The games in 2022

1., the granddaddy of them all, is an eat or be eaten game of cellular survival inspired by the behavior of microbes on top of agar medium in a petri dish, hence the name. 

Players begin as small as possible, zipping around the map and eating food to grow larger. You eventually grow large enough to engulf other player cells, resulting in a deadly cat and mouse game in which you try to entice other cells while avoiding larger swarms of players that can engulf you. Its simple but tense gameplay helped it go viral, and it was even featured in an episode of House of Cards.

2. is based on the classic game of snake, with players slithering around the map consuming motes of food to grow in size and points. Players are eliminated when their snake's head collides with the body of another snake, resulting in players abruptly changing direction or coiling around in order to trap and eliminate the unwary.

3. is yet another classic game in which players control tanks, destroying obstacles and enemy tanks to earn points and level up their own machines. A reasonably complex upgrade system allows you to customize your tank, allowing you to create bullet-hell monstrosities, agile attackers, or powerful snipers. is one of the best io games to play. It has a good replay value and reasonable depth thanks to a variety of game modes ranging from free-for-alls to team battles and more, while remaining a fairly accessible browser game.

4. is a top-down military shooter in which players choose weapons and armor before hunting each other down in a tight maze of barriers and passages. Each weapon has its own set of advantages and disadvantages, and players must weigh the mobility and protection tradeoffs of armor or the lack thereof. is a fast-paced and reasonably accessible game that includes free-for-all, team deathmatch, and control point domination modes to provide some variety in gameplay.


Players in pulverize each other with massive spinning balls of death. Starting with a small morningstar-like ball attached to your player, you'll sprint around the map collecting food, gradually increasing the size of your deathball, which you can then fling at other players using a combination of spin, planning, and more than a little dumb luck.

If the throw doesn't catch them, the return may, as holding down the mouse button summons the deathball back to the player's tail, flattening everything in its path.
