The irRegularGame of Life is based on Conway's famous "game of life" - a 2D cellular automaton that has interested computer scientists and nerdy types for decades. You will be amazed by the fascinating grid patterns that evolve from 4 simple cell rules.
Some suggestions:
-Levels can generally be solved with a combination of logic and some educated guessing (look at the level names and starting patterns)
-Some levels have only one solution, others have many
-Even if you don't enjoy the puzzle game mode be sure to play around with the Sandbox.
