Original games

Play a round.

These two games were written for this site. Commercial Atari cartridges are not open source, so they are not here. The Stella emulator is GPL-2.0; it plays ROMs you already own, and those ROMs are not part of Stella.

A bar at the bottom catches falling lesson labels, or keeps a ball in play.

Score 0 · Lives 3

Catch a label. The line under the board is the lesson.

Arrow keys or A and D move the bar. Stella’s license: GPL-2.0, stella-emu/stella.
