These games were designed for a 1920 x 1080 pixel screen. They've also been successfully tested on 1280 x 1024, 1280 x 960, 1152 x 864, 1024 x 768, and 800 x 600 pixel screens, although you usually can't see the entire game board at once on the smaller resolutions - you have to scroll.
These games also work on 1360 x 768, 1680 x 1050, 1280 x 800, 1280 x 768, and 1280 x 720 pixel screens, but the images are distorted - squares appear as rectangles.
