There are 148 challenges for you to test on. But no worries, there are "Lifelines" provided to help you complete a level. You can even get a lifeline when you already used the defaults provided, all you have to do is to play another memory game, and that's it. By getting a lifeline, it will not just improve your short-term memory but will also improve your mental calculation, focus, and concentration.
How to play instructions are provided in the game.
Statistics are also provided for you to see how do you do in each level (how many seconds did it take to complete, lifelines used, and how many attempts to complete).
Play now and see how far can you get, the more you play the better results you get.
