10. Twenty One
This a favourite drinking game so if you’re an adults-only group this can work that way. Or if you have kids in the group you could do it with hot chocolate. Or remove drinks altogether and just do it for fun.
You need at least 5/6 people for this to work well. The aim of the game is to count from 1 to 21. Each player can choose whether they say one, two, or three numbers in the sequence. And each of these has a consequence in the direction of the group counting.
If a player says one number the play continues in the same direction. If they say two numbers, the direction of play reverses. If they say three numbers the play skips the next person – or jumps over them.
If you make a mistake in the drinking game you take a swig. Drinking or not, you start again from one.
Once you get to 21, the person that says 21 gets to add a new rule for the next round. It can be anything they like, but examples could be that you have to stand up on any number divisible by 5, or you have to clap on every even number.
