Three robots on flooded streets, with a block program on the right showing repeat until on animal, if water ahead, build bridge, drive.
How it works

Every robot runs the same program

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.

1 · BuildSnap blocks together

Drive, turn, build a bridge, repeat until, if, if / else. Drag them in, or tap to add.

2 · RunWatch the squad go

Coloured dots show which block each robot is running, so kids can see their code come alive.

3 · DebugStep through and fix

The Step button runs one block at a time and shows every yes / no answer a robot gets.

A Bug Hunt level: Professor Glitch's program with yes and no badges on each condition, and a step log under the map.

Bug Hunts with Professor Glitch

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.

Works on Chromebooks, tablets and phones

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.
