What This Game Is
Pearl is a self-contained logic puzzle built around one clear objective. Each new board gives you a fresh problem to solve, so it works well for quick sessions and repeated play.
Draw a single closed loop, given clues about corner and straight squares.
How to Play
Click with the left button on a grid edge to draw a segment of the loop through that edge, or to remove a segment once it is drawn. Drag with the left button through a series of squares to draw more than one segment of the loop in one go. Alternatively, drag over an existing part of the loop to undraw it, or to undraw part of it and then go in a different direction.
Most puzzles in this collection reward deduction more than speed. Focus on the most limited choices first, use the clues to narrow the board, and avoid guesses unless the puzzle mode clearly expects them.
Beginner Tips
- Start with the area that has the strongest clue or the fewest legal options.
- Use marks, notes, or temporary indicators if the puzzle supports them.
- Try to preserve flexibility instead of committing too early when multiple moves look possible.
- If the board gets messy, restart a fresh puzzle and apply what you learned from the first run.
