Ice Bowling

I felt like making something winter themed and working on my (limited) redstone skills so I built this minigame (it isn't much in terms of design but it's quite fun nonetheless).

Rules:
- Each player starts with five different items (if they are the same the game won't work as well)
- Your goal is to throw them past moving pistons onto four pressure plates
- Once all four lights above them are lit up you will receive a prize from a dispenser nearby

You can find the activation lever in the staff building and the piston timer settings under the ice (marked with a sign) if you want to change the game difficulty.

Have fun!

I have just rebuilt the game and much of the redstone circuitry been compacted (see image). I will get a new world save uploaded when I get it off the server I built it on.
