A waste of money - too few puzzles included.
I like to play WoF when I'm waiting in doctor's offices and the like. Unlike v5 and v6, where you purchase the game once for $4.99, 2005 costs $3.99 per month. I would say I played maybe 10 games of WoF2005 and got a message saying I had played through all the puzzles, and to get more it would cost me airtime charges.
Also, in versions 5 and 6, each puzzle was a separate item, and puzzles were randomized. In 2005, however, the puzzles and bonus rounds are tied together in one game, so they cannot be randomized. This greatly takes away from any replay value 2005 might have had.
$3.99 for 10 or so, non-randomized puzzles, is way too much money. As I said, there's nothing wrong with the game itself, there's just far too little of it for my money.
