• Play at your own risk.
• Player contact: All players must only compete for the ball. Do not direct actions towards other players.
• No unnecessary roughness: No striking, kicking, dangerous tackles, blindside blocks, or targeting the head or neck.

1. Play on a solid elevated surface with no holes or slits.
2. Split teams from 1v1 up to 4v4, or play free-for-all.
3. Start in staggered positions with equal numbers of opposing players on each side of the table. Once the toss is up, players can move anywhere.

Offense / Tossing Team

• Expand the cannon completely and load the ball before every toss.
• Spiral the loaded cannon at least 10 feet high onto the landing zone to stack ribs and pop the ball out.
• Compete to snag the ball in the air or on the table. A ground-ball is also good for the offense.
• Players cannot touch the cannon while it is on or above the table.

Defense

• Compete to snag the ball in the air or on the table. Don’t let it reach the ground.
• Players cannot touch the cannon while it is on or above the table.

Teams alternate tossing after every play.

• Live: A play is live when the cannon lands accurately on the landing zone and the ball successfully pops out.
• Dead: A play is dead when the cannon hits the table edge, misses the table, or the ball remains inside the cannon.
• Fault: If a player’s first toss is dead, they are allowed one re-throw.
• Stacked Rib: A rib is "stacked" when an inner rib is completely collapsed and the cannon remains on the table.
• Foul: Touching the cannon on or above the table can result in a re-throw.

Offense / Tossing Team

• Stack: +1 for each fully collapsed rib on the cannon. The cannon must remain on the table.
• Ground ball: +1 if the ball touches the ground.
• Snag: +2 if the Offense snags the ball in the air or on the table.

Defense

• Snag: +2 if the Defense snags the ball in the air or on the table.

Use cancellation scoring after every toss. Play to 11 or 21, and win by at least 2.
