.io games
Multiplayer games you join in seconds: grow a snake, a cell or a tank against everyone else on the server, and start again the moment you lose. Every one of these runs right here, no download and no account.
Settlers-of-Catan style board game against real people or bots. Trade, build roads, reach ten points.
Formerly FlyOrDie.io. Evolve through 40-plus flying creatures by eating the ones below you.
Claim land on a map, balance troops against interest, decide when to attack. Hundreds of players per match and games that last an hour.
MooMoo-style gathering and base building with tameable animal companions that fight beside you.
Drive a tank, shoot shapes for XP, spend points on a build. Dozens of tank classes branch off a single tree, and the best players know every matchup.
Snake with a persistent account, evolution levels and a bug companion. Deeper than Slither, and it has ads and purchases to match.
Start as a mouse and eat your way up the food chain, one animal at a time, while bigger animals hunt you.
Claim hexagon territory by drawing loops back to your area. Cut other players' trails.
Gather wood and stone, build walls and windmills, defend your base. The windmill economy and hat system made it a genre of its own.
Physics sumo. Push the other balls off the platform. Thousands of player-made maps and a proper level editor.
An open-source spin on Diep with far more tank classes, bosses and modes. Rougher edges, deeper tree.
Slither with sweets and power-ups. Cakes, candy and potions on the map change your speed, size and magnet range.

Starve's post-apocalyptic follow-up. Radiation, zombies and scavenging, with the same unforgiving crafting loop.
You are a flower with a ring of petals. Fight mobs, collect rarer petals and build a stronger loadout.
Steer a cell around the map and eat pellets and smaller players to grow. Split to catch others, and keep away from bigger cells.
3D survival with tribes, crafting and raids. Closer to Rust than to MooMoo.
Top-down team shooter with destructible buildings, vehicles and a sizeable weapon list. Plays like a 2D Battlefield.
Your car drags a flail on a chain. Swing it into other cars, or release it and reel it back in. Simple to learn, hard to master.
Steer a line that never stops growing. Make the others crash into it.
Helicopter shooter where you also claim territory by building walls. Half Diep, half Paper.io.
A small 3D MMO that loads in seconds. Four classes, two factions, dungeons and a real economy.
The original grid-claiming game. Tighter and blockier than Paper.io, with a proper leaderboard.
A polished MooMoo-like with ages, hats and a competitive clan scene. Combat is faster and more skill-based than the original.
