Kids World
Small boards for small hands
4×4, 6×6 and 9×9 boards with animal pictures in place of numbers, their own profile, and stars and stickers for every finished puzzle. A wrong tile simply hops back, so there is no way to fail. The same app, so nobody needs a second download.
- 4×4 · 6×6 · 9×9
- Own profile
- Stickers, no scores
iPad + Apple Pencil
Write your notes in the square
Scribble a number and it is read as an entry; write small and it becomes a pencil mark. Landscape and portrait both.
Apple Watch
A Daily Mini on your wrist
A 4×4 daily puzzle that takes about a minute, your streak at a glance, and complications for your watch face. Keep your streak alive on the days you never pick up your phone.
