The unigame family of games is being developed in open source at https://github.com/joshuaauerbachwatson/unigame and several related repositories. It is an evolution of an older project called AnyCards but has taken on some new directions. See the open source README for more details. There was once an AnyCards beta but it has expired and there are no betas yet for the new work..
Razor Puzzle is for jigsaw fans who would like more variety in how their puzzles are cut into pieces. The cuts can be straight lines, traditional jigsaw cuts, and/or also simpler single, double or triple curves. A "random" option allows you to mix these kinds of cuts in a single puzzle and to customize the mix of choices. Puzzles can range in size from 8 to 320 pieces.
Although you can preserve the lines between pieces as you solve a puzzle, you can also have the pieces fuse completely so that the original image emerges.
The app comes with some starter images and some puzzles made from those images, illustrating the different kinds of cuts. You can use inter-app sharing to acquire more images from any app that might provide images, such as Photos, Files, web browsers, or the apps supplied by free photo-sharing sites such as Unsplash, Pexels, and Pixabay . A more direct import capability for images is planned for the 1.3 release.
Razor Puzzle then helps you make puzzles from your images, both the provided ones, and any new ones that you add. You solve the puzzles in a flexible, zoomable pane that also gives you a generous number of scrollable "trays" to hold pieces while you solve.
I retired in 2016 from a long career at IBM Research. For two and half years, I focused on my skills as a serious amateur bassoonist and amused myself writing game apps for iPad and iPhone. During that time, I published two apps in the Apple app store.
Then , in January 2019, I went to work for Nimbella Corporation and abruptly stopped working on apps. I retired from Nimbella in May, 2021, at which time I withdrew the older of my two apps from sale and upgraded my Razor Puzzle app to version 1.1, with support for larger puzzles and several other new features.
My retirement from Nimbella only lasted a few months, though, because Nimbella was purchased by DigitalOcean and I was persuaded to join the larger company for a while to work on the integration. Again, I stopped working on apps.
I retired a third time (from DigitalOcean) at the end of 2022 and once again my mind turns toward apps. I divide this work between the newer unigame (formerly AnyCards) and the more mature Razor Puzzle.
