Dual N-back is currently the premiere brain-training task, by which I mean it's the only one that's ever looked at all promising for general benefit. Unfortunately, the newest and best studies suggest that even n-back performance is basically just a training effect on a single test, plus possibly improvement in visual processing. (In layman's terms, your memory doesn't improve, but you do get better at carefully watching for a dot.) This isn't being advertised as more substantive than dual n-back, just more gamified and playable. Given that n-back doesn't seem to work even if you're absolutely diligent about doing it, my expectation for "less rigorous but more playable" is that it will have no value whatsoever. https://www.gwern.net/docs/dnb/2013-colom.pdf https://www.gwern.net/docs/dnb/2013-colom.pdf
