If the student is correct then they can choose either their row or column to sit down with them, if the student is incorrect then nobody gets to sit down. Continue the game until everyone sits down.
Feel free to adapt the game to suit your students and teaching style.
Here are some examples of statements I use when playing this game of truth and lies [throwing a few funny ones in there is always a good idea]:
I live on the moon.
Today is the day after yesterday.
I am older than you.
Tennis balls are square.
I wear shoes on my hands.
Hours are longer than minutes.
All girls have short hair.
We are not outside.
I have blonde hair.
Tokyo is in Japan.
I am friends with Tom Cruise.
