The goal is simple; fill the grid with 1s and 0s following the game rule. One simple rule: You cannot place more than three consecutive 0s or 1s next to each other.
Three levels of difficulty with grids ranging from 6×6 up to 14×14, including rectangular grids. All the grids are randomly generated for a virtually inexhaustible number of puzzles.
Smaller grids are great for younger players or if you just want a quick game. Larger grids will provide a challenge to even the best puzzle solvers.
Grids can be zoomed in and out using a spread and pinch motion to easily complete large grids even on smaller devices.
