A coding game for kids aged 6 to 12. Snap blocks together, send out a squad of robots, and fix the bugs when things go splash.

Counting squares only works for one robot. When three robots start on different streets, kids have to write a rule that works for all of them. That is what programmers do every day.
Drive, turn, build a bridge, repeat until, if, if / else. Drag them in, or tap to add.
Coloured dots show which block each robot is running, so kids can see their code come alive.
The Step button runs one block at a time and shows every yes / no answer a robot gets.

Some levels start with a broken program. Robot 1 is fine, Robot 2 sinks. Kids step through the code, find the case it doesn't handle, and fix it.
Most coding games only teach writing code. Reading and fixing it is the part that makes real programmers.

It runs in the browser, so a class can start with a link. On phones the map and code have their own tabs, with a live mini map above the program.
