Entering the checkpoint with an excess of 700 balls - expected for an experienced player.
The 1st endless mode (also written first endless mode) is the first repeat of the Endless Mode with a distance of 12,000 - 20,000. It is very commonly reached, and also playable quite a lot from the Random Rooms Glitch. Though hard for a first-time player (sometimes even reaching the checkpoint with less than ten balls), it is reachable if the right strategies are used to play through the previous checkpoints (especially Checkpoint 11.) It can be reached especially well via ball grinding, and the Perfect Method, if the Random Rooms Glitch is used. Reaching the distance of 12,000 (and after) earns the rank of:
legend, wizard, ethereal, demigod, and finally mediocre.
There is even the text Now Entering Endless Mode, with the Checkpoint ∞ logo that will appear before you head to this checkpoint via the Endless Mode Tunnel (end of Checkpoint 11).
