Two 75-card halves each contain one card from every icon pair. The end bars on the partition row identify the half.
Choose either half for a complete set of 75 different icons, or combine the halves for matching pairs.
Icon Halves were added in v2 as the third signal on the lower rail. The filled-symbol count gives the partition value, the symbol shape identifies the icon group, and the end bars identify the icon half.
Choose one half when every picture should be unique, or combine both halves for memory and matching pairs.
Use the halves as teams or alternate card pools. Either half also provides a 75-card deck with ranks 1–15 in each of the five suit colors.
Each icon appears once in Half 1 and once in Half 2. Icon Half is separate from the 1-5 Partition value.
Each half also contains exactly one card for every rank x suit color pair. Either half forms a 75-card deck with ranks 1-15 in each of the five colors.
