Medium strength, highly inefficient engine, good UI. If you could replace Chess engine with Stockfish I would pay again for this app! I love Stockfish which is twice as deadly and many times faster to move, but I hate the complicated DroidFish UI in that app. I love this UI in this app but engine is slow and relatively weak. Drains battery with long move times on level 11 and 12.
I first tried Shredder Chess at 4 times this price, but I had several interface and usability problems and decided to give it back: on the small, low-res screen of my phone the menu button was not present AT ALL, i.e. I couldn't change any of the options. Secondly, the captured pieces were tiny, and the black ones were virtually invisible against a dark grey background. Thirdly, you had to drag the pieces from their current place to the new one. AI Factory's Chess works just fine regarding all the above areas, all the buttons are easy to see, so are the captured pieces, and instead of dragging the pieces, you just tap a piece and then tap its desired location, and that's it. I'm giving Chess 4 stars because, on the one hand, I don't know it well enough to pass a final verdict, secondly because there was one feature in Shredder I might miss here: 1,000 chess puzzles to solve. But for this price Chess is awesome!
Natural-feeling opponent, fun to play against. Comfortable low-strain chessboard options, too. No big AI quirks, so I find it quite a natural opponent, even if it IS inhumanly infallible...and inexorable...and ruthless. One odd thing in a game I recently played: the AI completed a queen-side castling (the first time I've seen it do one), but it did it by crossing a THREATENED square. [I didn't record the game, darn it, but the reply below shows that it was probably only the rook that was crossing. At least it's clear that people who know the rules better than I do are keeping an eye on things.]
Solid app; Some frustration with saved games All around a very good app. My one big complaint is how it handles saved games. What I really wish I could do is take a completed game that I played in "pro" mode, then go back and pick up the action part way through, but with hints and the other helps available in "casual" mode available. This would be a great way to learn, but for some reason the app does not allow this (even though it tells you up front that the stats don't count when you're playing from a saved game).
Good points: -The price is great. -App loads fast -Different-looking pieces are nice as are board colors -I often play games on difficulty level 5, which is about where I am and feels right. The computer does feel right, although sometimes its blunders are very questionable. Still, I get a fighting chance. Points for improvement: -The biggest one I can think of is there should be an option to set up a custom board position and even save the position. It would be great as an endgame practice tool as well as trying out custom chess problems. In fact, maybe the app could even have some custom problems built-in for a future update. -When there is insufficient material to win, the game should automatically draw. For instance, I've had a bishop/king vs. king and the computer kept playing until after about 15 random moves it finally agreed to the draw. The only time it auto draws is if it's the two kings only. -Minor, but In the chess notation, when castling happens, could it be changed to the standard O-O and O-O-O? -Minor, but how about an option to input manual RGB colors for the board's dark/light colors? Those are my thoughts.
Can't seem to get more advanced help option to work, otherwise good app. P.S. would love to see an english language version of Shogi! Edit: Thank you for your help and support. It's too bad about the Shogi game, but I can understand that the priority is with maintaining your existing game apps. Again, thank you!
