Gamblers are more interested in seeing good and interesting games on casinos.
When there are good games with better odds, gamblers will have the interest to keep playing even though there bankroll is diminishing.
We need to keep seeing casinos updating there games everything with a better odds to select from.
When talking about casino games, everything is almost the same, there are no significant differences because the game is from a service provider as well as RTP, so interesting games are not the player's main target, unless the casino has in-house games which don't exist in any casino, maybe players will be very interested. Meanwhile, for bookmakers, punters will take into account the difference in odds, even if it's only a little, which is why at big sporting events, bookies sometimes provide promotions such as odds boosts. So that often giving bonuses even though in a format that is no different from other competitors will be in great demand by gamblers.
