Mustache Smash is an absolutely awesome way to practice Reading, Listening & Speaking in your ESL or EFL classroom. It's very similar to the classic game Hammers, however Mustache Smash requires a little more space and a timer. In case you haven't noticed, we love using timers in our games. A timer instantly adds an extra layer of difficulty that we've seen help students get over any shyness they may be feeling time and time again.
