XP Farming

XP Farming is a term many players use to refer to the most effective way to earn XP for each run. Due to the recent level cap increases to level 60 and soon to be level 70, there are many coin, crystal, and treasure rewards that comes with reaching each level. Some treasures like the Lv.50 Golden Club Trophy and the coming Lv.60 Golden Club Trophy can only be obtained through reaching these level tiers. The objective of XP farming is to earn the most experience points in relatively short runs, or to earn the largest possible experience points in long runs, using combinations of cookies, pets, treasures, and boosts.

'Extensive testing has been done and confirmed that for each second of the run, player receives 10 base XP point. Other factors like bonus time, points, and coins do not contribute to base XP gained. '(Without any XP bonuses, the XP gained at the results page can be divided by 10 to determine the time spent in seconds on the run.)

Below are some of the favorite ways to farm XP.

Short and Sweet
The goal of this combination is to maximize the XP bonus from all areas: Cookie, Pet, Treasures, and Boosts without the use of a relay boost for a relatively short single cookie run. A clean run can net upwards of 7k XP depending on the treasures used.

For those who do not have access to Brown Balloon since it was an event pet, other options for pets would be for Coin generation simply because there's no pet that would decrease your speed and extend your time on an easier stage. Feel free to farm XP and Coin at the same time.

Short and Sweet 2
This is an alternative for those who do not have access to Brown Balloon. With this combination you have an alternate source of 15% XP bonus from the Strawberry Cookie + Flowercopter combo, but this would require the use of a relay.

Slow Grind
Since XP gained is not dependent on anything but the time you spend running on the main map, the Prophet Cookie is the best main cookie to use because he generates 3-5 seconds of more map time (tested and confirmed), keeping you longer on easier stages. Bright Cookie is an ideal relay giving you a solid 12% XP bonus. Pets that give you health but not movement speed is ideal. Again the goal is to run for as long as possible and doing so on easier stages is preferable than reaching stage 13 quickly and trying to stay alive there. Also, since points and coins are not contributing factors to XP gained, there is no reason for magnetic auras. Revivals however could be useful for a longer run.
