Six dimensions, nine games and a weighting table. Here is how a handful of scores becomes a shape, and what the shape does and does not mean.
The ability radar is the feature people ask us about most, and it is also the one most likely to be over-read. It is a summary of how you have performed on this site. It is not a psychological assessment.
With that caveat, here is exactly how it is computed.
Each game loads onto several dimensions
Sudoku is mostly logical reasoning with a working-memory component. Memory Match is almost purely working memory. Minesweeper is reasoning plus a spatial element.
Rather than assigning each game to one dimension, we give each a weight vector across all six and let the scores distribute.
Percentile, not raw score
A Sudoku score and a Math Rush score are not comparable numbers, so we never compare them directly. Each game's score is converted to a percentile against other players of that game first.
Percentiles are comparable across games, which is what makes combining them legitimate at all.
Recency is weighted, but not overwhelmingly
Recent runs count more than old ones, because we want the radar to reflect how you play now. But the decay is slow enough that a single bad day does not move the shape.
This is why the radar feels stable even though it updates constantly.
What it does not tell you
It does not measure intelligence, and it does not predict anything outside this site. It describes your performance on nine specific puzzle games.
We would rather state that plainly than let a hexagon imply more than it can support.
