Previous Post Unblocked Unblocked Description Unblocked is a massively multiplayer online action game created by Brazilian developer Matheus Valadares. Players control one or more circular cells in a map representing a Petri dish. The goal is to gain as much mass as possible by eating agar and cells smaller than the player’s cell while avoiding larger ones which can eat the player’s cells. Each player starts with one cell, but players can split a cell into two once it reaches a sufficient mass, allowing them to control multiple cells. The name comes from the substance agar, used to culture bacteria. Unblocked was released to positive critical reception; critics particularly praised its simplicity, competition, and mechanics, while criticism targeted its repetitive gameplay. Largely due to word of mouth on social networks, it was a quick success, becoming one of the most popular web and mobile games in its first year.

A Steam version was announced on 3 May 2015 (though never released as of May 2019), while the mobile version of for iOS and Android was released on 24 July 2015 by Miniclip. Unblocked has inspired similar web games called “.io games”, including games with a similar objective but different characters, and games that incorporate elements of other genres like shooter games. Unblocked Gameplay

The objective of Unblocked is to grow a cell on a Petri dish by swallowing both randomly generated pellets (agar), which slightly increases a cell’s mass, and smaller cells, without being swallowed by even larger cells. The browser version currently holds five game modes: FFA (Free-For-All), Battle Royale, Teams, Experimental and Party. The mobile version of the game includes FFA (Free-For-All), Rush Mode and Battle Royale.

The goal of the game is to obtain the largest cell; players must restart from a small cell when all their cells are eaten by larger players or fountain viruses. Players can change their cell’s appearance with predefined words, phrases, symbols or skins. The more mass a cell has, the slower it will move. Cells will gradually lose a small amount of mass over time.

Viruses are green, spiky circles that split cells that consume it. Viruses are normally randomly generated, but can also be generated when receiving enough mass, to the point of splitting into two, hence creating a new virus.

Players can split their cell into two, and one of the two evenly divided cells(if the mass of the original cell is odd, one cell will be slightly bigger than the other) will be shot in the direction of the cursor when the space bar was pressed. This can be used as a ranged attack to shoot a cell in order to swallow other smaller cells or to escape an attack and move quickly around the map.

Split cells merge back into one cell if a bigger cell of the same player’s consumes it. Aside from feeding viruses, players can release a small fraction of their mass to feed other cells, an action commonly recognized as an intention to team with another player in Unblocked. Unblocked Development Unblocked was announced on 4chan on 28 April 2015 by Matheus Valadares, a 19-year-old Brazilian developer. Written in JavaScript and C++, the game was developed in a few days. The game originally did not have a name, and users had to connect to Valadares’ IP address in order to play. The name was suggested by an anonymous user on 4chan, as other domain names such as were already taken.

Valadares continued updating and adding new features to the game, such as an experience system and an “experimental” game mode for testing experimental features. One week later, Unblocked entered Steam Greenlight with Valadares announcing a future free-to-play version of the game for download.

He planned to include features in the Steam version not available in the browser version, including additional gamemodes, custom styling, and an account system. It was approved for listing on Steam due to community interest. However, the Greenlight program was shut down in 2017, and the announced game has yet to be released.

On 24 July 2015, Miniclip published a mobile version of Unblocked for iOS and Android. Sergio Varanda, head of mobile at Miniclip, explained that the main goal of the mobile version was to “recreate the gaming experience” on mobile, citing the challenges with recreating the game on touchscreen controls. Unblocked Reception Unblocked was released to a positive critical reception. Particular praise was given to the simplicity, competition, and mechanics of the game. Engadget described the game as “a good abstraction of the fierce survival-of-the-fittest competition that you sometimes see on the microscopic level.” Toucharcade praised its simplicity, strategic element, and “personality.”

Criticism was mainly targeted towards its repetitiveness and the controls of the mobile version. Tom Christiansen of Gamezebo was mixed on the game, saying that there was “nothing to hold my attention” and that it was “highly repetitive, overall.” Pocket Gamer, reviewing the mobile version, described its controls as “floaty.”

Because it was frequently propagated through social media and broadcast on Twitch and YouTube, Unblocked was a quick success. The website (for the browser version) was ranked by Alexa as one of the 1,000 most visited websites and the mobile versions were downloaded more than ten million times during their first week. During 2015, was Google’s most searched video game.

