❓ FAQ
Is this the lab symmetry span?No. Lab versions control timing and item banks. This is a short original mix.
Does a long span mean high IQ?No. Dual-task toys are sensitive to strategy. Not a working-memory IQ.
What if I ignore symmetry?Then you are playing a different game. Still not a score you should put on a résumé.
