A level must be rated Demon in-game in order to be considered for placement on the Demon List (the "list"). By using RobTop's rating system as a standard for list placement, we avoid the otherwise inevitable scenario of the list being filled with nearly impossible challenge levels or "joke" levels. At no point will there ever be a list that covers unrated levels, as it would be highly variable and difficult to maintain.
Although the Legacy List contains levels that are easier than anything in the Extended List, a level must be considered harder than the easiest Extended List demon in order to be placed. The only way for levels to be added to the Legacy List is when a current list demon no longer qualifies for the top 150.
In addition, the list focuses on levels verified by a single player, even if the level itself uses the 2-player gamemode. For instance, if "Codependence" was rated, it would not be placed on the list because it was verified by more than one player.
A rated level is only guaranteed to be considered if it has a corresponding legitimate verification video. Levels with hacked verifications that remain rated may be placed as long as it has at least one legitimate victor. Level hosts may choose to identify this victor as the official verifier per our verifier guidelines.
The list team strives to place list-worthy levels as efficiently as possible; we want to place them accurately without sacrificing too much time gathering opinions. In general, a level will not be placed within one week of getting rated in-game unless it has at least three victors with reliable and consistent opinions.
If there is strong variation between existing opinions, the team will likely wait longer than one week to determine an accurate consensus. The only exception to this guideline is if the level is widely regarded as the hardest demon in the game; we'll likely place it at #1 soon after it gets rated.
After one week has passed, we'll continue to monitor the opinions of new victors in an effort to detect a consensus. If there are enough victors for us to determine a consensus with little variation, we will place the level promptly. More details regarding our analysis of opinion sheets can be found in these guidelines.
Even if the level does not have a clear consensus, or if the opinions have a lot of variability, we may still place it if it becomes clear that no new victors will emerge anytime soon. We place levels in this manner to encourage more players to complete them for list points, but these placements are likely to change when we start seeing new victors with updated opinions.
We will place a list-worthy level no more than one month after it gets rated in-game, even if it has little to no victors. Such levels are highly subject to change in the future as players eventually complete them.
Please note that these guidelines does not apply to levels with a hacked verification; the one-month timeline for a hacked level begins after it receives its first legitimate victor.
In addition, this one-month timeline will reset if the level receives an update with a legitimate verification, regardless of whether it was placed prior to the update.
Placing a level on the list often results in it receiving new victors as players attempt to beat it for list points. As such, several of the new victors may say that the level should be either raised or lowered from its initial position.
If we hear of multiple victors for a level suggesting its reevaluation, or if a staff member completes it and proposes the change to the rest of the team, we will likely begin to collect opinions from recent victors and add them to the initial opinion list.
We will also begin collecting new opinions if the level receives a legitimately verified update that noticeably alters its difficulty.
The analysis of an opinion list for existing list demons works similarly to how we determine new placements. However, greater caution is exercised in cases of high variation. If a placed level has split opinions (for example, several people find it underrated, while several others find it overrated) from new victors, it is unlikely that the level will be moved unless a stronger consensus appears.
In addition, some of these existing levels may have been on the list for a very long time, so it's possible that the opinions from the earlier victors would no longer be valid due to new levels getting added over time. When we consider a change to an existing placement, we tend to emphasize the opinions from the more recent victors. As a rule of thumb, players that completed the level over one year ago are usually not asked for updated opinions.
Each level page on the website features a list of creators, which consists of those considered to have made a significant contribution to the gameplay and/or decoration in one or more parts of the level. In general, the list team only adds creators that created "standalone" parts for the level; their contributions must not merely append to the work of another creator. For example, a creator that creates the block design for a part in the level will likely be credited, but someone that adds glow to every decorated structure will not. This guideline applies to both gameplay and decoration.
In some cases, other individuals that played a major role in the level’s development may also be credited on the creator list. This guideline includes level hosts and optimization teams, but does not include playtesters. Other “edge cases” in which the contribution may or may not be significant enough to qualify will be handled by the list team on a case-by-case basis.
In addition, a qualifying part for the creator list must serve as a reasonable route to complete the level in question. In general, the verification route will be the one considered “official” in regard to generating a creator list. Some levels contain offscreen parts that have unique creators but are not featured in the level's completion route. These creators will not be credited on the level page.
Some list demons are “megacollabs” with a designated host. If the original verifier of a list demon megacollab is removed from the stats viewer, the host of the collab has the right to change the verifier as if the level had not been released yet. A corresponding legitimate completion will be counted as a verification on the level's webpage.
