Brain Blow Level 83

Overview

Three colored rectangles sit on a white screen: a green block on the left, a narrow blue block beside it, and a wide red block stretching below them. The prompt asks you to find the largest rectangle. On the visible colored shapes, the red block looks biggest, but it is not the true answer. The scene is zoomed in so tightly that a much larger rectangle frame surrounding all three shapes has been cropped away; pulling the view back reveals it.

• Difficulty: Easy
• Estimated moves: 1

Step-by-Step Solution

1. Read the prompt asking for the largest rectangle, and compare the three colored shapes on screen. The green and blue blocks sit side by side in the upper area, while the wide red block runs beneath them.

1. Do not tap the red rectangle just because it looks the widest among the colored shapes. Its size is compared against other rectangles that are currently hidden outside the close-up view.

1. Perform a pinch-out zoom on the screen, spreading two fingers apart to shrink the view and pull the camera back. As the zoom changes, the colored blocks become smaller in the frame.

1. Watch the edges of the scene come into view. A large black-outlined rectangular border appears around all three colored shapes, enclosing the whole group inside a white area.

1. This outer frame is the largest rectangle on the screen. Tap it to select it, and the green checkmark appears with the completion screen confirming the answer.

1. Keep zooming out until the full four-sided border is in view rather than tapping a partial edge; an outlined shape with straight sides and right angles counts as a rectangle even though it has no colored fill. Once the outer frame encloses every green, blue, and red piece inside it, its area clearly dwarfs any single inner block. Select that border rather than one of the filled pieces, and the checkmark confirms you chose the largest rectangle on the whole screen.

Strategy & Reasoning

The puzzle hides the biggest shape by cropping it out of view, just like the cat-painting level in this section. The colored rectangles are the small, obvious candidates, but the question asks for the largest one, and the boundary that wraps around everything is far bigger than any individual block. The zoom-out is the interaction that exposes this background frame.

Once the view widens, the black outer rectangle's dimensions are unmistakable: it spans the full width and height around the group, dwarfing the red, green, and blue pieces inside it. This is why judging size from the close-up alone leads to the wrong red block. The outer frame is a plain rectangle rather than a colored fill, so it blends into the white background until the camera pulls back and its border becomes visible.

Tips & Common Mistakes

• Zoom out to reveal the outer rectangular frame; do not pick the red block merely because it is the biggest colored shape at first glance.
• Tap the large border that encloses all three colored rectangles, not one of the inner pieces.
• If the outer frame is only partly visible, keep zooming out until its full four-sided border is in view before selecting it.
