A fun chess exercise. Can actually be quite challenging! Few things preventing me from giving this app 5 stars: The ads are very aggressive! (they stop music, are loud/obnoxious and unskippable), you cannot see the opponents captured pieces, lack of features such as diff models and boards and there's no online multiplayer support. Would be cool to have a "good" chess mode and puzzles to solve. If you make the ads muted by default 5 stars and if you add more features I'll purchase the app.
