Your goal is to connect all dots with a single continuous line — following the real connections between them — without lifting your finger or retracing any line.
Let's learn how to play!
Connecting Dots
Drag from one dot to the next along a visible connection line. You can chain several connections in one continuous drag.
Try it yourself in this practice area.
Rules to Remember
• You can only move along a real connection line
• You can't visit the same dot twice, or retrace a line
• Breaking a rule resets the level automatically
Watch what an invalid move looks like.
Tools & Features

How to play
Drag from dot to dot, following the faint lines — you can only move along a real connection.
Trace every dot exactly once. You cannot revisit a dot or retrace the same line twice.
Break the rule and the level resets automatically — figure out the right starting dot and order.
Use Undo/Retry/Skip if you get stuck. Hints show the solution (dashed); toggle in Settings.
