Sorry if replying to an old post is frowned upon but, I have been doing N-Back for a while now and have seen drastic improvements in my learning ability (problem solving?) at school. I'm in my late 30's and was born with learning disabilities (most people are). I know that at least 2 back has helped me.

The reason I'm replying to this post is that I did searches on youtube for Egyptian Ratscrew and the explanations of how to play the game didn't sound or look anything like Dual N Back.

N-Back involves recalling sounds and the position of a visual stimuli. Egyptian Ratscrew does not.
