How many undiscovered achievements are there?

Question

List of achievements on TibiaWiki suggests that there are seventeen ID's, to which an achievement hasn't been found. This confuses me, because I've heard many people saying that there are only three undiscovered achievements. Why would that be?

Answer 1

Hey there, TibiaWiki admin here.

There are several IDs which have been skipped by CipSoft for some reason. Maybe they were placeholders for achievements they eventually decided to not implement, maybe they did it on purpose for some other reason. Either way, this is why there are several IDs with unassigned achievements, but most of them don't really exist.

As of today there are 3 Unknown Secret achievements in Tibia, of which 2 are "old" (from 2010) and one from the Summer Update 2020. You can keep track of that information here: https://tibia.fandom.com/wiki/Achievements/Unknown

Edit (Nov/2021): With the discovery of Unlikely Pathfinder, there are only 2 Unknown Achievements left.

I am not an achievement hunter and i am not familiar with the curiosities about achievements :) But I have a question for you. Could you tell me how we know that some IDs are unassigned? You know, for example, id 220 on Tibia Wiki ?

The IDs of achievements can be checked on Tibia.com on the page where you select what achievements you want to show (non-secret achievements can also be checked in the client dat files). We got the IDs of all known achievements from players that have them and some unused IDs were left over. Because they are ordered by release date we could identify the IDs of existing achievements and the IDs that were just skipped. We wrote this in a bit more depth here: https://tibiald.com/2021/05/03/achievement-ids/

Regarding 220 specifically: We cannot say with 100% certainty that the missing achievement from 9.1 is #195 and not #220. But it's not usual (I don't know if there's any case) of a skipped ID in the middle of the achievements of the same update, while it's very common to have gaps between updates. Because of that we assume that the missing achievement is #195 and that #220 was just "skipped" between 9.1 and 9.2

Thanks for the quick reply. I understand that we know from somewhere the final number of secret achievments? Therefore we can skip some of these id and consider them unused?

Yes. The number of secret achievements can be see both in game and on the website. It has always been possible to see it on Tibia.com so since achievements were released players have been tracking how many new secret achievements were implemented on each update.

Ok thanks for the reply. Now I have clarity.

According to my Source- TibiaWiki Unknown Achievements, there is now only 1 unknown achievement. I will copy and paste the chart here with details about this unknown achievement-