It was Google’s second-most searched game in the United States in 2016. A 2015 press release by Miniclip stated that Unblocked was listed as the fifth top game on YouTube’s list of top has inspired similar web games called “.io games”, including games with a similar objective but different characters, and games that incorporate elements of other genres like shooter games.

During the campaigns of the June 2015 Turkish elections, Unblocked was used in Turkey as a medium of political advocacy; many players were naming their cells after Turkish political parties and references, with alliances formed between players with similar political views, battling against other players with opposing views. Some political parties have used in campaign posters as a symbol of support. Unblocked was featured (including some details of its gameplay as well as a shot of an actual game) in “Chapter 48” of Netflix TV series House of Cards. Its gameplay was compared to the presidential campaigning. Unblocked History

  • The favicon of the browser tab used to become the color of your cell, or your cell’s skin. However, nowadays that does not happen any more in Unblocked.
  • Unblocked was created by a biologist (Zeach)
  • On 13 July 2015, some FFA servers were really huge, had 20 places on a leaderboard and you needed more than 6k mass to get on it.
  • On 7 November 2015, you couldn’t split on all official servers. Cells were not bigger than 22k and viruses could gain 500+ mass.
  • On 12 February 2016, everyone who died would get to level 100 quickly. XP would not stop gaining, so even if you were on a small level, in a few minutes you could get the Kraken skin.
  • Agario Skins – informational website, where people can find guides and full list of skins.
  • The game can be modified and extended with custom scripts.
  • It was possibly inspired by the game Tidepool on
  • There are a lot of Agario clones which have similar design, but different game mechanics. Some of them are:,,,

All game modes


Virus tactics

  • Find an area with three close viruses. Stay there for a while and wait for big players to pass. Split them using eject function, and then do something strange; don’t eat them, eat the players that come to eat them. You will gain more mass this way.
  • If you are around 200 mass and have cornered a 100 mass player in a virus, here is a simple trick to eat them; split twice into them. They will eat one of your pieces, and become too big and pop on the virus. Sometimes you may even absorb all their small pieces entirely. If not, you can split kill them. This is known as a mini popsplit.
  • When shooting a virus, always make sure they will
    • Be hit by it;
    • Be close enough so you can eat some and
    • Make CERTAIN you have enough mass to fire, and still be big enough to split for the small pieces afterwards (~300 for a fresh virus) If you don’t, you will almost be as small as a newly spawned player and for nothing.
  • You can hide in viruses and wait. Wait until someone comes dangerously close to you, then quickly get out and eat them or wait a little bit longer until someone smaller than you thinks that the virus you’re in is empty but in reality they just got eaten and killed. If you eat a player that brings you to over ~120 mass, move out of the virus IMMEDIATELY!!! If you get any bigger, you will ultimately split to death.
  • Find a perfect small virus, have a mass of 120 and make sure no one saw you in the virus. Players only see you as a cell but not the virus and looks like you are “away from keyboard”. Then when a larger mass comes to eat you like any other cell does to “away from keyboard’s”, quickly get back and the player explodes.
  • Split onto a virus. After that, keep on eating other viruses. You will not split more as long as you don’t combine.

Strategy by mass

When you are small (10 – 120 mass), just eat the ever – spawning pellets. It is OK to go into the viruses temporarily to escape larger players, but do not use it as a strategy.

When you are medium-small (121 – 280), you should start eating smaller players. It is a bad idea trying to hide in a virus as you will get split.

When you are medium (281 – 500), you should start trying to team or shoot viruses into larger players. Now you can (probably) accept the W pellets that players use to lure smaller players as you might be too big for them to split on you. Beware that many giant players use the blob-luring technique.

When you are large (501 – 1000), you can use the blob-luring technique too. Beware that smaller players might shoot viruses into you now.

When you are giant (1001 – 10000), you will start losing mass quickly, forcing you to eat smaller players. You can split into a virus and wait for a small player to eat your smaller cells. Once a player comes, split and eat them.

If you are larger than this (10001 and greater), you may be forced to stay in a small spot as viruses will block your path. You should just eat the viruses (after you have already split into 16 cells), as many players will not be able to eat your larger pieces.

