which has better odds: physical casinos or online casinos?
Truly the online gambling casinos have more better odds, but we should not treat things with gambling like that, because the higher these odds the tougher it becomes to win, because the risk is also high together with the odd for those that mostly sort out for big odds in gambling.
the answer is online casinos. the reason for this is they have a lower cost for starting and operating the casino if it is online so there is not much needed to break even or get profit but physical casinos has a lot of costs just from the building, working employees, electricity or other maintenance needed.
Don't conclude yet, because there are better odds also in playing physical casinos, it's all about the risk and the kind of game involved for which an odd is allocated.
