In Snake Game, every time the player-controlled snake eats a food item, it grows in length. This seemingly small change significantly affects gameplay because the longer the snake becomes, the harder it is to navigate without crashing into its own body. What starts as a small, nimble creature quickly transforms into a sprawling, winding obstacle that the player must carefully maneuver.

This mechanic introduces a natural difficulty curve:

• At the beginning, movement is easy, with plenty of open space to navigate.

• As the snake grows, strategy becomes crucial—players must think ahead, planning their turns to avoid trapping themselves.

• The thrill comes from balancing risk and reward. Do you chase the food aggressively or take a safer route?

The growth mechanic is also what gives Snake its sense of progression. Instead of levels or power-ups, the increasing length serves as both a score tracker and a gameplay challenge. The longer you survive, the harder it gets—making every successful move feel rewarding.

This simple feature is why Snake remains one of the most iconic and endlessly replayable games ever created.