Split tactics

  • There are three fundamental rules to splitting.
    • Never split unless you are sure no viruses or big players are ahead.
    • Be sure that you know you are at least 167% bigger than they are before splitting. You need 33% more mass to eat them when split.
    • Be sure you are splitting for someone worth it. Small cells are tough targets and a risky choice.
  • When you get to 35 mass, split IMMEDIATELY. This way, you’ll have a significantly larger view, a wider area for collecting pellets, and a higher speed.
  • If you’re sure there are no larger players around and you find a rich field of small dots, you can split once or twice to decrease your mass, increase your speed and surface area to more quickly “eat” the dots in the rich field to gain mass. As you eat more, your parts will begin to re-coalesce. Occasionally this can be dangerous, if a larger player stumbles upon you, as you will be more edible and they may split to consume your smaller parts. On the plus side, you’re smaller can can often “get away” by outrunning them.

General Survival Tactics

  1. If you are bigger than someone but are split in half, find a wall and W key until you have a microcell and a huge cell. You can easily afford to lose that tiny cell, and will scare off most enemies. (BEWARE: Only 14 out of the 16 mass in ejections are absorbed, so use this sparingly!)
  2. If you’re about to be mowed down by a larger player or mob of larger players and don’t want to die, split in order to decrease the mass of both / all parts to get away with at least some of your mass intact. Sometimes, you can even get away with all of your mass intact, albeit in smaller pieces. Once you get away, find a rich source of tiny cells to eat and grow or eat until you merge.
  3. Sometimes you will be chased by an opponent your size or slightly larger. Just stay ahead of them and find dots to consume. Since you’re in the lead, smaller and can stay ahead of them, you’ll eat the dots and grow in size to their size or larger, at which point they’ll usually break off and leave you alone.
  4. Risky survival: If you’re being chased by a larger opponent, and chased toward other large(r) players, you can sometimes survive by keeping equal distance between them, but risking getting slightly close to the larger player, since the smaller of the two larger players will not want to risk being eaten by the much larger player if 1) they get too close or 2) they split to eat you, but their parts become small enough for the larger or equally sized opponent to then eat. This can sometimes backfire if the larger player decides you’re a worthwhile meal, splits, eats you, and goes after the slightly smaller larger opponent after that piece grows due to eating you. But this does work about 1/3 to 1/2 of the time as a last resort when you’re being overrun by larger player(s).
  5. If you have between 130 and 300 mass, you can feed a virus and hide in it for survival. Only do this when absolutely necessary. Do note that others can still shoot the virus and you will pop, or they can still mini popsplit you.

Social tactics

  1. You never want to be #10 on the leaderboard. Why? You will be a target for the big leaderboard players who have almost none worth eating. Also, your name will be given away so future enemies know to target you as you are near-board size.
    1. Don’t impersonate YouTubers. This leads to the YouTuber in question being forced to use different names. Don’t impersonate the names that the YouTubers use in their videos as well.


  • Find a Spawner Cell and feed your spawner cell then your spawner cell immediately becomes bigger and then eat the mass your cell dispenses and scare away hungry bandits that want to eat the pellets the cell dispenses!
  • when your very big like 12K+ mass split 16 times and eat the spawner viruses they give 200 mass and also you don’t split eating them when split into sixteenths.


Stay near a big player, and try to receive mass that is either split. Another idea is to build mass, and split other players. This institutes a high variety of split cells that can easily be consumed.

Battle Royale

In a Battle Royale, usually, around 20 to 40 players are put on a server to see who can survive the longest. Players are forced to stay in the safe area as it shrinks. Going into the red area or hazard area will split and shrink any cell until it completely disappears. Players must eat mass to grow bigger while watching out for opposing cells. Once eaten, players are forced to leave the server, but can still spectate. As the safe area shrinks, players are forced to move closer to each other, making survival riskier.

A player’s cell should be in one piece near the end of the match. Also, a mass of around 300 will allow the entire safe area to be visible. Only shoot viruses if the targeted player is directly in front of or almost on it as it will result in quick mass loss. Make sure to be the smaller cell when directly on another player. So, when the safe area shrinks, the opposing cell will hit the hazard first. Good Luck! Unblocked Image Unblocked Walkthrough Video
