I use it on my iPad, but it is available on the iPhone as well. One note - Specifically A House in the Rift needs to be uncompressed then moved manually into the Games folder in Spark. For some reason their download doesn’t import properly. I have never had an issue with this game, though. But if any users run into that issue, have them uncompress it in the Files app and move it to the Games folder within the Spark folder. When they reload Spark, the game will show in the list.
