I'm pretty sure you might have heard of this game before but here is how it goes. The first person has to say two things that are true about themself and one lie. The next person to comment points out which one is the lie then says their two truths and one lie. 

For Example:

Person 1: Princess Luna is my favourite princess, I like playing soccer and I hate sushi.

Person 2: You hate sushi(the lie). My favourite colour is orange, Lyra Heartstrings is my favourite background charatcer and I have been to Paris.

Also if they get the lie wrong than the person can point out the real answer to them by replying.

Have fun!

PS: Trust me this game is much easier on the internet. I have played it in real life and whenever I say my lie I instantly look suspicious. XD
