Solumns

Solumns is an evil game, superficially similar to the classic Sega game "Columns".

It is evil because it gives the player annoyingly poor combinations of colours.

This may lead to swearing

Solumns should run on all popular operating systems, because it is written in Racket.
Solumns is now in beta development stage. It works perfectly for many people, but you might still find a lump.
