Fortnite Cipher Quests have an extra layer of complexity beyond the usual sets of assignments, as several of them are encrypted Cipher Quests that initially appear as a string of numbers. To work out what needs doing for them, you need to use a modified substitution cipher to change those numbers back into letters, then combine the words they spell out with the clues given. We've got a full explanation for the process behind that, but if it all sounds a bit too complicated then don't worry as we also have all of the solutions written out which you can skip straight to.

There are five cosmetic rewards to be earned by completing these Fortnite quests, and as two of them can only be claimed by clearing the encrypted Cipher Quests it pays to know exactly what they mean. If you're ready to crack the code, or just want to read ahead to find the answers, then here's how to decode and complete all of the encrypted Cipher Quests in Fortnite.

The Fortnite Cipher Quests are now live, with new assignments being added daily until March 7, though you'll have until March 10 to complete them. These are split into unencrypted Cipher Quests with clear descriptions, and encrypted Cipher Quests that you'll need to decode using the available clues.

How to decode Encrypted Cipher Quests in Fortnite

The encrypted Cipher Quests in Fortnite are written in a substitution cipher, as hinted in a teaser posted by Epic where "3 18 1 3 11 20 8 5 3 15 4 5" becomes "CRACK THE CODE" if you use 1=A, 2=B etc. However, the actual code used for the encrypted Cipher Quests has additional complexity as it is being offset by the digits 0.3.1.0.2.0.2.3 repeating on a loop, so you need to take those numbers off the digits in the code before converting it back to letters. Using 1.17.23.9.14. 19.19.24.1.21.6 from the first quest as an example to explain this:

1 - 0 = 1
17 - 3 = 14
23 - 1 = 22
9 - 0 = 9
14 - 2 = 12

19 - 0 = 19
19 - 2 = 17
24 - 3 = 21
1 - 0 = 1
21 - 3 = 18
6 - 1 = 5

This means 1.17.23.9.14. 19.19.24.1.21.6 becomes 1.14.22.9.12. 19.17.21.1.18.5, and if you convert that using 1=A, 2=B... then you get ANVIL SQUARE.

  • 1 of 2 - 1.17.23.9.14. 19.19.24.1.21.6 (1) = ANVIL SQUARE
    Inspect the wall... beneath eastern building at...

Head to the east side of Anvil Square to find this garage workshop, then head inside and destroy the locker next to a rack of tires to access a hidden bunker – the next encrypted code is blurrily written on the wall, so interact with it to complete the first stage of this quest.

  • 2 of 2 - 19.19.19.1.27. 1.22. 22.16.15.10.20.21. 2.17.26.12 (1) = SPRAY AT SPLITS BOWL

Make your way to the Splits Bowl bowling alley in the middle of Faulty Splits, then pull up the emote wheel by holding down on the d-pad. Instead of your usual emotes, a special Distant Roar spray will appear, so spray that on any surface inside the bowling alley to complete the second part of this quest.

  • 12.18.15.5.14.25. 14.4.2.22 (1) = LONELY LABS
    Decrypt the signal... beneath snowbank at...

Head to Lonely Labs in the northeast corner of the island, then look at the shipping containers next to the Fortnite Capture Point flag. You'll see that one of them (marked below) is sticking into a snowbank, and if you go through it you'll find stairs leading down to a secret bunker. Go down there and interact with any of the computer units to complete the third stage of this quest.

  • 19.11.2.20.22.5.20.8.4. 22.13.1.4.19 (1) = SHATTERED SLABS
    Dig at the top of...

Make your way to the northwest end of Shattered Slabs, where you'll see a series of sections cut into the hill with a small cave-like opening at the top. Enter that to find a small glowing mound on the floor, then hit it with your harvesting tool to pop an arcade machine out of the ground, completing the fourth and final stage of this quest.
