| amcbeth | 7 | 3 | No | Items on the cards match, but no two cards are identical, making match-finding more conceptual. The cards can be used for various games provided in the rules, as well as improvised categorization games. |
| christiankilloran | 6 | 4 | Some | A pretty good game for younger children, especially if they already enjoy the I Spy picture books. |
| pikkusiili2000 | 6 | 2 | Some | By limitng the cards and just using it as a matching game my 2 year old loves this game. |
| Scammer | 6 | 4 | Some | As far as memory games go, this one is at least pleasing on the eyes. It's amazing how much better young kids are at memory games as their adult parents! My 5 year old can easily beat all comers. |
| beauka | 4 | 3 | Some | Yet another Memory variant. At least with the I Spy series you can appreciate the time and effort put into making the cards. |
