Brain Out Level 70
📝 Walkthrough
Overview
The prompt "What number will the hour hand point to after 3 hours?" shows an analog clock with the hour hand pointing at 9 and the minute hand pointing at 12 — so the time is 9 o'clock. A counter shows 0 with Clear and OK buttons. The naive calculation is 9 + 3 = 12, but the trick is that the clock is a static drawing, not a running timepiece, and the hour hand does not actually move.
- Difficulty: Easy
- Estimated moves: 2
Step-by-Step Solution
- Read the clock: the hour hand points left at 9, and the minute hand points up at 12. The current time is 9:00.
- Most players calculate 9 + 3 = 12 and enter
12. This is wrong. - Recognize that the clock is a static image. The hour hand is drawn pointing at 9 and does not physically move no matter how many "hours" pass in the puzzle.
- Use the plus button to set the counter to
9, then tap OK. - The green check appears next to the number 9, and the level clears.
The clock shows 9:00, with the hour hand pointing left at 9. The prompt asks what number the hour hand will point to after 3 hours. A real clock would move to 12.
But this clock is a static drawing. The hour hand does not actually move. Use the plus button to set the counter to 9 and tap OK. The green check appears next to 9.
Set the counter to 9 using the plus button. The clock is a static drawing; the hour hand does not move. If you enter 12, the level fails. The answer is 9.
Strategy & Reasoning
The puzzle is a trick about static images. A real clock would advance from 9 to 12 in three hours, but this clock is a drawing on screen. The hour hand is fixed at 9 and cannot change. The question "what number will the hour hand point to" refers to the hand as drawn on the screen, not to a live simulation. Answering 12 assumes time is passing, which it is not. The correct answer is the number the hand already points to: 9.
The clock is a static image, not a running timer. The hour hand is drawn pointing at 9 and never moves, no matter how many hours you imagine passing. If you calculate 9 plus 3 equals 12, you are treating the clock as a real timepiece, which it is not. The answer is the number the hand already points to, which is 9. This is a common Brain Out trick about static drawings.
Tips & Common Mistakes
- Do not calculate 9 + 3 = 12. The clock is not running.
- Do not try to drag the hour hand. It is fixed.
- Do not overthink the clock face. The hand points at 9, so the answer is 9.
