Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
132 words
A puzzle comprising a plurality of cards each having only a single through opening, said cards being configured for superposition in stacked relation with the opening of each card at least partially closed by the extension thereacross of certain of the remaining cards, and partial characteristic markings on said cards along the bounding margins of said through openings and extending to the edges of said openings, said cards being selectively oriented in said stacked relation with the partial marking of nether cards in adjacent complementary relation with the partial markings of superior cards, said openings each having at least one bounding margin which does not extend along an exterior bounding margin of the associated card, and said partial characteristic markings being along and extending to the edge of said one bounding margin.
Claim 2
Dependent Claim
