Coding & Game Development

35–50 min + optional 15 min

Work at your pace. Take a break between stages; there is no countdown.

You need: paper, a pencil and this lab. A helper is welcome for reading and discussion.

Connect to what you know

Combine the event, condition and repeated turns into your first playable game.

Understand it, step by step

  1. 1

    A game needs controls, a goal and feedback. Our board uses arrow buttons; reaching the star wins and touching a wall stops that move.

  2. 2

    A designer chooses the star and walls. A player needs a possible route. Difficulty should come from an interesting choice, not an impossible map.

  3. 3

    Testing means playing your own rules. Save a first design, try it, change one wall, and test again. A helper can play too, but is not required.

Watch a worked example

Put a star at the top right. A wall in the middle creates a detour. A solid wall across the board blocks every route: the goal is visible but unreachable.

Pause and predict

Can you trace a route before playing?
