Play TxtIQ freeHow a game works
- 10 questions per game, picked from 410 puzzles across seven themed packs.
- 3 difficulties: Easy (10 min, 5 hints) · Medium (5 min, 3 hints) · Hard (3 min, 1 hint).
- Hints eliminate two wrong answers; Skip moves on without penalty beyond the missed points.
- Explanations after every answer – the reasoning, not just right/wrong.
- No repeat rounds – questions you have already answered this session stay out of your next game, so back-to-back rounds stay fresh.
- IQ score from accuracy, remaining time, and difficulty – plus streaks and a personal best per difficulty.

Launch TxtIQTxtIQ FAQ – scoring, daily challenge, privacy
How is the IQ score calculated?
From three parts: how many of the 10 you got right, how much time was left on the clock, and a difficulty multiplier (Easy ×0.8, Medium ×1.0, Hard ×1.3). It is a game score for fun and self-tracking – not a clinical IQ test.
How does the Daily Challenge work?
Everyone gets the same 10 Classic Mix questions each day, picked by the date. Finish it to grow your day-streak; miss a day and the streak resets.
How do I unlock question packs?
Play more games. Space unlocks after 3 games, Animals after 5, Math after 7, Words after 10, Science after 15, and World Explorer after 20. Your total games-played count is shown on the pack screen.
Where are my scores stored?
Only in your browser. Nothing is uploaded, so scores do not follow you across devices – but nobody else can see them either.
Is it free?
Yes – the full game, all packs, and the daily challenge are free with no account.
