I'm just curious. Don't know if a thread like this has been created in some time but I am excited to see what people say.
Sincerely I think anyone can figure it out on their own. Gambling isn't that much of a complex thing to understand. You can check out the sites you which to play a few times and understand the idea on how to play using their demo modes. The only thing I could think of having some terms is sport betting. In sport betting there are certain terms you need to know but still if you are someone who understands how to navigate the internet you will be able to find it easy to place the bets even in your first trial.
The complexity of gambling is something it resources can not be compiled in a single file since gambling is evolving and every gambling platform having it own TOS and offers.
As for the easy navigation on gambling considering toddler gamblers, that can not be possible and moreover in sports bets, every gamblers have to discover it own strategies which the gambling companies can not determine for players.
As for a learning processed toddler gamblers, if you are to be specific of what kind of game to play with no real betting of money and focuses of building ones knowledge on gambling, then should be the demo which will detail you of how the games could be played.
