This is a JavaScript implementation of Myrmex, a solitaire game for the Decktet card system. The Decktet was created by P.D. Magnus and released under a CC license. Myrmex was created by Greg James; all of his variants are supported.

The JavaScript implementation is partly based on an implementation of Adaman by Felbrigg Herriot, who released it under a Creative Commons Attribution NonCommercial ShareAlike 3.0 License. Myrmex can be played in any browser (desktop or mobile), and will work offline. A game can also be saved for later.


Myrmex is a Decktet version of Spider, which I wanted to be able to play even when there isn't room to spread out my double Decktet deck.


In certain situations, a legal move will appear to fail. (It is actually being undone, probably due to a bug in one of the drag-and-drop libraries used.) Workaround: you can un-undo it using the Undo button.

Undo only undoes one move; undoing again will re-do. Undo will not undo a deal.
