How to play

  1. Choose which operations to practise and how hard the sums should be.
  2. Press Play and type each answer. It is checked as you type, so there is no need to press Enter.
  3. Keep a streak going: every correct answer in a row adds a bonus. Skip a sum you cannot solve.
  4. When 60 seconds are up you see your score, accuracy and best streak.

Tips

  • Start on Easy to learn the rhythm, then move up.
  • Learn tables up to 12 and squares up to 20. They make Medium and Hard much faster.
  • For addition, add the tens first and then the ones.
  • A skipped sum costs your streak but saves time on a hard one.
