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 an image reassembly game similar to a jigsaw puzzle, but with greater variety in how the image is cut up. You can use straight lines ("razor cuts"), traditional jigsaw cuts, and also simpler single, double or triple curves. A customizable "random" option allows you to mix these kinds of cuts in a single puzzle.
Puzzles can range in size from 8 to 500 pieces on iPads (8 to 192 pieces on phones).
Although you can request to preserve the lines between pieces as you solve a puzzle, the usual behavior is for the pieces to fuse completely, allowing the original image to emerge gradually.
The app comes with samples to get you started and also features an integration with the photo sharing sites Unsplash, Pexels, and Pixabay, allowing you to acquire new photos and make them into puzzles. You can also import images from other sources, such as your photo library.
You solve the puzzles in a flexible, zoomable pane that also gives you adjustable background color and 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.
