Hexo's Mission: kids type real code to guide a robot

November 1, 2026 · version v15

A new game where kids write real code, not blocks. They guide Hexo across meadows, rivers and deserts to collect batteries in 10 levels.

Hexo's battery is running low, and full batteries are scattered across the map. In Hexo's Mission, kids help him by typing real code, just like real programmers. No blocks this time.

Three commands to start

The first levels need only step 10, turn left and turn right. Later kids learn:

turn_to battery1: Hexo works out the angle by himself
step distance_to battery1: a function that returns a number
repeat 3 with indented commands: the first loop
for b in batteries: a loop over a list, almost the same as in Python
say "Yay!": because finishing a mission deserves a cheer

Made for learning

Mistakes get friendly messages with the line number, such as "Did you mean step?". The line that is running lights up, a ruler shows the distance from Hexo to the mouse, and a dashed trail shows where he has been. Hexo cannot swim, so the river can only be crossed on the bridge. A sensor stops him just before rocks and trees, so he never crashes.

The 10 levels go from First steps to For every battery. Great from age 9. Play Hexo's Mission!
