Infinity Blade is an iOS game available for iPhone, iPad, and iPod Touch. It is typically seen as a send-up of the classic game Punch-Out!! mashed up with roleplaying game conventions such as experience points and character-modifying equipment. Its defining trait is that it relies upon new game+ to advance your character (actually your character's family/bloodline) and the story. J. Nicholas Geist over at Kill Screen has written a review to match the game.

Canvas Rider is an addictive game where you ride a bike on thousands of tracks drawn by other players. It's written only in JavaScript & HTML5, using the most of the new <canvas> element.

Deepleap is a word game. Make words and fight against the clock. (via). There's another hit from 2000 about deepleap.org, but it has nothing to do with the word game.

SmokymokeyS has been around for some time, but I've never seen it mentioned here. There's some great design and imagery to be found there, and they've been working on a Javascript RPG called Triglav, which although they say it's unfinished, seems pretty functional and very cool.
