## What is Chordline?

Chordline is a line puzzle: connect the dots of matching colors and fill every square on the board. Each connection raises the pitch by a half step, and the moment the board is full, every line lights up at once.

HOW TO PLAY
• Drag from a colored dot to its matching pair
• Retrace a line to erase it — no undo button needed
• Connect every pair while filling the entire grid

WHAT YOU GET
• 984 puzzles across three ladders: Easy, Hard and Extreme
• Every board has exactly one solution, and every one of them was verified
• No fail state and no rush: a round runs 10 to 30 seconds
• Shapes alongside colors, so pairs stay distinguishable with color blindness
• Remove ads with a single purchase, no subscriptions

A puzzle that turns solving into playing an instrument.
