Madgick Cap

Mathcat

Higher or Lower, at least, lets you go above the 5000 blue stone cap for Madgick games.

Need site currency? Playing with my hundreds of companions here can earn you a decent amount of both blue stones and reactor stones. Companions may be played with once per hour (total, not per user). If nothing shows up, check back later.

Still on AO3 here - Forest of Mirrors, Dragon Cave, MagiStream, Jelle's Marble Runs, and original fiction.
