It also states "We then evaluate your game scores and use a proprietary algorithm to derive your BPI" Performance on almost all cognitive tasks are intercorrelated to some extent, and if you take the average, or preferably the first principal component, of a battery of cognitive tasks, it will tend to have a general factor, which will have some loading on g.

Each game is on a timer. That forces an intense burst of concentration and mental effort. That mental effort is what strengthens my brain and makes it more powerful. After each game, I receive instant feedback on how well I performed. Statistics include reaction time, total missed and correct, my previous high score, and an evaluation of how much I improved. These games are not easy! If they were, your mental skills would not be strengthened by playing them.

You must hold the vanishing symbols in your working memory during the timed session. Scientific research has shown that working memory is closely linked to how intelligent you are, and that working memory can be improved.
