What this template contains

  1. step 1 · Switches

    Restore power

    🔋 Five power cells, numbered 1 to 5 from the left.

    📝 The engineer's note says:
    'Even-numbered cells are flat. Switch on every cell that still has charge.'

  2. step 2 · Grid 4x4

    Seal the leak

    🗺️ The module map is a 4 by 4 grid.
    💨 Air is escaping from every square that touches no edge of the map.
    🛠️ Select them all to seal the leak.

  3. step 3 · Direction (8 ways)

    Steer the capsule

    🖥️ On your screen, up is north.

    🛰️ Fly the route mission control gave you: north-east, then east, then south-east, then south.

    🎯 Four arrows.

  4. step 4 · Numeric code (PIN)

    Dock

    🌍 Enter the Earth to Moon distance in thousands of km.

    📏 About 30 Earths fit in the gap, and Earth is about 12,800 km wide.

    🔢 Three digits.

Ideas to make it yours

  • Replace the Moon question with a fact from your current science chapter
  • Project the lock on the board and let the whole class vote on each answer
  • Turn the final reveal into the homework or the next lesson's starter

Questions about this template

Which skills does it practise?
Odd and even numbers, finding cells in a grid, compass directions and a multiplication that gives the real average distance to the Moon, about 384,000 km. It fits a science or maths lesson, or an end-of-term session.
Can I run it with a class of 30?
Yes. Share one link or show the QR code, and pupils play in teams on a phone, each team at its own pace. Nobody needs an account, so the game starts as soon as the link opens.
What happens if a team gets stuck?
Every step has an optional hint that nearly gives the answer, and a wrong-answer message that nudges pupils back on track. You can also rewrite any hint to match what your class has studied.
Is this template free?
Playing it and editing it in the builder are free for everyone, and players never pay. See current plans and features on the pricing page.
Can I change the answers and the texts?
Yes. Every code, clue, hint and piece of locked content opens in the builder, and nothing is saved until you publish.
What do players need?
A phone or a computer with a browser. They open your link or scan your QR code, and never create an account.
How long does it take to play?
About 35 minutes, from the first lock to the locked content.
