We soon will be able to make an encyclopedia of Magformers clones – Magsmarters, Ginimag, Magic Piece, Mag-Wisdom, and, finally PowerClix by Guidecraft. The latter, although considered American, is still made in China. We checked out the first 2 clones – 100% match in quality and magnetic properties. Magic Piece is very similar to Ginimag. We liked PowerClix because of its magnetic sticks. In Mag-Wisdom, I personally liked the multi-page colorful mathematics album-manual, which I later found on Magformers site – you can download it and use it in a game with a building kit, pretty much like albums for Dienes blocks.
