Tap or swipe (depending on your device/control scheme) to make the snake move in a direction.
The snake moves step by step: each move you make matters.
You need to plan your path carefully so you don’t block yourself.
Your goal is to guide a snake around the puzzle board, eating apples to grow longer, and eventually reaching the portal to complete the level.
Every apple you eat adds a new segment to your snake.
As you grow, the puzzle becomes more challenging because your snake becomes longer (and harder to manoeuvre).
