    How to play

    Every day you get five tests, one of each kind: Reflex, Aim, Brain, Timing and Words. Everyone gets the same five tests on the same day, picked from a pool of twenty, so you can compare scores with anyone.

    Each test gives you a time in milliseconds. Your score is the average of all five, and lower is better. Each test is also rated sharp, steady or sluggish against its own par.

    You get one run a day. Leave or reload in the middle of a test and it's scored at its time limit. Mistakes cost time; they never end the run.

    Hard mode is a second daily run of the same five, turned up. Practice lets you play any test as often as you like, the archive replays past days, and the weekly marathon runs all twenty in a row.
