Web version:
http://davebren.me/menobackI've created a tetris-like block stacking game that adds n-back memory training by n-back matching block shapes and colors. From my own playing around with it, it's extremely challenging. It's very difficult to find the right state of focus and maintain it even at low n-back levels.
It's completely free and open source, if you have feedback or find bugs you can report them on the github issues page:
https://github.com/davebren/me-no-backI'll be packaging a desktop version as well.
If you train with it for some time, please tell me about your experience here, any benefits, what levels you are able to reach, and your high scores.
