BLUE in metal box

The 1-piece box contains one of the 5 different puzzles

On one side is the puzzle, and on the other, the game. Blue consists of five almost identical puzzles. However, each puzzle differs in a few small details. For example, the motifs are colored differently, or one or two of the motifs are missing a small detail.

Blue can be played individually or in a group. But it's especially fun with three to five people. The puzzles are placed face down on the table. Each player receives a starting piece. This is marked with a letter on the game board. Now it's time to put the puzzle together. Everyone tries to complete their motif. But all the pieces fit together, even if they're their opponent's pieces. This is where the initial excitement begins. But then, after the puzzle is completed, the second round begins. "You have my piece!"

The first player to complete their puzzle receives the corresponding number of points. The remaining players receive fewer points. In the second round, the goal is to optimally swap the puzzle pieces to create a correctly colored puzzle. Points are deducted for each swapped piece. Other game variations are also possible. Missing pieces are simply deducted as points (W. Just, 2007, ratgeberspiel.de).
