Saturday, Febuary 21st, 2026

2:00-5:00 PM

Platte Community Building

310 Main St in Platte, South Dakota

2 Person Team - 500 Piece Competition

4 Person Team - 1000 Piece Competition

The tournament is limited to 25 two-person teams and 15 four-person teams.

Prizes of Cobble Hill Merchandise will be given to the top 3 place finishers for the 500 piece and 1000 piece divisions.

Puzzling will begin at 2:00 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. 

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.

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. 

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. 

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.
