the wrong game, yes.. goocubelets (the original) has been given away free before, and as such can't be given away on this site (that's why you couldn't find it on the list). I'm afraid i cannot mark it received in this case... if you send me a key for The Algoorithm, i can then mark it received, but otherwise I cannot (because then my account would have an unredeemed win on it, which is bad). I'll give you a week to sort things out before that though, just in case. (don't want to give your account a black mark without you having a chance to fix it)

Also, the key you sent i haven't used, and won't hand off to anyone else, so you're free to give it to a friend or gift the key to a forum thread or trade without fear. ^_^
