FAQ
- How is the score counted?
- Your score is the streak of correct rule-following answers in one run.
- Do I need sound on?
- Yes. One channel is spoken aloud, so play with audio enabled.
- What if the word and the voice disagree?
- That is the point. Obey the current rule, not whichever cue feels louder.
- Is this a clinical Stroop test?
- No. It is a game that borrows the interference idea, not a medical protocol.
