Where does the random number come from?
How is the winner determined?
Is the operator a "flight risk"?
Does the game give you "deja vu"?
Bitcoin gambling can be fun but like all gambling it also has risks. Try to be aware of where those risks are. Pretty much any game can be played by the owner. By thinking about the operator playing you can see the areas where cheating can occur. Each area that can be cheated adds to the total risk. Choose what's comfortable to you.
Play safe!
I agree with all of this. This is why I'm creating a site where instead of having some unknown robot run these games, you have the community members running the games, or hosts. This way, you can see the terms of the game clearly, whether or not the host will be actually making money from the game and whether or not they appear legitimate. If anyone is caught cheating or tries to run off with the BTC, the site insures the winnings. So if the host doesn't pay, WE will honor the bet. This is kinda cool though, because if you want to try and make some money running a poker game you can do that, without having to pay anyone for the server space or anything else. You can also organize tournaments so that you can actually have pretty decent sized pots.
This is a personal project for me that I'm hoping will help lend legitimacy to the BitCoin merchant network. I realize that table games and board games don't go a long way to establish this, however it is really more about the idea of a community inspired by my love of networking. If anyone has ideas or anything, please let me know. If you wanna see what I've got up so far, check bitbetter.org.
