Elemingle

Elemingle turns the periodic table into a deck of illustrated cards. Every element has its own cartoon character, drawn by the artist Jean Estevez (Art Toon), and its card lists the atomic weight, boiling point, melting point, electronegativity or density, plus three short lines of trivia written as the element talking about itself. What a card never shows is the atomic number.

There is one Mystery Element a day, the same for everyone, and each day's game is numbered. The deck comes shuffled. For the card on top, you swipe left if its element is lower in atomic number than the mystery one, right if it is higher, and up if you think it is the answer. Each correct higher or lower call narrows the range, which the periodic table beside the deck shows with coloured borders and greyed-out squares. You can also type a guess straight into the Guess answer form. The aim is to find the element with as few mistakes as you can; there is no give-up button.

The game is made by Trainwreck Labs, a studio of free daily educational games. A short demo deck teaches the swipes the first time, a profile page keeps your plays, wins and streak, and a Practice mode gives unlimited extra rounds. The game can be switched to English, German, Spanish, French, Italian, Dutch, Polish, Portuguese or Romanian. It suits chemistry students and anyone who likes Elementle but would rather read clues and narrow a range than compare table columns.
