Query: Good looking toy, difficult to play

This is a nice, colorful toy, but when it comes to play, it does not work so well. The blocks do not stay on the pattern and slides away with slightest shake, so kid has to be very cautious when placing them. Apart from that, the blocks are really good and my son loves playing just wih different shapes and placing them on floor. It would have been nice if board had some grove or sticky pad on which blocks can be placed.
