user3405: I am looking for a tactic training software for Windows/Linux/Symbian. I think that I know all tactics by now, and I want to train myself in using them. I do not want tactical software that separate their lessons, such as Chessimo. I want them to have an Elo system of sorts that gives harder puzzles for an higher Elo, and easier puzzles for lower Elo.
The only examples that I can think of are Tactic Trainer for Android and the chess.com Tactics. I am quite sure that there is a similar thing for Windows. Also please not online, I'm looking for software. Price is not a issue, at least 'til $50.
Thank you people in advance. 

user9684: Chess Hero is a free program.  It does not select based on strength of puzzle but random choice, but I think it is the best offline trainer.
Here is a list of pdf files which are separated by difficulty.
If you want to invest the time, you could order a pgn/fen file from easiest to hardest.
