I want to play a long session to test a strategy, but I don't want to sit there clicking the mouse every single second. Does this game have advanced auto-play features where I can set loss limits or a specific number of rounds?

Yes, the Plinko Casino Game generally comes with extensive betting options. You can use "Auto Betting" to set the number of balls to drop automatically, and you can even use hotkeys for instant betting to speed up the gameplay. It allows you to automate the process while you watch the distribution of outcomes.
