Kapla

Plain, ordinary wood blocks that are all the same? Sounds boring, but my 4 year old, 9 year old, and visiting adults play with these far more than the standard block sets. The key to Kapla is that these planks are precision milled (with a laser?).

All of the blocks are exactly the same height,...more width, and thickness and all of the sides are exactly 90 degrees from the ones next to them. These fact lets you build incredible structures that are very stable including ones that are as high as a kid can reach. Though we have not achieved the level of some of the impressive structures provided in the galleries, Kapla keeps our kids busy and has allowed their creativity to flourish. Sometimes less is more.

I hear this competitor is just as good if you run across them: Keva Planks
