Have you even wanted to play Bowling in Minecraft? I introduce you to my map, a functional bowling map! I have currently only built the main part of the bowling, I may build the rest of the parts sooner or so.
If you are interested to see how it looks like and how it works, I will give four samples.
A functional board showing the pins you have hit.
How it works on the back.
A reset button in case if you want to throw again.
Here's the view. If you don't know how to throw, you just need to drop the item, as the block below the back carpet is blue ice. Also you dont have to throw one spot every one bowling ball, I made it so that it knocks out other pins too, but just most of the chances.
Once you have downloaded, just tap/click the file and import it to your Minecraft.
