering 20. The arithmetic is a trap; pineapples do not grow on this tree.
- Looking for a hidden pineapple behind the leaves. There is no pineapple to find; the answer is simply 0.
- Assuming the monkey can pick from somewhere off-screen. The question specifies "on the tree," and the tree contains no pineapples.
