Infinite mode is a non-canon gameplay mode in Run 1 and Run 3. There is no storyline, and its only purposes in Run 3 are to collect power cells and the Infinite Mode achievements. It works differently in each game.
In Run 1 Edit
Infinite mode consists of computer-generated levels. The levels each have a difficulty ranging from 5% to 99%. The difficulty starts at 20%, and increases as you beat levels. Infinite mode is considered complete once you beat a level with 99% difficulty. Your progress is saved between levels.
The difficulty number is only an estimate, and some levels with a number will be harder than others. For instance, some levels with 99% difficulty are virtually impossible, though most are not. If you come across a level that's harder than it should be, click the "randomize" button in the pause menu to try a new one.
In Run 3Edit
Infinite mode consists of premade levels in a random order. Your progress is not saved between levels, so instead, your goal is to finish as many levels in a row as possible. The levels repeat if you travel far enough, so there's no way to win.
After you die, there will be the option to continue with a different character or a random character if you pay 10 power cells. You will have this option every time you die until you've used every character you have or choose not too. The respawn cost equals 10(2x)-10, where x is the number of respawns, so this can increase to very high amounts. Alternatively, you can buy the "respawn costs are reduced by 10" upgrade to get your first respawn free and all others reduced by 10 power cells.
If you die as soon as you spawn in with a selected character, you'll get a second chance, and will be able to continue onward. If this happens, a speech bubble below will say; "Whoops! Let's pretend that didn't happen."
If you choose not to continue, there will be an info box that tells you the statistics, and has a bit of trivia about the character you used last.
- On Halloween of 2016 and 2017, and for a week afterwards, some aspects of Infinite mode were altered to celebrate the holiday. Power cells in Infinite mode were given a new skin to make them look like candy corn, and the icon for Infinite mode in the title screen was changed to include a candy corn next to the words. Also, most of the levels of Infinite mode were shades of red, orange, and yellow to go with the Halloween theme. Levels would go a little bit dimmer when it's Halloween.
- On Christmas of 2016 and 2017, some days before, and a few days afterwards, power cells were given a skin to look like snowflakes, some boxes were given a skin to look like wrapped presents, some normal tiles will be changed to ice tiles, and the menu icon had a wrapped present next to it. Also, most of the levels were shades of red or green, which are traditional Christmas colors.
- On Easter of 2017, and for a week afterwards, power cells were given a skin to look like Easter eggs, and the icon for Infinite mode in the title screen was changed to include an egg next to the words. Also, most of the levels were pale, lighter shades of blue, green, white, yellow and pink, because pastel colors are usually associated with Easter.
Recycled Levels Edit
A small yellow octagon level was scrapped from Infinite Mode. It was recycled as Plan C, part 10.
On Run 3, several achievements must be earned in Infinite Mode.
A Journey of 1000 Light-Years - Run 800 meters in Infinite Mode.

I Would Bounce 500 More - Starting at any point after 500 meters, travel 500 meters in a row with the jump button held.

Asterisks mean this can only be done on a certain level.
The number after the name is the ID of the level. Pause the game and click on the crown to see the ID of each level. If you want to see a gallery of all the infinite mode levels by ID number, click here.
