Okay so what i want to know is how to change the drop depth and not the coins, i want the depth of the game to change but not the coins, how do i do that, what i would like is a video of you showing to change the drop depth to any number just to know how to change it

Sorry for being quite dumb but can you please create another video on how to change the depth because the previous ones have been deleted and I honestly don't understand the instructions
