Rank-up celebrations
When a completed run or new personal best moves your Lab Rank into a higher tier, the site shows a brief local rank-up celebration. Existing users are not given retroactive celebrations when the update first loads.
Local progression
Lab Ranks
Build your Lab Rank by completing challenges, setting difficulty-specific personal bests, and taking on harder modes. Your rank stays in this browser.

Medals complement Lab Rank
Lab Rank reflects your broader activity across the site. Challenge medals show the highest difficulty completed on each individual challenge.

Category ranks use smaller thresholds because each category contains only part of the full challenge library.
How rank points work
Every completed run earns a small number of local rank points. Beginner runs earn 3 points, Standard runs 5, Advanced runs 8, and Expert runs 12. Setting a personal best for a challenge at a difficulty also contributes a one-time bonus at that difficulty.
Lab Rank is deliberately separate from the 0–100 Performance Score. The Performance Score continues to use Standard-mode personal bests so the baseline remains consistent. Rank reflects participation and difficulty progression rather than claiming to measure intelligence, health, fitness, or general ability.
