AGAR.IO SOLO solo is a fun game and recreation of solo!

About solo is like however it is single-player, the other cells have a constant velocity and you (the white cell) move much faster.

How to play

Use your mouse to move. Avoid bigger cells and eat smaller cells.


Eat small cells that are visibly smaller.

Ah yes, probably because your computer isn't allowing web storage :( I'll try to find a poly fill for you @IEDstudent

I'd say this is actually far superior to the original because there's absolutely no lag whatsoever. Beauty through simplicity; I love it!

After many attempts, I've managed to get to 259 points, but by that point, the game got so crazy I couldn't really dodge anything anymore.

Nice work! My high score is 194 lol @natiiix

@Coder100 I just started shaking my cursor when I got past ~150 and the score kept going up until I ran into a bigger circle. ;)
It's a well done small game. I like that it utilizes reflexes and mouse movement speed and precision.

My game is rigged because my trash computer is running this at like 3 fps.

very cool man! I actually created one myself, with pygame. However, you might consider making it more harder by letting there be delay between the mouse and the character. Overall, nice!
