01 / Instructions
How to use this test
On a touchscreen, drag through each cell and use multiple fingers. Keep browser navigation gestures away from the edges.
02 / Next step
Understand your result
A completed grid means those cells received pointer events. Retest blank regions after rotating the device or removing an interfering accessory.
03 / Testing methodology
What this test cannot tell you
A mouse can fill the grid but does not test touch. Multi-touch limits vary with hardware and browser; a grid alone cannot certify the whole digitizer.
