Grimms Square Puzzle

What can i say,

I bought this for my 4.5 year old who has developmental delays in many areas, we got this so he can work out problem solving skills and to work on his concentration (he can only follow 1 step instructions at this curremt stage) plus fine and gross motor and he loves it he sits down trying to create different ways to manipulate the puzzle and is trying his absolute best to concentrate on it

Lovely Grimms Piece

This has been my first experience with the Grimms blocks - they are lovely to see and touch. They still have the texture of raw wood even though they’ve been coloured. The puzzle is great and can be arranged in lots of different ways. The only thing that annoys me a little is that the pieces don’t fit “snug” in the frame - there’s a little too much room so they slip around. Apart from that, love it!

Great for all ages

This puzzle was a gift for Mr 4 and he loves it. We added the cards that come with a range of ways to set up the puzzle all varying difficulty. They wooden tray provides a place to build the puzzle whether it’s flat or a tower. We have also had fun stacking it. As usual the Grimms quality is amazing!

Great puzzle

This has been a fantastic puzzle for my 6 year old too work out. It’s not too hard for her, but isn’t too easy either. And then best of all the blocks can be used with their other items to build with.
