Ten brain-bending games built on the same cognitive pillars real IQ tests use. Sequences, memory grids, mental rotation, Stroop traps… can you score 100%?
Ten games. Each one trains a different broad cognitive ability. Tap any to play solo.
🔓 All games are 100% free. Sign in with Google to save your scores, track daily progress, and build your Cognitive Index.
No. Every game is completely free to play right now. Creating a free account lets you save your scores, track your daily streak, and build a personal Cognitive Index across devices.
No — and we'd be suspicious of any free website that claims to be one. These games are mapped to the Cattell–Horn–Carroll model that underpins modern IQ assessment, but your Cognitive Index here is a practice score, not a clinical measurement.
The full Daily Workout runs all ten games in about ten minutes. Individual games take 60–90 seconds each.
Difficulty adapts to you. Every correct answer pushes the level up, so perfect accuracy is rare — and a real flex. Most players plateau around level 5.
Yes. The whole experience is built mobile-first. Tap, drag, and play — no app to install.
Your scores live in your browser by default. If you sign in, they sync to your account. We use lightweight analytics with opt-in consent — you control what's tracked from the footer.
Testing my IQ is a training tool for practice and self-improvement. Your Cognitive Index is an estimated performance score based on how you play today — it is not a clinical or diagnostic IQ measurement. Real cognitive assessment requires a licensed professional.
