I know you want to promote poker but point one is wrong:

"1.) No direct buy-in: Every poker contest here is either completely free or requires a small deposit and wager (1x-2x)."

You can't talk about free when deposits and wager is mandatory. Also, prices won in 99% of cases must ALSO be wagered at least one time before they can be withdrawn, which makes it even harder to be "profitable". At betfury for example, when you win in the poker tournament you have to wager 1x, that's true. But you can't bet it on sports and if you wager it on originals for example (which only counts 20%) you basically have to wager the whole amount 5x. Hard to stay in good profit that way.

The "fun" aspect is a whole different story.
