How to play

Trace a path to the target.

Choose a difficulty and start the 90-second round.
Drag through numbers that touch horizontally, vertically, or diagonally.
Release when the running total equals the target.
A correct path scores one point and refreshes only the numbers you used.

Each cell can appear only once in a path. Going over the target does not end the path, so you can keep exploring before you release.

What it practices: visual scanning, mental arithmetic, short-term memory, path planning, and sustained attention.
