One emoji-themed mini-game plus 16 human benchmark tests. Everything is playable on-site, no sign-up needed, and your scores stay in your own browser. Away from the games, the site is a reference for emoji copy and paste: each of the 1,925 symbols has a copy button next to its character and its code points.
