Create an Interactive Iterated Game
Each game is a self-contained web page, which can be edited with any software that edits HTML. It can be included in your own Web site or VLE or run from a local disk. Once you've pressed the button above, use the "Save As" or "Save Page As" feature on your browser to save your own copy of the game.
