alt Hacker NewsWhen I read the title the first thing that came to my mind were Magna Tiles. Glad they made it on the list.
It's the only toy in the house that lasted the test of time from she 4-8 (and counting). Also I love tidying up Magna tiles, even that is fun!
My oldest kid got a small sample of Clixco and was surprisingly entertained even with a limited set of possibilities they offered. They're great fidget toys as well.
I annoy my wife by sorting magnet tiles away color type AND color. I do it as fast as possible with mock sorting algorithms. She shoves them back into the box.
