Download of BlockCode 2.2.3 for Mac was on the developer's website when we last checked. We cannot confirm if there is a free download of this app available. The software lies within Developer Tools, more precisely Webmaster Tools. This free software for Mac OS X is an intellectual property of WYC. We recommend checking the downloaded files with any free antivirus.
From the developer:
BlockCode is a graphic programming for children. The tool is designed to help users quickly grasp the programming concepts of variables, functions, parameters, conditional jump, cycle, array, string, etc., improve their hands-on ability, get real programming experience, and quickly cultivate programming thinking.
The problems are solved in the editing area.
