This is a recreation of the solitaire Sigmar's Garden from the Zachtronics video game Opus Magnum. It features the three variants of the solitaire featured in the game (Original, Quintessence, House Colvan), as well as two that were created for mods of the game. (Production, Saverio)

Most of the code was by me, with contributions from Adamanti (who added the speedrun timers and per-variant stats) and Greenfield (who added the Saverio variant)
