Draw a single stroke, flip tiles from black to white or vice versa, and turn each single line into a solid color each.

Polarium demake for HP 48 graphing calculators, implemented in Octo for SUPER-CHIP.

Instructions on how to load and run this program on your own HP 48 calculator


Chipolarium is a puzzle game with 100 levels, where the goal for each level is to flip black and white tiles so each row is a single color, by drawing a connected stroke through all tiles to flip.


The controls will vary depending on whether you're running in your browser, on an actual HP 48 calculator, or in a general CHIP-8/SUPER-CHIP emulator/interpreter.
