Quarters can be played with any number of players. You need just a table, a quarter and a glass (or somtihing simular)
Beer / Longdrings / Shots
Quarter or soming simuar and a table
You sit around a table (hard wood works best). Place the glass in the middle of the table and someone start and try to bounce the quarter off the table and into the glass. If the quarter goes into the glass everyone except the shooter have to drink. The the next person try to bounce it into the glass.
To make it more intressting you can add some extra rules like if the shooter dont hit into the glass he ahve to drink or something like that. Have fun!
