Merlion Mail Run
Line up picture cards to steer a postbot around a grid, then press GO and watch the plan run. Suits P1 to P3. Teaches sequencing, debugging and the first idea of a loop.
What this teaches, and who it suits
Merlion Mail Run is a free coding game for Primary 1 to Primary 3. Children queue picture cards (forward, turn left, turn right, deliver) to guide a postbot around a grid, then press GO and watch their plan run from start to finish. Nothing moves until GO, so a child has to think the whole sequence through first, which is exactly what a program is. Later levels hand out fewer cards than the walk needs, so a repeat card has to be discovered rather than told. No reading-heavy instructions and no typing.
It is free to play, needs no account and runs in the browser on a phone, tablet or laptop. Nothing a child makes is stored on our servers: a shared link carries the work itself.
