I think Casinos often go to great lengths to maintain their reputation and ensure that their games are fair and transparent. If a casino is found to be using deceptive tactics, it could lead to negative publicity, legal action, and damage to their overall business. Therefore, it is generally safe to assume that most casinos do not use deceptive tickets. However, it is important to note that there could be some casinos that may engage in questionable practices, and players should always exercise caution when playing at any casino.
