Brain Blow Level 23

Overview

Four hands float on the board in different poses: a fist at the top, an open palm on the right, a fist on the left, and another fist at the bottom. The prompt asks you to find the odd hand out. Tapping each fist cycles it through a different gesture, which reveals the hidden poses and leaves one hand that never changes. After all four have been checked, the open palm on the right stands out as the odd one, since the other three started as fists and cycle through closed gestures.

• Estimated moves: 5

Step-by-Step Solution

1. Identify the four hands and their starting poses: the top hand is a fist, the right hand is an open palm, the left hand is a fist seen from behind, and the bottom hand is a fist.

1. Tap the top fist once to cycle it to its next gesture, noting how the hand changes shape. Each tap on a fist rotates through the available closed-hand poses.

1. Tap the left fist and the bottom fist in turn so every fist is cycled once and its hidden gesture is revealed. The open palm on the right does not transform when tapped.

1. Compare the resulting four poses: the three former fists now show different closed gestures, while the right hand remains an open palm throughout. The open palm is the odd hand because it never belongs to the fist group.

1. Tap the open palm on the right to finish the level. The cycled fists stay in their new poses, and the level completes once the unchanging hand is selected.

1. After tapping each fist once, note its new pose beside the original open palm, and compare whether any cycled hand still keeps an open spread of fingers. The three former fists all settle into closed or pointed gestures, while the right hand remains open the whole time, which is the stable mark of the odd one. If you are unsure which hand changed, retrace the tap order: any hand that began as a fist belongs to that group even after its pose cycles.

Strategy & Reasoning

Odd-hand puzzles hide the category behind the starting poses. Three hands begin as fists and share that origin, while the open palm starts differently, so tapping the fists reveals their alternatives and confirms they belong to one group. The open palm is the only hand with no fist counterpart.

Because the gestures change after each tap, the first-screen comparison can mislead; a fist that looks plain at the start turns into a pointing hand or a thumbs-up once cycled. Checking every hand once before choosing prevents mistaking a transformed fist for the odd one. The open palm stays open through the whole sequence, which is the stable signal that marks it out.

Tips & Common Mistakes

• Tap all four hands once before deciding; fists change gesture, and judging only the starting pose can misidentify the odd one.
• Look for the hand that never closes into a fist or cycles a closed gesture; the open palm keeps its fingers spread throughout.
• Do not tap a cycled fist after its transformation; it still belongs to the fist group even though its new pose looks different.
