Not just the newbies but also to everyone who plays online casino. And it also advisable to look at the guidelines of the the game as iy may change with time. This will help you not to default as there are penalties to any defaulter of the rules.
What the OP have said is not merely for the newbies only but for all the gamblers here in this forum because even the old gamblers still make some mistake and likely skip the ToS/T&C and even FAQ because of that mindset that maybe this platform is not that different to the other one when in-fact there's a huge chance that the other platform have their own set of rules that is really different to the other one.
It's not just costly gambling mistakes for the newbies but for also the regular gamblers, and this thread that is made by the OP shall be a reminder to all of us.
