Iwin is a game developer, as well as a game portal. So they make games, and they sell games made by themselves and by other developer. They are the makers of the Jewel Quest series (match3-games), they made Family Feud series, Jojo's Fashion show and many other.
Their game portal site has a lot of activities - with something called Hotel Iwin - what is a "social casual Game Virtual World". You earn "opals" from buying and playing games from their portal, and these opals can be used to get stuff for your hotel room at Hotel Iwin.
And here are also different online games.

Games are quite cheap, depending on your membership status. As a member of either Club Iwin or All Access, you get cheaper games(USD6.99), access to super-low offers (as low as USD 3.49) if you buy games, or unlimited play (renting) plus a monthly bonus game as long as you are a member. As a non-member you pay as low as 9.99 up to 19.99 for CE-games.

Some games are free to download and play, but they come with ads.
They have game forums, with customer reviews and game tips.

One thing I didn't like was the fact that their games come with a mandatory game manager. You cannot play your games without it. Part of the reason may be the "opals" you earn simply by playing your games, this Game Manager records how long you play a game, and award you accordingly. But inherent in this is that Iwin can monitor how long you spend playing a game.
Another factor against them is that my AV (two different ones) really didn't like some of the files in their Game Manager and believed them to be Trojans. I ok-d the suspicous files, but after an update to my AV, they were back to being suspicous again.

Either this company has a lousy practice of talking to AV-programs, or some of their GM-files are actually that invasive, and I suspect that this is partly correct seeing as the GM has the capability of monitoring and reporting your gaming habit.

I do not think this is done with malicious intent, but one need to consider if one wants a game portal to have this information, and what exactly they do with it.

If you are VERY good at reading everything that comes in fine print, it's an okay game site, I guess.
Download games only. Cheap games, but when you buy you are automatically signed up for a monthly membership - unless you are sharp enough to see the tiny tick in the tiny box saying Big Fish Game Club Trial. And they don't really spell it out what the Game Club trial actually means...
If you do not remove the tick, or remember to "unsubscribe" by the end of the month then you are a member of their club and must buy a game a month. At least they charge your credit card/Pay Pal account for 1 game each month. If you are a member, buying 6 games in a calendar month will give you 1 free game the next month.
Non-members can still buy games, but they pay more.
So-so Customer service - instead of helping you all the way until you can play the game, they are quick to give up, blame it on your obsolete graphics card, and offer a free game coupon instead. So that you can download another game that might not work.
