Brain Test 5 Level 128

Overview

Level 128 is another shape-counting sorting puzzle under the prompt "Remove the extra shapes." The first composite outline at the top is a nested square frame with a circle in the center and two small triangular corners, while below it lie loose blue squares and circles. The second composite is a rectangular frame holding two circles, triangles pointing out from the sides, and two small square blocks at the edge, with a row of loose triangles, squares, and circles underneath. The task is to keep only the shapes the composite figures actually require and remove every spare piece.

• Difficulty: Regular
• Estimated moves: 6

Step-by-Step Solution

1. Read "Remove the extra shapes." Focus on the composite outline above and name the shape types used inside it before touching any loose piece.
2. Count the shapes in the first composite: the outer and inner square frames, the central circle, and the two corner triangles. Trace each closed outline so a partly hidden piece is not missed or double counted.
3. Compare that inventory with the loose blue shapes below. For each type, keep the number matching the composite and mark the rest as extras to remove.
4. In the first composite, match the loose squares to the frame corners, the circles to the center, and the triangles to the corner pieces. Drag away any square or circle that has no place in the figure.
5. Move to the second composite and recount its contents: the two circles, the side-pointing triangles, and the two small edge squares.
6. Compare the second loose row against this count. Keep the required triangles, squares, and circles, and discard the remaining extras of each type.
7. After removal, check that the kept loose shapes match the composite exactly, with no spare triangle, square, or circle left over.
8. When the kept shapes line up with the figure's composition, the round clears and the level reaches its completion celebration.

Strategy & Reasoning

This puzzle starts from the composite figure as the target, so reading its shape inventory first decides which loose pieces are needed. Color and size are not the sorting rule; the side count and shape category are what matter. Working backwards from the outline keeps you from keeping a loose shape just because it looks similar to another one.

Overlapping outlines are the main counting trap. A square frame and an inner circle can sit on top of each other, and a triangle may share an edge with a square, so each closed figure should be traced separately before the count is settled. Once the counts are known, splitting loose shapes into needed and spare is straightforward.

The rejected mark in the second composite shows that an early removal picked the wrong shape. If the kept set does not match the outline, go back and recount rather than deleting more pieces blindly. The goal is an exact match, not clearing the loose row entirely.

Tips & Common Mistakes

• Do not sort loose shapes by color or position; match each one to the shape type the composite needs.
• Do not overlook shapes partly hidden inside another outline; trace every closed figure before counting.
• Do not remove more pieces than the composite requires; keep the exact number of each shape it uses.
