The Indiana Jones Game of Wits safe code puzzle involves learning the Mak-Yek board game to complete Lorenzo’s challenge. This version of checkers or draughts gets you a four-digit code once completed and, while it has some simple rules, putting them into action to get the combination complicates things. Especially since you can’t move the pieces yourself to test possible solutions. Although don’t give up on getting into this safe in Voss’ base as it contains a lot of cash that you’ll almost certainly need, so I’ve explained how you get the safe code for the Mak-Yek board game puzzle below.

It's also a good idea to grab the Indiana Jones Royal Army uniform while you’re in Voss’ base as this’ll make sneaking around much easier.

Lorenzo’s challenge, which kicks off the A Game of Wits mystery in Indiana Jones and the Great Circle, tasks you with capturing all the red tokens by moving four different blue tokens only once each.

The rules sheet next to the board explains that pieces can move horizontally or vertically any distance until they hit a board edge or another piece. Additionally, enemy pieces are captured when they are surrounded on opposite sides by your pieces or you fill a one-square gap between two enemy pieces. The other key thing to bear in mind, which isn’t explicitly stated, is that captured pieces are removed from the board. That means you must imagine the red tokens disappear when captured, freeing up nearby blue tokens, which is crucial to getting the order of the code numbers correct.
