How to play

  1. Watch the signals

    Press A, S or D, or use the colour buttons, as each signal reaches its target zone.

  2. Remember the sequence

    Study the letters, then choose the matching sequence with Q, W, E or R, or the on-screen choices.

  3. Keep the maths moving

    Solve the arithmetic while continuing to monitor the other tasks.

Scoring

Accurate signal responses earn 100 points, correct memory sequences earn 250 and correct maths answers earn 150. Errors and missed responses can deduct points.

Tips

  • Scan all three tasks in a repeatable order.
  • Group letters into smaller chunks.
  • Return to the signals after each response.

Unlocking levels

Beginner is available from the start. Reach each target in a single completed three-minute round at the previous level.

  • Intermediate: score 6,000 in Beginner.
  • Advanced: score 8,500 in Intermediate.
