Study & Practice
Filter by course, topic, and lecture — then browse the study guide or start a practice quiz. Untimed by default, no glucose, no stages, just questions — turn on a timer below if you want the extra pressure.

Custom run
Pick any mix of Course, Topic, and Lecture — leave a whole group unchecked to include everything in it. Since a mixed run doesn't have one storyline, stages are generic and life just shows as "Life" instead of a themed resource.

How to play
Objective
You're running through the bloodstream. Steer into topic blocks (←/→ or A/D, swipe on mobile) to trigger a multiple-choice question from that topic. Answer enough questions correctly in each required topic to clear the stage — there are 3 clinical stages total.
Life
Controls
←/→ or A/D — switch lanes 1–6 — pick an MCQ option, Enter — continue after answering P / Esc — pause
Study guide
Every topic and item you'll be quizzed on is browsable any time from the 📚 button — before, during (it pauses first), or after a run. If there's more than one theme, tabs appear to switch between them. Each question you answer also links back to its study guide entry in your session summary.
Study & Practice mode
A separate, untimed way to study: pick a theme, optionally narrow to specific topics and a course, then either browse the filtered guide or run a practice quiz — no glucose, no stages, just questions one after another with immediate feedback. End it anytime to see your summary.
Group Race
Race friends on separate devices — one hosts and shares a 5-character room code, everyone else joins with it. Same rules as solo Runner mode, but everyone is ranked by score once all racers are done, and you can see a live leaderboard in the HUD while you play. Elimination pops up a notice for everyone still racing.
