# Basic Dice Stacking

Ah, dice stacking. The popular pastime of stacking dice in a cup... Wait, what? You've never heard of it?

Dice stacking is the art of using a cup to stack dice. There is no trick, but a scientific principle, inertia. The dice are first picked up by the cup, and because of the motion of the cup resist movement like a bucket of water swung around. As a result, the dice stack inside the cup and slide around as if they were a single mass.

## Step 1: What you need

To start dice stacking, you'll need:

• Dice
• A cup

That's about it. More specifically, you'll need

• Heavy casino dice / standard dice / rounded-edges dice
• Speed stacks cup / yahtzee cup / short plastic cup

In order from recommended to needed.

## Step 2: How this works

When you pick up the first dice, you swing the cup back and forth, alternating similar angles. By holding the cup still on only two positions, the dice slides around the sides of the cup. The uniform motion swings the dice equally and the dice are stacked inside the cup. When you stop the dice on the table, the dice swing to the opposite side of the cup and stop, resting on the weight of the force created by sliding the cup.

See below for 2D picture example

## Step 3: Picking up the Dice

Picking up the dice may seem trivial, but it's the part most people get wrong.

First, approach the dice at a 45 degree angle. Sharply switch directions as you strike the dice, as it rises to the top, hold the cup at an almost 90 degree angle. Repeat this process until all the desired dice are in the cup. Its similar to cradling a lacrosse ball. For reference, look at my video on the introduction.

Note: Practice this away from windows until you master it. I am not responsible for broken windows or black eyes.

how do u pointstack? i've been lookin all on the web but "no dice" (lol get it :D). but pls make a tut on pointstacking and down stacking pls :D
puzzlefreak (author)  vince_935 years ago
Nice pun XD

Those are really difficult to do, especially with regular dice. I'll try to make a tutorial on it. I plan on updating this instructable soon.

Regardless, what you need to do for point stacks is essentially the same motion you do with the cup except in mid-air. The hard part is Keeping it straight. Just a warning - it takes a LOT of practice.

For downstacks, you turn on the top of the dice. Its similar to picking up a dice off a table touching nothing except the top half of the dice. This is also very difficult.

This is easier with heavier dice, but it is VERY difficult with regular dice. All I can recommend is lots of practice.

Good luck!

I'm having trouble getting them to stack once there in the can, any suggestions?

check by stooping sideways so you can peer in

Already figured it out months ago.

lol... didn't look at date
puzzlefreak (author)  lobo_pal6 years ago
Don't worry. The landing is the really hard part. Just make sure to swoop the cup along the ground and stop short. Don't slow down or swivel in a circle, just slide-stop.

I saw another video that says casino dice are easier, would you agree? And is there a real trick to stopping?
puzzlefreak (author)  lobo_pal6 years ago
I think I mentioned that in the article... Yes, I think heavier dice are easier, but to a certain degree. It's not worth getting until you master the basics. They're more for things like point stacks. No, sadly there is no trick to stopping. Try watching dennyoo7's videos on youtube and mimicking the stacking motion. That's how I learned.

do you mean denyooo6
puzzlefreak (author)  E-R-IC5 years ago
Oh, snap. That's what I meant.

I finally got it! It was tough, but I think I found a good way to learn it. Start by learning to pick up dice, than to get multiple dice, than to keep them in the cup in mid air, than up your speed. I started using a yatzee cup and went as fast as I could and now it works. You were right, I just used regular dice. If anyone watches Naruto, it is exactly the same as when he learns the rasengan. Sorry, had to geek it up there.

yeah that's what I did too... that also helps if you want to do a trick where you pre stack the dice then take the cup back and proth in mid air and pick them up as you go down.

how heavy is a heavy dice?
puzzlefreak (author)  MubiKun5 years ago
Casino dice would be best, however yahtzee dice works fine. Don't use rounded dice if you can, they're more difficult to use.
5 years ago
what i meant was the exact weight :P
puzzlefreak (author)  MubiKun5 years ago
Don't know offhand the exact weight. doesn't matter that much though.

o.k. i need help. i' using rounded dice and super cheap styrophome dixie cups. any help? or s there just no hope.
puzzlefreak (author)  E-R-IC5 years ago
No, No. 'Tis possible, but harder than it needs to be. I seriously doubt that the Styrofoam cups will do you any good though. You need to slide it across the table, so it'll probably break or not be smooth across the table. Try finding something more rigid, like a plastic cup.\ Rounded dice are okay, just a little harder.

denyoo has a new video called the evelution. the best dice stacking video ever:
I mastered this in like 10 minutes lol nice I always wanted to do this since i saw a video of it. I'm also a bit in to quarter bouncing.
puzzlefreak (author)  the_burrito_master6 years ago
You're welcome! Quarter bouncing... That's where you drop a quarter, make it land on it's edge when it lands so it bounces back up? Or something totally different?
6 years ago
sorta it's when you take a quarter and bounce it off of a table into your target like a bowl or a cup. yeah thanks a lot this is a great instructable I'm starting to do some tricks now too I can stack up the dice then I can take the cup and take one off the top every time you make the cup go back and forth. I did it with 2 dice like 3 times and with 2 dice like once or twice. then you land it and they are stacked again!

This quarter bouncing sorta sounds like an American drinking game........ :-)
