Chess game is tablet friendly, layout is exactly the same on 16:9 rectangular tablets. However, on 4:3 square tablets, the chess board fills the entire screen in portrait mode as pictured, but scales down to half-size in landscape and snaps to bottom-right corner, I guess to accommodate for one-handed playing. Why not add this option to portrait mode! Overall, love the game and battery-saving theme!
