From the back of the box:
"JAG-GER is the first true family game in years. Children compete equally with adults. The puzzles are hexagonal in shape and fit on a tray board. The difficulty level of each board is determined by two factors: the number of pieces in a puzzle - 25, 50, 75, 100, 150, 200, 250, 300 - and the difficulty of the puzzle picture - Levels 1-5, 5 being the most difficult. Refill puzzles are available for all ages and skill levels. With every purchase of a refill, JAG-GER is a new game".
Contents listed as 54 score cards, 2 game boards. 2 puzzles (each are 100 pieces). The box bottom of mine shows a beautiful mountain lake photo with flowers in the foreground and a photo of a Germanic/medieval looking building beside a canal with a covered bridge.
With more than two players, players play in teams. Box copy on some editions suggested playing with up to six players.
