Objective

The goal of Leis is to eliminate all liquid in your opponents' pint glasses by scoring a total of 8 points (4 per glass). Points are earned by:

• Sinking the ball in a cup (2 points)
• Dinking the lip of the cup with an upward bounce (1 point)

Equipment

• 1 ping pong table
• 1 ping pong ball
• 4 paddles (1 per player)
• 4 pint glasses (2 per side)
• Beverage of choice (typically beer)

Table Setup

• Place 2 pint glasses near the back edge of each side, parallel to the edge and adjacent to each other.
• Each cup must be placed one paddle-length from the back edge.
• Corners of the table are labeled clockwise: α (top-left), ω (top-right), δ (bottom-right), θ (bottom-left).
• Side A and Side B are fixed scoring sides for each team.

Teams and Roles

• 2 teams of 2 players.
• Each team has a fixed scoring side.
• One player acts as the Setter, the other as the Scorer.
• During serves: one team has a Server and an Obstructor.
• When a team scores 4 points against their opponents, they switch sides and roles.

Serving

• The Server stands at corner ω.
• The Obstructor stands upright on the opposite side, one paddle-length from the back edge, torso nearly touching the table. They may not move during the serve.
• The serve must:
• Bounce once on the server's side.
• Reach at least nipple height as it enters the opposing side.
• Bounce once on the receiving side.
• If the serve hits the Obstructor, it is still valid.
• Faults:
• First fault: retry.
• Second fault (double fault): server's team drinks ¼ cup (1 point).

Gameplay and Scoring

After a valid serve:

1. The returner sends the ball to their setter.
2. The setter sets up the scorer.
3. The scorer attempts to score:
• Sink (ball in cup): 2 points, both opponents drink ½ cup.
• Dink (ball hits lip and bounces up): 1 point.
• Dink downward: no point.

Game-Ending Foul

If a player knocks over a glass during gameplay, their team automatically loses.

Victory Conditions

• A team wins by scoring 8 total points.
• A shutout occurs if one team wins without drinking.

Spirit of the Game

• No spiking (paddle angle must be < 90°).
• Obstructors with anatomical advantages (e.g., chest size) are tactically favored.
• All disputes (e.g., dink direction) are resolved by majority vote or common vibe.
• Honor the code of Leis. Be vigorous, not violent.
