Our play note

Why Coastal Lines is worth your time

Its visual rules are easy to read and every mistake can be reversed, which keeps harder boards pleasant.

How to play

Draw a line between matching islands without crossing another route.

  1. Start with the most open part of the board.
  2. Make one move at a time and watch what it reveals.
  3. Use restart when a board stops feeling productive.

Tips from our test round

Keep one flexible option available instead of taking every obvious match. The game is most satisfying when you pause briefly before clearing a pair.
