About Brain vs Math

Brain vs Math is a free daily math playground. The idea is simple: your brain is up against the numbers, and two focused minutes a day is enough to keep winning.

What's here

• Daily Target — the flagship puzzle. Six numbers, one target, five tiers from Warm-up to Expert. Everyone in the world gets the same board, and a new one drops at midnight.
• Math Sprint — a 60-second adaptive speed round. How many can you solve before the bar runs out?
• Times Tables — an interactive 12×12 chart with study lists and a quick-fire quiz.
• Worksheet Generator — free printable practice sheets with answer keys, for teachers, tutors and parents.
• Percentage Calculator — three everyday percent tools that show their working.
• The blog — practical mental math technique articles.

Our principles

• No accounts. Your streaks and stats live in your browser, on your device.
• Free to play, free to print. Worksheets carry no watermarks or limits.
• Fast everywhere. The whole site is hand-built, dependency-free HTML/CSS/JS — it loads in a blink on a school Chromebook or a five-year-old phone.
• Same puzzle for everyone. Daily boards are generated from the date itself, so your result is comparable with any friend's, anywhere.

What's new

New tools and worksheet topics get added regularly — recent ones include the ratio calculator, money worksheets and telling-time practice. More daily game modes and worksheet topics are in the works; the blog is the best place to watch for them.
