25 Balls Glitch

The 25 Balls Glitch is a minor glitch where the player restarts its game from a 2nd or 3rd endless mode, or during the Random Rooms Glitch and gets 25 balls, which has similar ballcount as the Starting Stairs from the starting point, theintroductory stage.

Restarting from the 1st endless mode has zero effect on it, and you will just have your normal ball count. Unless you know which endless mode the room is from (all the endless modes are the same apart from position according to the game.xml file from its assets), you can't even tell what will happen.

Restarting in a room at a checkpoint you never reached before will make you go out of balls! (Because you haven't reached it yet, so you cannot have any balls.)
