Important notes

  • Enter only the verified value, then use the on-screen confirmation control when the puzzle provides one.
  • Do not add extra actions after the verified answer; many Brain Test puzzles punish an otherwise sensible second move.
  • Question order can change after an update, so match the wording and screenshot instead of trusting the number alone.
  • Restarting the level restores moved objects and counters if an earlier experiment changed the puzzle state.

Why this answer works

Set the number of siblings to 6, as the five brothers share one sister, and tap submit. The puzzle rewards attention to the exact wording and to objects that can be moved or tapped, not a complicated calculation.

Useful solving habits

  • 1Read the prompt literally before applying real-world assumptions.
  • 2Test whether text, labels, and decorative objects are interactive.
  • 3Use the simplest gesture that matches the verified answer.
  • 4Compare the success frame with the screenshot if the result is unclear.

Collectibles and completion
