OddOneTots
Which one doesn't belong? Four pictures, and every answer is right if it has a reason: the straw, because it isn't metal; the spoon, because it's round. Whybird asks why, then asks if a different one could be the odd one out. Use the picture decks, or snap four things at home that stay on your device. Ages 3–5.
Built for sittings of about 10 minutes on the screen. That is our design budget, not a measurement.
