How to play

1. Each day has a daily set of 10 questions. When it's done, you can keep playing in practice or replay the set.
2. Pick a mode: Easy 1x, Hard 2x or Speed 3x. Today's mix rotates through all three.
3. Answer fast and build a streak for more points.
4. Wrong answers and timeouts lose points: Easy −5, Hard −10, Speed −15.
5. Calm mode adds 5 seconds per question and turns off the countdown sound.
6. Keys: arrows to move, Enter to choose, 1–4 to answer, Esc to pause, M to mute.
