There are three main game modes in Crossroads Inn.
- Sandbox Mode: The player is free to build their own tavern and create their own narrative, at their own pace and at their desired difficulty level.
- Campaign Mode: "From an Innkeeper to a King". The player is guided by the overarching story, and must make decisions and complete tasks that influence and develop the narrative. The campaign is divided into the Prologue, designed as a tutorial for the player, and three acts.
- Scenario Mode (early access): The player adopts an existing inn, and is required to complete a range of time-sensitive objectives to solve the scenario. This mode was previously known as "Scripts" Mode during game development.
It is recommended that new players complete the Campaign Prologue to obtain a basic overview of game mechanics and controls.
