dicepro: IMO, perfect information isn't a necessity for a game to work well on a turn-based site. The various boat games, Logic and Frog Finder are examples of games without perfect information that work well. Also, games involving dice don't have perfect information - but they work well.

What, IMO, is a necessity is that the history of the game isn't important. That is, all you need to decide on the best move is the current situation on the board, regardless of how it has been archieved. This is why, IMO, most card games are unsuitable for turn-based sites. (And that's why I don't like to play Dark chess or Espionage on a turn based site).

AbigailII: I think you are wrong ... do not try to play with guys from Professional Dominoes Association without "historical" knowledge of the situation on the board ... Logik is a bad example since you do not actually play agains the opponent, and you do not have to remember anything he/she did and why ... you play against yourself, it's like golf, darts, bowling etc ...
Chess ia a game of perfect information, cards are not ... you have to assume some plays based on your calculations ... this is why cards cannot be played well on turn-base sites without (sometimes) complex notes ... card game I gave you a link to, is a rare card game with 100 percent perfect information, and you do not have to assume anything beside the consequences of your move ...
all your "pieces" and opponent's are known ... isn't it a board game using plastic cards instead of wooden pieces ?
And you do not like games, like dark Chess, for the reason you consider not important, contradictiong yourself ...

AbigailII: What is important is that games like Dominoes, Various cards games etc... if they are wanted & will get played, should be looked in to
