Brain Test 5 Level 118

Overview

Level 118 is a shape-counting and sorting puzzle under the prompt "Remove the extra shapes." A composite outline figure sits at the top of the page, built from triangles, squares, and circles, while loose blue shapes of those same types lie below in rows. The second round shows another composite rectangle made from two circles, several triangles, and small square blocks, with a fresh set of loose triangles, squares, and circles underneath. The task is to keep only the shapes the composite figure actually needs and remove every spare one.

• Difficulty: Regular
• Estimated moves: 6

Step-by-Step Solution

1. Read "Remove the extra shapes." Look at the composite figure at the top and identify which shape types appear inside it: triangles, squares, and circles.
2. Count how many of each shape the figure uses. Trace the outline carefully so a shape partly hidden behind another is not missed or counted twice.
3. Compare that count with the loose shapes below. For each type, keep the number matching the figure and mark the rest as extras.
4. In the first composite, the inner figure contains a circle, square-like corner blocks, and triangular corners. Match the loose triangle, square, and circle pieces to those positions.
5. Remove the extra shapes that do not have a place in the composite. Drag or tap the spare pieces out of the working set until the remaining loose shapes match the figure's count exactly.
6. In the second round, study the rectangle composite: it holds two circles, a set of triangles on the sides, and small square blocks at the edges.
7. Count the triangles, squares, and circles in that second composite, then compare with the loose row below. Keep the two circles, the required triangles, and the required squares; discard the remaining extras.
8. When the kept shapes match the composite figure's composition with no spare pieces left over, the round clears and the level reaches its completion celebration.

Strategy & Reasoning

The puzzle is a count-and-match exercise rather than a free-form drawing task. The composite figure defines the target, so the correct move is to read its shape inventory first and only then judge which loose pieces are extra. Guessing by color or size leaves the wrong pieces behind.

Overlapping outlines make counting the trap. A triangle may share an edge with a square, and a circle may sit inside a larger frame, so tracing each closed shape one at a time prevents undercounting. Once the figure's counts are settled, the loose shapes split cleanly into needed and spare.

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

Tips & Common Mistakes

• Do not remove shapes by type alone; the figure may need some triangles, squares, and circles while others are extras.
• Do not miss partly hidden shapes in the composite; trace overlapping outlines before counting.
• Do not keep more pieces than the figure uses; every spare triangle, square, or circle must be removed.
