Simon Tatham's Portable Puzzle Collection

Simon Tatham's Portable Puzzle Collection is a collection of multi-platform single-player puzzle games written mostly by Simon Tatham and licensed under the Expat license. Portions of the collection are by Richard Boulton, James Harvey, Mike Pinna, Jonas Kölker, Dariusz Olszewski, Michael Schierl, Lambros Lambrou, Bernd Schmidt, Steffen Bauer, Lennard Sprong and Rogier Goossens.

It is built on top of a special environment, which makes it easy to make new games, like 3D Maze by Edward Macnaghten, and port them to new platforms by creating new front-ends. The games have been ported to Java with NestedVM and to JavaScript with asm.js, so they are available as web games on the collection's homepage. They are also available on Android and iThings.
