Ten levels from Rookie to Master. Level 1 is just E and T — six questions, 25 seconds each. Level 10 is 30 questions at 8 seconds each. Levels unlock as you pass them. Your best scores save to your device automatically.
Each correct answer scores 100 base points. Faster answers earn a speed bonus — up to 50 extra points depending on how much time is left. Wrong answers score zero. Perfect score on any level is 100 × number of questions + speed bonuses.
