Tetris 99 recently got a pretty big update. It introduces team battles. We are currently working to add this mode but if you have a suggestion(s) (rules and times) fell free to upload yours here

We can probably set two subcategories.
Two missions and four missions.
The two missions category is only available for those who haven't the big block dlc and the four missions category is for those who have the DLC. Time starts at game startup when it shows the missions list. Time ends when the last mission is completed. Is this ok?

I added the 750 lines category for Marathon. Also I made the difference between IGT and LST. IGT means In-Game Time. This means that the timer in game equals final time of the run. LST means LiveSplit Timer. For those who doesn't know what LiveSplit is, It's the best app for speedrunning and tracks time and splits. This method is used for all categories except the 40 and 750 lines in Marathon. These two categories uses IGT instead.

The TST is incredibly hard to perform but besides that if you all think that cpus are still pretty easy we'll delete the cpu limitation

In the Nintendo Direct we saw new modes. We will add new categories as soon as we know a little more of these new modes

I was thinking of a category like KO% or Kill% in both Tetris 99 and CPU Battle modes.
Name: KO%-Kill%
Rules: Do a KO as fast as possible. Time starts at GO. Time stops when the KO sound plays.
Description: This rules are general I will make specific rules for both modes.
Let me know if you agree

I want to add some new categories but I dont know the type of categories that you guys like most. So if you want to help me out I would be happy. Please post your ideas with this layout:
Category name:
Rules of the category:
Description(optional):

Thank you in advance

If you all agree with that I'll change stop time and modify all runs

I choose that stop timer because you must show the leaderboard at the end. If you want the stop timer when the game shows " X player remaining" it's ok I'll change it but in the video you must show the leaderboard otherwise the run won't be valid. If you agree with that I'll change stop time

IGT
