How to Play FollowKey
Do you know Simon Says game? Use this memory test to see how many items / sequence you can remember, the game itself is very simple: Just echo back all keys that computer shows to you! Hit key sequence one by one exactly in same order as first appearing on the screen. In the very begin you need to hit just one key, next step is 2 keys and so on. Finally game ends when you are not able to memorize more and you will see how many units your working memory was able to store.
Tips: Try to memorize key sequences (pseudo words like AADF DDJK) instead of individual key hits. You can also choose the keys to train in this game from the select difficulty drop-down menu located on bottom right.
