New

Learn maths strategies and explore your progress

  • Learn mental-math strategies through step-by-step lessons, then play a matching practice game.
  • Explore your skills in the updated Stats area. See which types of maths questions you’re getting better and faster at solving.
  • Keep an eye out for noteworthy results after each round.

New look and feel. Same familiar game.

  • SumNinja now has a warmer, clearer design that makes it easier to find your next game and follow your progress.
  • Daily Sessions give you a simple practice goal, a focused play screen, and a useful recap when you finish.
  • Play modes, player tools, settings, Help, and Progress now work together more consistently across screen sizes.

A calmer way to play every day

  • Choose a time that fits your day. Pause or skip when you need to.
  • Finish with encouragement, a daily streak, and one useful idea for what to play next.
  • Speed and Accuracy are still ready when you want a challenge. Every result now appears together in Progress.
  • New players begin with addition and subtraction. Harder questions appear gradually as SumNinja learns their level.

Back up your progress and move it between devices

  • Import / export lets you back up your player data and move it to another phone, tablet, or computer.
  • You can also merge progress from multiple devices, so your stats show a more complete picture of your math practice.

Play together without mixing up anyone’s progress

  • Players now have a name, emoji, and color, so everyone can keep their own progress.
  • Multiplayer lets friends take timed turns on one device. Choose own-level or same-question play, then see who answers the most correctly.

Shape your questions and see your skills more clearly

  • Choose different sizes for the first and second number in your practice mix.
  • Progress now shows a cleaner skill map for your practice.
  • Rounds now start more gently and settle near your level faster.
  • Home and Settings also make it quicker to jump into practice.

Switch challenges without losing your progress

  • Modes are now easier to switch mid-round. Speed and Accuracy sit side by side, and you can finish a round early while still saving your progress for stats.

Jump straight into the skills worth practising

  • Suggested skills are now integrated into both Home and Progress. Tap a skill to jump straight into focused practice, and save your current settings for later.

Celebrate progress with achievements in 14 languages

  • Achievements have arrived! Earn them for streaks, speed, and daily play. Each achievement has its own icon and progress bar, and fun popups appear when you unlock one. SumNinja is also available in 14 languages.

See where your maths is improving

  • Your stats just got a big upgrade. You can now see how your skills improve over time, when you’ve practiced most, and where you’re getting faster.

A brighter SumNinja that fits every screen

  • SumNinja has a fresh new look! It’s cleaner, brighter, and fits any screen perfectly.

Keep playing anywhere, even without internet

  • SumNinja now works even without internet — perfect for playing on a plane or anywhere offline. It also loads faster and saves your progress automatically.
