People post up made games for free- simple as that.
If you have the game it is different than not having the game. The game is not free and you can not go to a site and play there game, you need your game to play online against other people
Asking people to donate, and advertising are really the only ways a free game developer can earn money without being qualified as a "Shareware game developer".
If you want to find an online site for a free puzzle game you can try Gamehouse they offer a free game everyday. Just click on the free game for the day and then you can see more games that are for free, Enjoy!
