To whoever recommended Kapla bricks...

[wrongway]

THANK YOU! They are amazing and my DS (6) plays endlessly with them. They are the perfect outlet for his creativity and his endlessly enquiring / designing mind.
I highly recommend them!
Also great that they are not bright, mixed colours as he likes building with uniform, 'real' bricks.
We are buying more and more of them as he wants to build bigger and better things.
I find this forum so helpful. Thanks everyone!

We bought four boxes of janga bricks instead, it was cheaper than kapla

I agree they're not cheap but they are so worth it considering the hours and hours of play we get out of them. I think they're a lot more versatile than jenga as they're much slimmer and lighter and you can build intricate, life like structures.
I'd never heard of them or seen them anywhere, and doubt I would have without Mumsnet
