Just an agar.io clone with shitty bots. Ended up at max size, or rather, the biggest size the map can really support, which is about 350k in like 5 minutes of gameplay. Then spent another 15 minutes just sitting and spamming eject, wondering if anyone would get big enough, but never going to happen, since I am taking up the majority of the map size.

When you first start, it's fun to try to stay alive and grow your cell. But it's too easy, then you have 4.8 million score and the whole map is your one big cell. Anything that spawn is immediately eaten. Of course your high score doesn't show up in the list because you have to lose the game for your score to get saved, and you cannot lose at this point. So the only option is to exit the game, and your high score is not saved. I've done this 2 or 3 times already, so it wasn't a one-off freak accident that got me in the situation.
