The answer to this question is play anything that is allowed or offered. The rules are the same and the odds are the same. The best games like dice, Blackjack, Baccarat or Roulette are also the best on a no deposit site. There is no difference between this type of casino site and a regular one in gaming. Playing them is the same and so is the betting. Some of the table games are the best as the house odds are the lowest The odds are the same for regular sites and these sites so these games are the ones that should be played.
The one caveat in this discussion is some sites will limit the games that can be played with a no deposit credit. So in this case, the player is stuck with what is allowed to be played. These may not be the best games on the site too. One set of games that seems to be allowed most of the time is some version of a slot game. the smarter sites are removing all of these restrictions. The older sites are having a problem ridding themselves of these obsolete rules.
Some of the progressive slots are worth giving a few spins in hopes of catching lightening in a bottle. When a site allows these games with the free credit, then a few spins is worth the risk. It only takes one lucky spin to make it happen for the gambler in a progressive game. The other obvious game to try with this money is baccarat or blackjack as these games have the lowest house edge. Most sites offer both games and if they are both allowed, give both a try. Roulette is not the best game to play for odds, but the game has a mystic about it and players love to play the game in live casinos. In an online site the rules are the same, but the playing ambiance is lost online. For this reason, most players stay away from this game online.
The no deposit sites are not really different in any way from other sites as far as the games are concerned. The player has no concern to consider if this is the site you are playing one.
So the word is give the games you like a try and do not worry about the playing rules. The only rule that can stop this are site restrictions that the site has about how no deposit credits can be wagered.
