Jackpot! is a challenge to get either three triple Eridium bars or three Vault symbols on the Lucky Shot slot machines.
The Lucky Shot slot machines are located in Moxxi's bar in Sanctuary.
Completing this challenge is purely down to random chance and will likely take many spins of the slots. The cost per spin depends on story-line progression.
Importantly, only the triple Eridium bars symbol counts for this challenge, rolling three of the single and double Eridium bars symbols will not cause it to be completed.
- This challenge shares a name with the almost identical Jackpot! challenge in Borderlands: The Pre-Sequel.
- While there are slot machines in multiple locations, the challenge can only be completed by using the slot machines in Moxxi's bar in Sanctuary.
