Actually this is not a game, it is more of a playable virtual toy. There is no winner, no loser, no objective and no points. It is intended for small kids. No reading skill is required. But even adults can find it engaging. The goal is to allow the user to freely express imagination and creativity. One can build anything using chosen blocks. Program simulates realistic physical environment with gravity and mass, so it teaches some basic mechanics on intuitive level and it also aids in development of hand-eye coordination. If there is not enough or too many blocks one can open a menu (right upper button) and add some more or remove some not needed. To add a new block (there is upper limit on that) simply drag a new block from menu and put it somewhere. To remove a block drag it into upper trashcan. To clear all blocks click bottom trashcan (the one with an explosion mark). To change color (before picking a block) click one of the colors in menu. Blocks For Kids is intentionally made simple, so there are only few block types and colors to choose from. For more fun there are three modes of gravity: normal, strong and low.
Please note that the program is intended mostly for tablets. It will work on smaller screens, but the experience may not be satisfactory.
