Brain Test 5 Level 121

Overview

Level 121 contains two short rounds. The first shows a garden umbrella standing on grass with two overlapping prompts, "Protect her ice cream!" and "Feed the fish enough," a 5/5 progress mark, and a green check, indicating a feeding or shelter task that has a counted completion condition. The second round shows a digit sequence across the top, 5 4 3 6 2 5 4, beside a set of loose shapes: a red square, a yellow pentagon, a purple triangle, a light-blue hexagon, and a diagonal line segment. The first round is a simple protection or feeding action, and the second matches each number to a shape with that many sides.

• Difficulty: Regular
• Estimated moves: 7

Step-by-Step Solution

1. In the first round, read the overlapping prompts. The umbrella on the grass supplies shade, which protects the ice cream from melting in the sun, while the 5/5 mark tracks how much the fish have been fed.
2. Position the umbrella over the ice cream so it stays shaded, and provide the available food to the fish until the progress count reaches the full 5/5.
3. Watch for the green check that confirms both the ice cream is protected and the fish are fully fed. The first round then clears to the shape round.
4. In the shape round, read the sequence 5 4 3 6 2 5 4 across the top. Determine what number each loose shape represents by counting its sides.
5. Match the square to four sides, the pentagon to five sides, the triangle to three sides, and the hexagon to six sides. The line segment represents the two-endpoint value in the sequence.
6. Follow the sequence left to right: for each digit, select the shape whose side count matches that number. Place or tap the shapes in the order the digits require.
7. After the first 5 comes the four-sided square, then the three-sided triangle, the six-sided hexagon, the two-endpoint line, and then repeat the pentagon and square for the final 5 and 4.
8. If a shape is rejected, recount its sides rather than guessing; the rejected mark at the top shows the first pick was wrong. When the sequence is matched correctly, the round clears and the level reaches its completion celebration.

Strategy & Reasoning

The second round turns numbers into geometry. Every digit in the sequence stands for a polygon trait, so the puzzle is solved by counting sides once for each shape and then matching them in order. The colors and positions of the shapes are distractions; the real key is how many sides each figure has.

The 5 4 3 6 2 5 4 pattern deliberately repeats the 5 and 4 at the end, so the pentagon and square are used twice. A common mistake is picking shapes once and then having no matching figure left for the repeated digits, which is why the side-count mapping has to be established before selecting anything.

The first round keeps the two prompts together on one screen, but the umbrella and the 5/5 count split the jobs clearly: shade for the ice cream, feedings for the fish. Completing the count before moving on avoids leaving either task half done.

Tips & Common Mistakes

• Do not choose shapes by color or where they sit on the page; match the digit to the shape's side count.
• Do not forget the pentagon and square are reused for the repeated 5 and 4 near the end of the sequence.
• Do not leave the fish underfed in the first round; reach the full 5/5 count before accepting the round.
