where sell casual games?

i am making casual game. it is some kind of mix of puzzles, adventure and mostly hidden object game.
Because we are making progress and our game strating looks to sellable we are considering how to sell it.
There are two ways - the first is to make our own web portal, gameplay videos, demo version and then pay for some advertisement (for example on facebook, or google adsense).
the second way, which i find much more useful is sell it through another portals. for example bigfishgames.
Which sites can you recommend for selling this kind of game? I want to know which publisher are worth to try. has anyone some experiences?
thanks much for any help

I haven’t had any experience with them yet but you could check out steam. You just give them a demo of your game and they will take a look and let you know how much they will sell your game for and will advertise it for you. I think they take like 20% or something like that.

EA’s origin platform may be similar too

If you have a good game, you may wish to apply to all the games sellers out there and wait for the best deal.

my game has not requirements to be accepted on large portals like steam, iwin etc… the main problem is that gameplay will be only about 1 hour…
so I am looking for some marketplace - similar as turbosquid for 3d models. where everyone can buy and sell games
