Do you want to be old, yet still gamble diamonds in an exciting game? Well, I give you: MINECRAFT BINGO!
Minecraft bingo would be played like normal bingo, using dispensers as random selectors for bingo pieces! Because there are so many placeable blocks in minecraft, you can use those as numbers. You lay them out in a 5x5 square, and that's your board!
For the random dispensing, you need to put one dispenser with a few random items that are all different. We will call this dispenser x. You then have 9 other dispensers, all with different blocks. (Can be same as first dispenser.) You label these dispensers with signs from items from x. You then use the dispenser that x chooses, and the item that comes out will be the bingo piece! Remove the block on your board if it matches the one that the dispenser dropped. Now you can play bingo normally!
(Note, might take a long time to set up. Only useful on SMP, unless you want to play with your piggy friends. )
