Karl didn't know, but he knew that if he was annoyed like this any longer, he would revolt himself.

So, on the weekend of the first week after the Christmas break, Carl made fifty sets in a row.

With the first set, the second set is much easier to make, but only relatively speaking.

The crafting itself wasn't difficult, and there were a lot of copies with the Copy Charm, but Carl had to stay up two all-nighters to copy each card.

Then, he gave them all to the twins, and finally cleared them for a while.

But now, the whole Hogwarts is completely lively.

The twins were really not business-minded, and the first thing they did was to write a letter to help Carl apply for a patent for a patent from the Ministry of Magic's Patent Office for Funny Products, which was the first time Carl had heard of such a department at the Ministry of Magic.

George and Fred then got the idea into the game's pack-opening mechanic.

When Carl first made this game, he just wanted to imitate it completely, so he made the card pack and pack opening mechanics as well.

The fifty sets he made, in order to save trouble, each set is a table and a full set of card decks, and he didn't think about it that much at all.

However, George and Fred simply took the tables and cards apart.

They are ready to sell separately.

Buying a table only gives you thirty basic neutral cards, and the cards are completely random, but fortunately they don't repeat - Carl looks confused, and George and Fred even add the basic cards to the card pack.

However, in terms of randomness, the twins did not make a fuss, it is indeed completely random, according to the two, they can make money, but they will never lie.

As for the price, even Carl can't sigh, the two of them are too black-hearted.

A table costs five Galleons, which is expensive, but bearable, after all, it is the basis of the whole game.

But the card pack, even Carl can't stand it anymore, they actually sell a Galleon for a card pack!

In those days, most of the young wizards' possessions were only a few Galleons, and their pocket money was calculated on the basis of a west.

At this price, if you have a black face, if you want to buy a complete set, the average wizard family will probably have to go bankrupt.

Not only that, in order to prevent piracy, in addition to Carl's original original, they had Carl apply a series of protective spells such as anti-copying charms and anti-disassembly charms on each copy, and printed the anti-counterfeiting seal they designed on the back of the table.

What's worse is that the twins shamelessly let Carl add identification magic to each card pack and card, and the cards he opened can only be used by himself. This directly eliminates the possibility of private transactions.

If you want to get a new card, you have to buy it from them.

But this did not dampen the enthusiasm of the little wizards in the slightest.

On Monday, when George and Fred announced the start of sales in the Gryffindor common room, the young wizards in the room went crazy.

Seeing the young wizards desperately stuffing money into George and Fred's hands, Carl was a little worried, and he was really afraid that some young wizards would do something bad to get the money to buy the card pack.

Soon, however, Carl realized that he was too worried.

George and Fred didn't sell card packs at all.

The little wizards paid for the tables and the basic cards that came with them.

Considering the purchasing power of the young wizards, coupled with the number of people at Hogwarts, Carl thought that the fifty sets of Hearthstone he made should be able to meet the needs of the entire Hogwarts.

But he was still too naïve.

In less than half an hour in the Gryffindor Lounge, George and Fred sold out all fifty tables.

With Fred and George's deliberate explanation, in order to get more basic cards, many young wizards in the upper grades directly bought two sets.

As a result, even in Gryffindor, there are many young wizards who have not bought the goods.

Looking at the expectant eyes around him, Carl could only say weakly, "I'll do it again on the weekend." ”

Immediately received a cheer.

Because it's a new game, Hearthstone's name isn't on the list of prohibited games on the door of Folch's office.

So, in the following week, there was a very peculiar phenomenon throughout Hogwarts.

Whenever there was no class, no matter where they were, in the Great Hall, in the courtyard, or anywhere else, there were always two Gryffindors sitting facing each other, with a plate of Hearthstone in the middle, and the wizards of the other three houses gathered around the two of them and watched intently.

After a while, when one of the heroes yells "I choose to die!" or "You, win!", there is a sigh or cheer all around, and then everyone starts to count the losing one.

"When you were five people, you should have produced that entourage!"
