"We spotted these boards at Legoland and my 6yo bought them with birthday money. He is absolutely thrilled with them. They connected easily and they are providing extra inspiration for his play (not that he usually needs any).
The boards are square, but because they don't have lego studs on them, its easy to arrange the lego builds onto them. They are sturdy card with different designs on each side and with a connector space in each corner, making for great flexibility in designs for play. They are holding together well on our carpet, which is so helpful.
We bought a grass set and a sea set... my son has already requested that he has more for christmas.
Great addition to the range Lego, please bring out more... maybe space theme, and pieces with larger beach areas!"
