Other casino can provide the same game but it will boil down to the bonuses and services that they offer. Indeed demo mode is less rig but like what @jetcash said, their main function might be to show what is inside the bonus feature of the games. In demo mode, we can be able to bet high, no wonder why the winnings that we got there are also huge. If we have the ability to do the same in a real game, we can also win the same amount if we get lucky.
It is a good way to see the demo mode of the game, in particular I have always said something, when slots are played a lot, there are many promotions and bonuses are always or almost always associated with slots, that is, if we take a bonus, we generally know the difficulty that there is in the bonuses, because with the demo mode in the slots things change, because if there is a demanding wager, for example about 5x or about 10x which is an exaggeration for me In that case, I could practice in demo mode to see if that can be achieved, and it's much better to do it that way than in real mode, well, it's something I've always thought about, because we always see promotions on some sites that give the bonus or that there is a bonus that can be taken but with very high demands, then the demo mode is the friendliest, and you can practice a lot without touching real money.
This is a way to take advantage, and well it is not bad, whenever I have seen some promotions on sites, the bonuses are given to them in pragmatic slot machines and they have to make a certain number of wagering to be able to unlock the bonus well and make it withdrawable, some of us Players don't think it's fair, some of them get stressed because they start to play and because they see that their balance is going very fast, because they play with rage, with rage, eager to get their money back or at least the one that was deposited because they lose everything at once. time, but casinos always give options, and we as intelligent players must study and take advantage of those options, if they give the demo mode, then let's take advantage of the demo mode, if in the demo mode we do everything 5x or 10x we realize the way what we bet, in how long the objective was achieved, or not achieved, how could it be done, how much can be bet to get to that quickly, these things are the ones that have to be evaluated, but obviously they go in another direction, I understand that when there is money risked and dammed in some way one feels the need to unlock it and recover it, it is up to the person if they want to do it or not.
