Simple, fun, but hard to master!
I love games from this company. They're fun, you don't need wifi to play, and there are no ads! It's fun thinking about the different combinations you have to think of. It's a great game that uses strategy, planning and lots thinking to get the code! Not only that, but you can make the game harder by allowing repeat colors, or empty spaces into the code. You get a lot of tries to guess right too. I recommend playing this game for car rides, or passing the time. I have it with some other apps that I use when I have no wifi.
