How to enjoy bingo game at Minecraft.

I would like to introduce the bingo game I play with Minecraft.
(I confirmed the operation with version 1.13)

What is a bingo game?

"A game with numbers written in 5 × 5 squares is a game where those who satisfy the condition win.”

In the bingo game being carried out at the party, cards which arranged numbers first are distributed, and the moderator reads random numbers chosen by the bingo machine in turn.

If there is a corresponding number on the card, I will open up a hole.
When holes are arranged vertically, horizontally, diagonally, one line, say "BINGO" and go out. The earliest person is the winner.

Rules of the original bingo game to do at MineCraft

Minecraft's bingo I use "various items" instead of numbers from 1 to 75. Place the item 5x5 in the block frame and mark it with a torch.

(Place 'glass' in the center of the card to indicate that there are holes)

Participants arrange items freely. In actual bingo games, I use numbers from 1 to 75, but the large chest is 54 squares, so I set 54 items as one set.
Prepare a set of items for the number of participants and a set of items to put in the bingo machine.

By arranging the frame and the glass in advance, participants think that it is easy to arrange the items.

It is an item contained in a large chest. It is one for each type. I think it's a good idea to choose items that are easy to distinguish.

Bingo machine description

Have you ever seen Bingo Machine's toys?
There are many balls with numbers written in the sphere of the wire.When the sphere of the wire is rotated, the balls in the mix are mixed, and a single ball comes out randomly.

Briefly, 54 items move in the dropper's loop. Since the dropper expels at random, the more it turns, the more the 54 items are mixed. From there we take out one by one, and advance the bingo game.

How to make a bingo machine

1, item shuffling device

Let's make a device to mix items together. It is a sphere part made of wire of a toy bingo machine.

How to make

① Install a dropper on the third block of the ground. I will place the front of the dropper at the next dropper.

② Place the block which becomes the base of the clock circuit.

③ Install the clock circuit. (Right click on the comparator once)

④ Connect all dropper and clock circuit with redstone dust.

2, Production of item outlet

The hopper needs to be installed under the dropper whose item can be seen. Switch on the clock circuit, please check the appropriate number of items in the dropper. This time there is no problem if it is a dropper on the left and the middle as seen from the front. If there is a problem, please replace the left and right or move the installation location.

How to make

① Set the dispenser, place the hopper behind, and place the hopper on the hopper.(Under the dropper that can see the item)

② Drill two blocks next to the dispenser. Put redstone repeater and redstone powder there. Click on the repeater and set it to the maximum delay.

③ Place the block next to the dispenser and cover it. I will install a stone button in the right block.

④ Place the torch behind the block to which the button is attached. In addition, it is connected to the lower hopper with red stone powder.
Since the signal is sent to the hopper below, it does not inhale regular items. When you push the stone switch, the red stone torch goes off, sucks the item and sends it to the eyedropper.

⑤ When one item enters the hopper above, we want to stop sucking, so install a comparator and connect it to the upper hopper via block and repeater.

⑥ In addition, to prevent power from being transmitted to the hopper below, use the half block as the foundation.

3, item takeout control device

Even in this stage, if you press the button, items pop out one by one. However, since the next item also enters the hopper, I will know the type.

As a countermeasure, we added a mechanism that does not remove from the item shuffling device until the switch is turned on.

First of all, please look at the picture below.

This is the circuit that stores the signal. When the redstone dust is flashing red, the hopper can remove items from the item shuffling device.

When the item is taken out, a signal is output from the comparator next to the hopper and sent to the central Redstone repeater.
Then, the blinking red stone dust will disappear and you will not be able to take it out. It is the moment that the powder is shining.

How to make

① Install the circuit as shown in the photo above.

② Place the torch on the side of the block next to the comparator.
Place the redstone dust in the block next to the torch and connect it with the redstone dust line connected to the hopper.

③ Install switch, block, observer and redstone dust. Set repeater next to block to maximum delay. .
(When switching on the block redstone dust glows, the observer senses it, sends a pulse signal to the back block, and the circuit remembers)

Please enjoy the bingo game when you play Minecraft with your friends.

I think that mining and architecture are also fun. Sometimes I feel refreshed, how about a bingo game with my friends?）
