The Father and Son safe combination in the Great Circle involves a code and some swirly handwriting

The Indiana Jones Father and Son safe code pops up after completing A Nun in Trouble, where you'll get a key from Gina for completing that objective. That opens a door to the safe and the combination to opening it involves using an Italian poem and a Polybius Square diagram to decipher it. But the heavily cursive handwriting could cause you trouble trying to read those letters so here's how to solve it.

When you complete A Nun in Trouble, Gina will give you a key that opens a door you passed earlier in her rescue mission. It'll let you access a balcony that leads to a room with a dog and cat inside, as well as a safe.

Exploring the room will uncover an Italian poem and a Polybius Square diagram:

The ringed letters in the poem give you columns and rows for the Polybius Square, which in turn should give you the code for the safe. The only potential difficulty here is that the overly florid cursive writing makes it hard to read the very curly writing. While nearly all the letter can be hard to make out the it's that last letter that causes the biggest issues because while it looks like an 'a', it's actually an 'o'. Once you know that, pairing the ringed letters in the order you find them written, and reading off the number square gives you these numbers:

  • i + r = 5
  • i + a = 8
  • t + a = 7
  • s + o = 3

That makes the Father and Son safe code in Indiana Jones 5873

Use the code to open up the safe and you'll find some info that fleshes out the story. Specifically a surveillance photo of Indy meeting Father Antonio and at the Siwa dig where he found the Cat Mummy, a note about the surveillance, and another note referencing the Holy Grail. You'll also get 100 Adventure Points.

If you're wondering what else to play after this then take a look at the best new games coming out in the coming months.
