The strength of the original board game completely carries this app implementation of it. It's a fantastic 2-player abstract game that I will never grow tired of. It's perfect for fans of Tetris, puzzles, or low-stakes economic optimization.

But the app has it's issues (at least on Android). Some of the menus are buggy and don't close properly, and I wish there was a portrait mode option that allowed for your player board to be larger. But the biggest shame is that loading times and animations take a while, and this is designed to be a quick game with snappy back and forth turns. If playing asynchronously and you're waiting on push notifications for your turn, it can take the game longer to boot up, login, load the game, and play the animation for your opponent's turn than it does to take your actual move.

In short, I'd highly recommend the physical board game first, or the more streamlined web-based Board Game Arena version. But if you really like the game, or want to play against the AI or friends online, then this app is serviceable and can be fun.
