Brain Out Level 56

Overview
The prompt "Which shape has the most sides?" shows four shapes: a light-blue slanted quadrilateral in the upper left, a dark-blue U-shaped block in the upper right, a pink circle in the lower left, and a red cross-like shape in the lower right. Counting straight sides gives the blue U-block around eight sides and the red cross around twelve, while the light-blue quadrilateral has four and the circle appears to have none. The trick is that a circle has infinitely many sides, not zero.
- Difficulty: Easy
- Estimated moves: 1
Step-by-Step Solution
- Count the sides of each straight-edged shape. The light-blue quadrilateral has four sides. The dark-blue U-block has roughly eight sides. The red cross shape has roughly twelve sides.
- Look at the pink circle in the lower left. It has no straight edges, but mathematically a circle can be thought of as a regular polygon with infinitely many sides.
- Tap the pink circle. The game immediately accepts it as the shape with the most sides and pops the congratulations message: "Does a circle have 0 or infinite sides? It's a question!"
The four shapes are a light-blue quadrilateral, a dark-blue U-shaped block, a pink circle, and a red cross shape. Counting straight edges gives the red cross the most visible sides, but the question is asking which shape has the most sides in the mathematical sense.
Tap the pink circle. The game immediately accepts it and pops a message asking whether a circle has zero or infinite sides. This confirms that the intended answer is the circle, because a circle can be thought of as a regular polygon with infinitely many sides.
Tap the pink circle in the lower-left area. Do not tap the red cross, even though it has many visible corners. The game's response confirms the answer is the circle. If you tap the blue U-shape or the light-blue quadrilateral, the level does not react. The circle is the only shape that represents infinity.
Strategy & Reasoning
This is a wordplay puzzle about the definition of "sides." A naive player counts the visible straight edges of the polygon shapes and picks the red cross, which has the most corners. But the question asks which shape has the most sides, and in geometry a circle is the limit of a regular polygon as the number of sides approaches infinity. That makes the circle the winner by an infinite margin. The game even comments on this in its congratulatory message, confirming the intended answer is the circle.
Tips & Common Mistakes
- Do not pick the red cross. It has many visible straight sides, but it is still finite.
- Do not pick the dark-blue U-shape. It looks complex but only has about eight sides.
- Do not argue that the circle has zero sides. The game's answer treats it as infinite, which is the accepted Brain Out logic.
