Flag - Games

In game design, flags are binary triggers that track player progress and unlock content. They mark quest completion, track discovered locations, and trigger branching narrative paths. Flags create dynamic worlds where player choices have tangible consequences—opening new areas, altering NPC dialogue, or changing faction relationships. This invisible scaffolding enables non-linear storytelling and personalized gameplay experiences. From simple checkpoints to complex state machines, flags are the fundamental building blocks of interactive progression systems.
