Not necessary that it must all be about slot education alone, there are other aspect in which we may have to upgrade ourselves from and learn how we could get informed on the basic requirements for using them, slot education from its own aspect is what can help as many as possible in discovering about the minimum expectation one should have with slot games including the way to play it.
There is no minimum expectation with slots... slots can give a lot, but they can take a lot more. So there is only one education about slots, if you want to play slots be prepared to lose everything. If you're not ready for that, then don't even play them. As I said, slots can give a lot, but they can take a lot more....
10-20-30 dead spins, bonuses with under x5 after more than a hundred spins are nothing unusual... and all providers and all their slots can give you the same experience if you play them long enough.
