Your only objective in the online game Infinite Stairs Online is to advance your character as far as you can. You'll be sprinting up the stairs while veering in different directions. The issue will be that you can only stop for a little period of time. There is a marker at the top of the screen that shrinks when you stop moving. The game will be ended if it shrinks too much. If you don't modify your course and end yourself outside the stairs, the game may also terminate. You may purchase additional characters in the store with the coins you earn. Come on then!
