Day after day on the internet "Why did not I remember this?" different ideas, different applications do not emerge. As human beings, we like to consume products, or rather, "facts" quickly, so we are transferring our consumption needs to virtual environments like the internet. Here, at this point, we have a very simple application that can actually be produced in a matter of hours, arising from the need for "diversity": agar.io
Agar.io is actually a network-based game. The only thing you need to play this game is an internet connection. Do not look at the game, there is no side of the game, obviously: no graphics, no sound, no music. Despite this small practice, "What is addiction?" "Addictive agar.io'dur." it became a phenomenon that would give the answer. The logic is fairly simple: we are a round cell and our goal is to "grow", then "swallow" other cells and grow even bigger. I feel like you're taking your metaphorical attention. Anyway ... The game is based on such a simple rule. As a newborn cell you can be swallowed by others in the thirds or you can expand as the largest cell so that others are around you.
