Students make pairs and get a set of vocabulary cards. The cards are split into 3 groups. They also get one ohajiki (a counter/game piece) each. Each student puts their ohajiki on one of the cards. The teacher sets a random time on the timer (between around 30 seconds and 2 minutes), but turns the timer away from the students so they can’t see how long the round will be.

The teacher starts the timer, and calls random vocabulary. The students repeat them. When the timer stops, the students check the final vocabulary they said. Any student who has an ohajiki on the card that matches the last vocabulary called wins three points. Any student that has an ohajiki on the same group as the last vocabulary wins one point. The teacher then sets a new random time and the students pick a new vocabulary card for the next round.
