Course description

• Flashes numbers on screen one at a time — you mentally track the running total and enter your answer at the end.
• Supports addition, subtraction with negatives, multiplication, and division — each building a distinct mental skill.
• Fully configurable: choose digit length (1–8), number of rows (up to 18), and speed from 8 seconds down to 1-second extreme mode.
• Voice mode reads each number aloud — perfect for eyes-closed practice and audio-only focus training.
• XP system with 10 levels from Rookie to Mythic, streak bonuses, and an auto-saved leaderboard to track personal bests.
• Five animation styles (Slam, Zoom, Glitch, Spin, Random) keep sessions visually engaging and prevent autopilot.
• No account needed. Runs entirely in the browser with progress saved locally — private, instant, always available.
