A new, free version of the Clades Solo app is now available on Apple, Android, and Amazon. Match animals by their evolutionary histories and see how fast you can play through the deck! The new version adds the standard 12-card version to the existing 9-card game. (I like playing the 12-card game on easy mode because it’s fast.) Play with the basic Clades cards, with the Clades Prehistoric cards, or with a mix of them. Clades Solo feature’s Karen’s lovely art and plenty of science notes for players who love biology and evolution. The app is now free, so tell the teachers, scientists, and animal-lovers you know about it. Check it out!
