Recently, Quidd introduced the concept of set difficulty. What does it mean?

 

There are seven levels of difficulty

Beginner, Very Easy, Easy, Medium, Difficult, Very Difficult, Almost Impossible

Most of the sets in Quidd fall between Very Easy and Medium. 

As of today, only three are Almost Impossible: "Kirk’s Guide to Love" in Star Trek, "Justice for Francis" in Bob’s Burgers, and "Stay Tuned" in Breaking Bad.

 

How is difficulty measured?

The difficulty measure is based only on the items in the set and NOT on how the set is released. In other words, it’s all about the number of items and their print counts. It does not consider the packs that are created to sell the items, if they have high or low odds, when the packs are available, or if the items are released one at a time or all together. It also does not consider if the current edition is sold out.

So what does it mean for a set to be difficult?

To finish a set, you need a combination of luck, skill, and coins. These factor into the difficulty measure. The more luck, skill, and coins you need to finish a set, the more difficult it is.

Luck is when you get the rarest cards in a pack. Skill is when you negotiate good trades. Having a lot of coins means you can just keep opening packs, until you finish the set.

 

How is difficulty calculated?

As with most of our algorithms, this one won’t be published. But I can give the gist. The algorithm considers three factors: the variance of the print counts, the rarity of the items, and the total number of items in the set. Higher print count variance, lower print counts overall, and higher number of items results in a higher level of difficulty.

The algorithm is configured to assign a difficulty value to each set, which is then converted to a specific difficulty level of Beginner to Almost Impossible.

Of course, we will be revisiting the algorithm over time to make sure that it fits with expectations and may adjust it as needed.
