Teamers are players in FFA, Experimental Mode, Party Mode and Battle Royale who work together with other like minded players to get to the top of the leaderboard. In Teams Mode, a variation is Cross-Teamers, working together with players from different colours to get big.

In Party Mode, there is no problem with teaming since that is what the mode was made for. However in FFA and Experimental Mode, as well as cross-teaming in Teams Mode, teaming goes against the morals of those modes, and is often hated.

Example of a player with a name often used by teamers.

Teamers often use names such as the name of some YouTuber, name of a person in a clan, "w=team", "w=ally", and "w=friends". Teamers may also use another, similar variation of these usernames. 

Teamers objectives are slightly different than that of the typical FFA player. Teamers usually work in conjunction with other Teamers to gain mass. The strategy that they use to do this, however, differentiates from the common strategies used by a lone player due to the fact that they are working symbiotically with another player.

This fact opens up a plethora of different options in terms of strategic maneuvers in regards to Splitting and other methods of gaining mass through the consumption of other player cells.  

Teamers will Eject mass towards one another to signify that they are in cooperation. Looking for this act is a way to figure out which players are Teamers if it's not already in their name.  

Teamers generally share the mass that they gain between one another, and the fact that they are working together to hunt other cells makes them a very high threat to those who are playing FFA solo.

Types of Teamers:

Type of Teamers Description (and how to beat them)
Force Teamers Teamers that help you without verifying that you and that person are working together. Usually, they'll start feeding you, most of the time because of your mass.

How to beat them: If you are being force-teamed, just keep a strong mind and reject them. They will have to go away since anyone in the right mind won't take on a cell that is 20 times as big as them.

Random Teamers Teamers that'll help anyone they please, for one situation. They'll help someone get a kill, or not get killed. After, they'll go about their business.

How to beat them: These people are quite annoying if the enemy is on the receiving end of these people. If you are skilled enough, random teamers won't really be a problem, as you could still beat the enemy cell if you are skilled with viruses, self feeding, and splits. 

Regular Teamers

They help each other, helping each other get to number one.

How to beat them: Kill their teammate as soon as one of their cells feed all their mass to the other cell. The bigger teammate would be forced to fight you, or team with another cell/possibly the same cell that you just killed, that respawned. You would have a chance to hit the bigger teammate with viruses once you kill their teammate, and possibly eat them, or at least worsen their anti-team penalty effect. Also, if they try to do a tricksplit on you or something like that, split at just the right time to eat all of their pieces.

Bot Teamers

People who team with a bot.

How to beat them: You can't really do anything. Try shooting viruses at the person and hope that anti-teaming will activate.

Fake Teamers People who eject (W) to a far away cell, only to split-kill them once they trust the Fake Teamer.

How to beat them: Simple. Never trust anyone in FFA and Experimental. In party, you could play with friends that you know irl, or even team with yourself (multiboxing) if you're really up for a challenge.

INA Teamers People who eat others and keep feeding his teammate.

How to beat them: These are really annoying. There isn't that much things you can do, but try to shoot viruses at the bigger teammate and wait for the anti-teaming penalty to hit them, and try to avoid them until you are near their size. Also, if you are big enough, kill the smaller teammate who is eating others and feeding his teammate. That will leave the bigger teammate without a partner and so he would have to play solo.

Cross-Teamers In Teams Mode, players who team with other player(s) from a different colour from their own, sometimes even betraying their own teammates by helping cells from other colours eat them.

How to beat them: Good ones are very hard to defeat, nearly as hard as slow-teamers. Thankfully, they are usually much less skilled than slow-teamers, and they can't farm viruses in team mode. When the opportunity arises, eliminate all the xteamers that are of a different colour from your own, completely. This way, the ones remaining (which are same colour as you) won't be able to eat you. Virus them at every opportunity to give them Anti-Team Penalty. You can see more here.

Slow-Teamers Large teams, constituted of a giant cell and a smaller one. The giant cell will split into 16 pieces, being protected by a teammate, and will only give the mass to the teammate when in danger. They are not hit by anti-teaming, due to acting slowly.

How to beat them: These are the hardest to defeat, and some of the most annoying. You would need: Skill, endurance, and very good luck. You need to grow to a size where you could double split and still be able to eat the slow teamers when the giant cell is split into 16, but this is easier said than done. If you are lucky enough to survive until you can confront them, Then quickly double split on the giant cell, and hopefully you can eat all of the cells quickly enough so you can eat the teamers. If you fail, or activated the anti-teaming penalty due to them shooting viruses are you, feed all of your mass to someone else that also is against slow teaming. If you are big but not large enough to double split on the giant cell that has split into 16, then you can split once and eat one of the cells, then quickly split again to eat the other pieces. Hopefully, he will react slowly so that you can eat the teamers.
