About this app

Puzzle Black and Red is the original game where figures have two bits states. You can switch the state of the cell by touching it. But the state is changing not only in this cell, but also for those with whom it is connected. Puzzle Black and Red is a simple but an exciting puzzle. The rules are simple: 1) There are cells in two colors. 2) Tap on the figure to change its color to the opposite. The color will also change the neighboring figures, with which it was connected. 3) Remove all red cells from the field! 4) Try to do it in a minimum number of moves. There are 3 categories of difficulty. Each categorie has 300 levels. There are total (3x300) = 900 tasks. The "Solution"-button is available for all tasks(puzzles). No limit. The game has an undo move button. Save/Load game state.
