You need one die, 4 cups, 4 players, 4 chairs, lots of beer, and a modified ping pong table(no net). You can't say 5 or 7, nor roll a 5.
Basic rules are 2 players per team. Everyone has a full cup of beer (16 oz+), two players per side- each side is a team. Each player puts a beer at arms length along the border of the board (by where the wrist sits), and that beer must remain there for any shot. First team shoots. Die tossed needs to go as high as the length of the table (from the ground). You aim for the opposing cup. If it does not go that high, it is an illegal shot and shooter forfeits toss. If it lands in cup both teammates on side where dice splashed need to chug their full beer. They leave die in cup, and spit it out on the table when done chugging. If it is a 5- enjoy another. If any toss stays on table and is a 5, your team owes a full beer.
Tossing the die requires a lot of skill. But the whole game is catching it. The point of the game is to catch the die if it ends up bouncing off your side of the table- with only one hand (and no traps). The dice bounce wicked and it is a challenge. The way you point is if the die lands on your opponents side of table, bounces off, and neither of the opposing team catches it. That is one point- you usually play to 7 or 10. Some versions of this game have many, many other rules, but that is the basic idea.
Great fun!
