Splitting is an ability which can be used both offensively and defensively (for example, you could split onto a smaller cell to eat it, or you could split away from a larger cell). It is activated when you press the space key.
Splitting can be performed by pressing the space bar in the browser version. When splitting, all cells that are big enough will send half of their mass in the direction the cursor is facing. To be able to split, a cell needs to have at least 36 mass.
The split cells will be able to merge back together after a certain time. Steering one into the other is how to merge them back, which is generally done by placing the cursor in between the two. There is a cool down on merging cells together, meaning that a certain amount of time must pass before two cells are able to merge after splitting. The cool down time is calculated as 30 seconds plus 2.33% of the cells mass (e.g. if mass is 50, the cool down time is 31 seconds).
Consuming a virus will cause a player's cell to gain 100 mass, but forcefully be split into many smaller cells in the process, up to the maximum of 16. These are usually of equal size, but if the player's cell is too large for this, it will simply reduce in size, with many smaller and equally sized cell being split off from it. If a player already has 16 cells, they will gain the virus' mass without splitting further.
Splitting is a core mechanic in Agar.io, and is involved in many different strategies.
The most common strategy is using splitting to eat a cell which would be too fast for a quite larger one to eat. The ideal size to perform this trick would be approximately 3x bigger than the prey. The ideal scenario would be a cluster of medium-sized cells to throw the split cell to. However, a split cell, unlike a single cell, must be 33% larger than the cell it tries to consume (a single cell only needs to be 25% bigger than its target). It is also possible to profit off of the vulnerability of a recently-split large cell by eating its children via splitting, thus gaining a lot of mass. Be careful to split only when you are sure that you are sufficiently larger than the cells you are attempting to consume. Misjudging this may cause the split cell to instead be consumed by your target, which can lose you a large chunk of your mass, and may even lead to being consumed in return entirely.
Players already at the maximum of 16 cells can consume a virus or spawner with no ill effects, gaining 100 and approximately 240 mass respectively. Though it is risky to remain split into 16 cells, this allows for some very easy gains in mass, and can be a very successful strategy when done carefully.
Players often bait other cells by ejecting mass. A player with 300 or more mass, may eject 3 or 5 mass, then split on a player that attempts to consume the ejected mass.
Splitting is an important mechanic in teaming. It is preferable to ejecting mass because it is more efficient, and allows for faster transfers of mass. One strategy entails two relatively equal sized cells and a support cell. When the When your friend splits, he will give you his/her one cell. If you found a stopped player and unable to eat it, your friend give you by ejecting mass or splitting toward you.
- Splitting allows a cell to view a larger area and move quicker. The number of cells a player possesses has a direct effect on the zoom scale, with higher numbers increasing the view distance.
- Provided you have enough mass, you can split 4 times consecutively starting from a single cell, up to the maximum of 16.
- Common strategy when eating players who are baiting is double split. This involves pressing the space bar twice extremely fast.
- If you crashed to virus and you are small, hide in virus. Because virus is dangerous to bigger cells.
- Slow teams usually split in 16
