Birdsuite Solve
Press a cell, drag to a number, release – play with mouse, touch or even a hand gesture in front of your camera.
A quick sudoku in between, a few printed puzzles for the train ride, the family or the classroom: that shouldn't require an ad-ridden app or an account – a browser tab is enough.
Solve generates every puzzle fresh with a guaranteed unique solution, in four difficulty levels from easy to expert. You play through a number wheel: press a cell, drag to a number, release – with mouse, touch, or entirely touch-free via hand gesture in front of your camera.
Everything happens locally in your browser: generating, playing, checking, and the PDF booklet with its solutions section. With hand control, the camera image is analysed locally only – nothing is recorded or uploaded.
