I have tried the demo mode but haven't experienced such big wins yet and as far as I know the demo mode works in the same way as we bet the real money and the only difference is fake credits and no difference in the outcomes. Correct me if I am wrong.
How often you try demo mode and how long you play in 1 session? If it is just small size of sample, it is reasonable if you have not experienced big wins with it. There is a specific thread about this demo mode but I forget the title, maybe you can search it and see what most people think about demo mode of slot games.
To get maxwin or bigwin you have to play many times. If you're lucky, it won't take long to win 1000x the bet. But if you have bad luck, it may take longer. Even though I got Maxwin in demo mode, the sensation was less exciting because we couldn't withdraw the money
Yes, the key is the same in my opinion, which is luck in both demo mode and original mode, but in demo mode we are more free in the use of coins, so that no matter how long you play, the coins you have will not run out and you can get big wins or max wins in many rounds that you have to try.
I agree with you that it does feel unpleasant and the sensation is empty, and I think when playing gambling with demo mode the pleasure that should be obtained when winning but instead it is empty and does not feel anything about the pleasure that we expect from gambling in general using real money. I think even though this is the same as playing normally, but indeed the things we get when playing using demo mode and using real money to do gambling are much different even though the implementation or activity is the same.
Yes, maybe the demo mode was created for promotion from the slot machine provider, but from the demo mode we can also learn to make tricks or strategies, we can freely use it to try and find a good strategy for playing slots. Even though there is no definite formula for playing slots, there is no harm in creating a playing strategy
Of course there is no thrilling sensation if we play in demo mode, because even if we get maxwin the money cannot be withdrawn. Actually, what makes gambling interesting is not because of the games in it but because of the money in the game
