Grids of Thermometers – a puzzle that must necessarily add to the collection of all who love, for example, Sudoku and other varieties of such games. This project is very much like the original source, while it has not only a nice visual display, but also a deeper process. Here you will fill the thermometer scales of different colors to match the specified parameters. A simple task in the initial stages very soon turns into a really serious test for the brain and attention of participants. So anyone who likes deliberate actions should try out this game.
