## Review summary

Reviewers praise CrazyStone DeepLearning for its strong Go AI and beginner-friendly features, including hint mode and mid-game territory visibility. The app offers flexible play with multiple board sizes and AI-versus-AI options, making it good for learning and passing time. However, the free version is heavily ad-supported with long, unskippable ads that disrupt play, and landscape rotation support is lacking. Overall, it’s among the best Go apps, but ad experience and lack of landscape support detract.

### Pros

- Strong Go AI across multiple difficulty levels; widely praised as among the best Go apps.
- Excellent for beginners: helpful hint mode and mid-game territory display to learn strategy.
- Flexible play options: multiple board sizes and ability to have AI vs AI or human play.
- Helpful for focus and learning: can use to stay focused during waiting times and teach others the game.

### Cons

- Intrusive, long ads in the free version; unskippable and after nearly every game.
- Ads disrupt gameplay; sometimes the close button is hard to reach or outside screen.
- Free version heavily ad-supported; many reviewers would pay to remove ads.
- Lack of landscape rotation support for iPad/iPhone; no landscape mode currently.
