We can't get the complete satisfaction of an offline game while playing it online for games like slots, dice,roulette,etc but the outcome of the online games are somewhat resembles the offline real casinos.Making limited slots will decrease the earning opportunities for the gambling sites so I doubt they would but in future we may have slots like you are looking for but certain amount as minimum bet.
It doesn't matter if a person like to gamble offline (Physical casino) or online casino to get satisfied. Each person have their own likes and dislikes. In your case, you like to gamble online and my guess is you can play any games that an online casinos have and you can also gamble any time you want.
