I don't feel any excitement dealing with demo mode because we can be so careless placing our bets and I also think that we are less observative that's why I don't really use this feature.
Compare if you place real money and bet according to what you like to play for sure the excitement is their and you became more careful dealing certain situations happening especially that you don't want to lose huge and somehow want to end your game with profits to get or withdraw.
But just enjoy all of these guys and choose what makes you comfortable since somehow each of us have different preferences.
Demos are only for learning the gameplay. well, this feature won't have a significant impact except as a knowladge base for the slots game, that's why you are not excited to try the demo feature. Real games, which require real money, will have an emotional impact. I usually use demo to try out new games on slot. This feature help me to understand how many symbols are needed to get free spins and what the reward is for connecting the smallest number of symbols from normal spins.
Yeah its for familiarization and usually people don't enjoy especially that they didn't get anything with it. That's why people choose to go on real play because they want to take a chance to win huge especially if they lucky enough to pull big wins on the casino games they are currently playing.
Usually I use demo to when there's new games introduce by the casino. But didn't last long especially I don't want to waste my time there.
Somehow this feature is indeed helpful since it can make us minimize our losses especially if we want to try those new things casino offer to us.
