I always see players advertising casino's and thought that it might be a profitable trade, but i have no idea how to do it without using hundreds of droppers, dispensers and hoppers, any ideas?
All you need is one dispenser, fill it up with three main blocks of your choosing, each block means something, for example if you hit the button, lever, etc.. and it shoots out a redstone it would mean they win (You give them x2 of what they gave you), if it shoots obsidian then it means you win (So you keep the items they bet) , and if it shoots out stone then it means hit the lever/button again. Make sure you clearly let them know what each block means that comes out of the dispenser. It's hard to get a good casino going because there are people who will cheat and fill their dispensers with winning blocks making it impossible for someone else to win. So at first it will be a challenge to gain a trusted reputation. Those are pretty much the basics of a casino, you can add your own personal little quirks such as deals etc.. Good luck with your casino.
