About YES or NO, free game to challenge your brain

It has been brought to our attention that your current home address is the moon. This is the best test for you, as it will increase your attention and fast-reasoning skills. It's pretty addictive too, but you can deal with that, right?
This test is based on the Stroop Effect, a psychological phenomenon that describes the difficulty in naming the print color of a word when the text refers to an 'incongruent' color. This happens because your brain goes cuckoo when it sees an interference between the written word and the color it's is printed in. Crazy, isn't it?
By continuously performing this test and successfully completing it, you will learn to focus your attention in order to inhibit distracting information. You will become a Concentration Whiz in no time, PLUS have loads of fun and play against users all around the world.
