Learning the symbolic language of chemistry is a difficult task that can be frustrating for students. This article introduces a game, ChemOkey, that can help students learn the names and symbols of common ions and their compounds in a fun environment. ChemOkey, a game similar to Rummikub, is played with a set of 106 plastic or wooden tiles. The object of ChemOkey is to create the formulas and names of ionic compounds from tiles on which the names and formulas of common cations and anions are written. With ChemOkey, students can learn the symbols and names of common ions and acquire a level of familiarity with the electroneutrality principle and the names and formulas of ionic compounds.
