Casinos often add games to their software. Players are ready to jump on board with them to see what is new. When the games first launch they normally do pay out a bit but it is better to play the games after they have been out for a bit. As in all casinos they games payout once a percentage of bets have went into the machine. So as you may hit a bit when they first are released your bigger wins come after they have been played more. Just have more caution on bigger bets on new games and wait awhile to increase those bets for the best out come on the games. Older games do sometimes get exhausted in paying out as players move on to different games, then old ones get played less. So your odds of winning on very old games decreases as well.
