So...  Anyone have advice on how to fully shuffle a deck of 1500 cards?

Do a magic the gathering shuffle.

Throw them up in the air and then collect them? 

Kind of related to this, I had a professor once who needed to distribute a few papers through a 150 person classroom.  He took the fat stack of papers and threw it as hard as he could, and it was by far the fastest way to distribute papers to that many students.

I feel like you're underestimating how big of a pile that is...  I don't have any space big enough to do this without risk of bending or losing cards.  If I had a gym at my disposal, then maybe.

If you are okay with the cards being very mildly damaged, then put them on the largest surface area you have available and uhh do the children-shuffle thing... somehow it's hard to describe the technique. Which is actually the most effective way to shuffle cards.

If they are valuable, like MTG cards, well then you have to divide them into a lot of piles, shuffle them individually, and then merge them. That would take a lot longer.

I think it is called the scramble shuffle?  Or some people call it the smooshing method.

Nah, the smooshing method/mash shuffle is similar to a riffle shuffle but without the bending.  It also requires sleeved cards.

The reality is you need to separate those 1500 into 15 stacks of 100 or so, shuffle each stack thoroughly, move half of each stack to the next stack, shuffle thoroughly, repeat, um, 13 more times, then stack the piles together.

Or get a casino shuffler, though even those likely can't do more than ~500.

Can I ask what sort of game this is?  Or are you creating a Battle of Wits deck?

I always thought that the mash shuffle was like the riffle shuffle, but the smooshing method was shuffling the cards like a five year old (or me when I am playing dominion with not very many cards.

[sudgy]

It's a homemade card game.  We cut eight cards out of a normal piece of paper, and we've made a lot over the years.  I do have them sleeved, for what it's worth.

The problem with the smooshing method is that I still think there's not enough space anywhere.  I've noticed that if you don't have enough space it doesn't shuffle all that well.

My current idea is getting a bunch of random numbers and using them to assign each card to a random pile (like one person just yelling out "Three! Seventeen! Eight!" while another person has the deck), and then shuffling the individual piles.

[Axxle]

I think that's also called the Wash shuffle, where you basically scatter the cards on the table and shuffle them like dominoes.

How random do you need it? My thought is:

1) split the cards into manageable piles (let's say 10 piles of 150)

2) riffle shuffle each to sufficient randomness (8 times I think for those sized piles)

3) reseed the piles (split each pile in tenths and make new piles from each old pile)

4) repeat steps 3-4 a number of times equal to the original number of decks (so 10 times)

That's like 800 riffle shuffles so might be overkill, but I think it's correct. My concern is with the number of repeats, but if I imagine each starting subdeck as completely homogenous and distinct, I think it takes that many iterations to work.





Alternatively to be absolutely certain just roll 1499 dice of decreasing value.

[gkrieg13]

I guess it also depends on how shuffled you need them.  If you could, another idea would be to just have a RNG tell you which card to pick from the stack.

So maybe have 20 stacks or something, and just pick a random stack, then a random card from that stack.

That's pretty interesting, split the deck into 20, riffle shuffles each, number them, and then roll a d20 each time you need to draw. No need to choose a random card if that deck is already shuffled

beautiful description!

[Witherweaver]

Just get bigger hands and riffle shuffle!

I thought the Wash shuffle is where you randomly stick a spear and hope to get what you want.

Does an egg from an evolution of Eevee hold an Eevee or that evolution?

[pacovf]

Don't eggs always contain the earliest form of a Pokemon?

[Awaclus]

Most eggs I've seen have just contained a bunch of white and yellow stuff, no Pokemons.

Along with protein and healthy fats.

And lipoproteins, which are amazing for a bunch of cooking and baking applications.

I hope so! Otherwise I made a huge mistake in evolving my Eevee. I didn't know there were the possibility of breeding in firered.

Lucky you. You can't imagine how annoying it is to want to eat an omelette just to find yourself trying to contain a Lapras trashing out your kitchen.

how did you know that the egg I just got 10 seconds ago contains a Lapras? :-O

That's because you killed it.

Time travel.

But mostly, Lapras is a large pokemon that doesn't have pre-evolutions, which made the joke funnier.
