This is the solution:

ABC…

123…

123…

no/yes

no/yes

Each attribute has different values on the Ricca cards:


1	Josi	3	2	no	yes
2	Moni	3	2	no	yes
3	Kili	2	2	yes	yes
4	Beni	2	2	no	yes
5	Lori	2	5	no	yes
6	Phil	2	2	no	yes

The "X" and "✓" values of wings and teeth are represented with the type no/yes. The names Josi, Moni, Kili, Beni, Lori and Phil with the type ABC…. And the values 1, 2, 3… of eyes and legs , with the type 123….

If all values are written correctly and with the same type, the collection can be sorted by any attribute.
