There's something faintly amusing about a title collecting retro table top games having an HD tag, but Flick Champions HD (App Store, iPhone/iPad, £1.99, Nawia Games) boasts just that. In crystal-clear high definition, it's a good value collection of eight finger-flicking sports – basketball, football, hockey, tennis, archery, baseball, bowling and American football. Only the first four are available from the off, with the others unlocked as you gain experience. It's simple fun, with static, block-headed players scoring goals with a swipe, or shooting hoops with carefully judged digit precision, but it's perfect for touchscreen devices. It's also a rare chance for some multiplayer fun while sitting at opposite ends of an iPad. A real opponent, actually in the room with you? It doesn't get more HD than that.
