The Ravensburger Krypt Neon Green puzzle presents a special challenge for puzzle fans. Instead of a classic picture motif, this game features 736 solid neon green puzzle pieces. Orientation is based exclusively on the individual shapes of the pieces and the spiral die-cut pattern. Thanks to Softclick Technology, the individual cardboard pieces fit together precisely. This single-color challenge puzzle is ideal for experienced puzzlers who want to put their patience and combination skills to the test without a printed motif guide.
