Honey comb challenge.

The Honeycomb Challenge is one of the deadly games featured in the South Korean TV series "Squid Game." In this challenge, contestants are given a large, fragile honeycomb-shaped sugar cookie with a different symbol imprinted on each of its 16 segments. Their task is to use a needle to carefully carve out the shape without breaking any part of the honeycomb. They must do this within a limited time, or they will be eliminated from the game. The challenge is both mentally and physically demanding, as it requires precision and a steady hand.

The Honeycomb Challenge in "Squid Game" is known for its intense suspense and the dire consequences of failure, as players who fail this challenge face a deadly consequence. It's just one of several deadly games that the characters are forced to participate in throughout the series.
