how to get the Almagest jackpot
The Algamest Casino is home to a well known jackpot, so be prepared to fight for it.
Starfield goes for that pristine retrofuturism aesthetic for a lot of its city design, but even with how pretty the cities are, people still want to get away once in a while.
Starfield has a number of unique locations all across its sprawling galaxy, one of which is the Almagest Casino which can be found in the Olympus system right by Nesoi. If you're looking at the galaxy map you'll see a little spaceport icon next to that planet, and that's where you want to go.
So if you're looking to recreate that one really bad scene from Star Wars: The Last Jedi by heading to a space casino to grab some loot, that's possible in Starfield as the Algamest Casino is home to the Algamest jackpot. But with a well known jackpot up for grabs, you can expect other travellers to be searching for this loot too, so make sure you're stocked up on weapons and ammo before docking, because the spacers aren't up for sharing.

Once you're in the casino you'll notice that everything is in zero gravity, so feel free to float around. You'll want to head towards the spacers and take them out, but before you can, you should run into a vault door being guarded by them which you can head up and open, but you'll be prompted to enter a code to open it up.
Finding the code is a bit tougher. You'll want to make your way to the second floor of the building by heading up from where the vault is. Afterwards you'll want to look for a small office room which should be in view from where you are. Head into that office and you'll find a computer terminal, and unsurprisingly, you'll want to take a peek at the email labelled 'Jackpot Combination'.
Within the email is a warning to whoever worked in that office to make sure there are no jackpot winners, and to avoid the winning numbers, which are 12, 19, 36, and 5. Head back to the vault and you'll be prompted to enter numbers in a specific order through multiple choice answers. Simply put 12, 19, 36, and 5 in and you can crack that vault open and run away with riches beyond your wildest dreams. Opening the vault will net you a whopping... 3,700 Credits.
Considering you had to kill a bunch of people to get to this the jackpot wasn't really worth it, but maybe it's a metaphor about how gambling isn't worth it, or just a boring reward.
