Snap Circuits are just standard electronic components that combine with each other using standard snap buttons [1] from the textile industry. The real “genius” of them is that the grid spacing and the width/thickness of each component is well-balanced such that they are held together securely while being easy to separate using the lever action that a child naturally produces when grabbing something (ie don’t pull straight up). It should be easily replicable and I’d be surprised that there aren’t knockoffs in all the countries that they block from their website.
