Puzzle Tournament Rules

Competition Start

Puzzling will begin at 1:30 PM sharp for both categories! No puzzling will be allowed before the designated start time.

Puzzles will be secured in a bag until the timer begins. The bag may not be altered or opened before this point or the competitor will be disqualified.

Once the timer begins you may open the puzzle and begin puzzling.

Once puzzle boxes and pieces are opened, piece bags should be kept by the competitors in case a piece(s) was accidentally left inside.

Tools

Additional lights and sorting trays are allowed during the competition.

All other tools such as puzzle scoops, spatulas, magnifying glasses, and extra print outs are not allowed.

During the Competition

Team members are welcome to bring snacks and beverages of their choice.

Although we encourage a fun afternoon, please refrain from loud conversations, moving or standing in other team's space, and anything else that might impede another teams progress.

Puzzle Completion

As you near completion, a team member must raise their hand to alert a judge.

Once the puzzle is completed, all team members must remove their hands from the table and a judge will verify completion and record the time.

Lost Pieces

If a judge finds a piece on the floor during the competition, they will slide a bright piece of paper underneath the piece. This will highlight where it is so it doesn’t accidentally get moved further, but prevents it from being given to the incorrect team.

There is a maximum of 10 second penalty for missing pieces. Penalty is not per piece. If you have a missing piece, judges will note the time of the last assembled piece and the puzzlers will have 10 seconds to locate the missing piece. If the piece(s) is located, the completion time will reflect the time the last piece is assembled. If the piece(s) is not located within that time a 10 second penalty will be assessed.
