Playing sudoku causes brain damage.

INSUFFICIENT LEANING
Recorded sources
0 sources for · 2 against

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that playing sudoku causes brain damage?

Unclear. Two neuroimaging reviews describe sudoku as recruiting normal frontoparietal and executive brain networks, offering partial evidence against the idea that playing sudoku causes brain damage; no retrieved source directly tests or reports harm from sudoku.
