For a $10 app, you want it to be reliable. Unfortunately, far too frequently, the game will crash. Kick you right out in the middle of a turn and take you back to the homepage with a “server lost” type message. Then either your game won’t show back up. Or the play online option will be greyed out. Even shutting the app down and relaunching it doesn’t help.
I have several complex game apps on my phone (Everdell, Lords of Waterdeep, Catan, Splendor, etc). This is the only app that crashes at all. And it happens, like I said, 10+ times per day. Far too frequently for the cost.
The game itself is very well done. The auto button for obvious moves saves time (I always double check the work before I save, but it’s always right where Iwould play the cubes). And it has succeeded in even giving me a better understand of the game as a whole. Great game. Great app. All ruined by poor tech.
