Spaz
Spaz is a way fun game played around a pool table. It involves running, and flinging pool balls, so it might be best if you played around a not-super-nice pool table that has plenty of space around it.
Sock
A good group game, played indoors or outdoors. One player sits in the middle of a circle and tries to grab a balled-up sock the rest of the players pass around secretly.
Name that tune
A classic guessing game involving music. Use an iPod (or CD player or tape player or record player…), or a computer, a piano, or your voice, then play part of a song and get others to guess the name of the tune.
The human knot
A fun game for on land or in the pool, one I often played with siblings and cousins. Players stand in a circle, grab hands, and form a giant human knot that everyone tries to untangle together.
Questions Only
A funny talking game for a group. Players try to communicate using only questions. But it can be more challenging than you think!
