User reviews

Klasse Schachapp

Macht Spaß und ist abwechslungsreich.
Genau richtig für eine schnelle Partie zwischendurch.

Basic and ok

Limited features. Like the book availablility. However, I beat it with easy, set at 2000. No way it was playing at that strength.

Email games does not work. ????

Simple yet powerful

I really like the UI as it is 2D. The games are also adjustable for difficulty level. Really love this.

Response from developer

I"m glad you like that. I think the adjustable levels for the variants like crazyhouse, atomic and losers as well as chess is what makes it fun There is an update out now with flip as the main feature in review mode.

Fun app

Feels great to go up against another chess engine. I am really enjoying the app.

Game works and is fun

I played the iPad version of this, on my iPad. The game worked very well. I enjoyed it. It would be nice if the game would tell me when my king is in check. I thought that the game had frozen. In fact, my king was in check. It is a fun and worthwhile game on the iPad.

Suggestions to the Author:

1. Please create a “Baby” level. “Easy” is too hard! Your game is relentless. It covers every piece that it advances.

2. When an enemy piece moves, please make this happen slowly. Your enemy pieces move so quickly that I can’t tell what happened. This is especially irksome when I think the enemy captured one of my pieces.

3. Please tell me when I’m in “check”.

4. A clearer statement of “check mate” would be helpful.

Thank you.
