On the shelf
Pick one. They all work on a phone, a tablet or a laptop.
Why we make these
chalkolate gives toys a second life. The games are the same idea, minus the postage.
Fun first, always
If it stops being a game it stops working. The learning rides along inside the play, never on top of it.
Short by design
A round takes about five minutes. Long enough to get good at something, short enough to stop happily.
No sign-ups, no ads
Nothing to buy, nothing to log into, nothing that nags. Scores stay on your own device.
