After noticing the difficulty of finding adult games suitable for mobile devices we started Mopoga.com. Having 15+ years of experience in game and web development we attempt to only display games that work without problems in mobile browers. Most games are slighly modified by us to make sure they are playable on all devices, including iOS and Android.
If you do find issues with any of the games we'd be grateful if you'd contact us, describing the issue and the device and browser used.
If you're a developer of adult HTML games we'd love to hear from you. We'd also be happy to give some advice on how to get your game to display properly on all devices, usually it just takes a few changes to CSS and embed methods of graphics and video.
