Premium Plinko
Chat Plinko that Dual IRL runs for your account: viewers type the drop command or use the drop emote, Dual IRL picks where every ball lands and keeps the scores, and your Plinko shows what happens.
Everything the Free Plinko lets you set is here: the commands and the drop emote, the rows and difficulty, the drop limits, the chat color of the ball, starting hidden and the look. Set it below and save the game settings, then copy the address and add it to OBS as a browser source. It uses the account you are signed in to, so there is no channel to name and no address to paste.
