[Goozik]

This is probably the best up and coming Skill Gaming site. I would currently rank it only behind King and Worldwinner.

Best of the site - Free games Calender. Every day play a game against the AI. Win 50 cents. Lose nothing.
Worst- The Real $ to game $ conversion isn't exact and confusing at times to figure out how much money you have.

2nd best- Versions of Battleship and Minesweeper
2nd worst- Lack of word games


Other pros to the site:
Lots of Card games.
8 Country's supported.
Mini-Leagues are a nice "round robin" tourney structure alternative
Few games not found on most other sites, Yahtzee, Sodoku, Minesweeper, Battleship,Connect 4, MahJong and Tetris.

Other Cons to the site :
Lack of game genre diversity, only one word game lack of action and sports games.
Small withdraw fee. (usually about a buck) Not so bad, but still annoying.

Pro/Con depending on how you look at it:
Can not tell how many people are playing online atm.
About 30 games total. Mostly Card and Puzzle games.
Top 100 leader board for each game is public.
Can see who is already in the game if you sign up to it.

Final Thoughts
The Free game Calender is awesome with different game each day. Nice to log in and win a bit every day, or lose nothing.
The withdraw fee is small but does affect you over time, so larger withdraws are better here.
Instantly signed up to this site for the battleship alone, it's just great to play a version of that for money.
Been around for many years with solid reputation.
