Hopsa
A small grid with pictures introduces logical thinking – "it can't go here, so it must go there" – long before kids can do number sudoku. It's quiet, it fits on a scrap of paper and it's very satisfying to finish.
The steps are in the app
Step-by-step instructions, tips and an easier and a harder version are waiting in the Hopsa app – along with 300 more ideas matched to your kids’ ages.
Coming soon to the App Store and Google Play
