While many gamers resort to online guides for puzzle solutions, Indiana Jones and the Great Circle offers a surprisingly effective in-game hint system that's more convenient than Google.
The hint system is accessed through Indy's in-game camera, unlocked early in the Vatican area. Besides providing hints, the camera is used for quest objectives and earning bonus XP by photographing points of interest.
Simply point the camera at a troublesome puzzle and snap a picture. A hint will appear in the upper-left corner of the screen. These hints persist until the puzzle is solved, acting as a helpful log.
The hints escalate in specificity with each photo taken. Initial hints offer gentle nudges, while subsequent ones provide more direct instructions. If you're truly stuck, the game will eventually give you the complete solution.
So, before rushing to Google for help, try the in-game camera. It's a faster, more immersive way to get unstuck without breaking the flow of the game.
