Gira Trilhos is a quick two-player puzzle game where each player tries to build a valid rail path connecting their train to a shared station. Twelve track cards are shuffled and arranged face-down in a 3×4 grid, with a station card placed at the bottom center.
On their turn, a player chooses one of three actions: flip a face-down card at the end of their current path to reveal its track, rotate an already revealed track card along their path to change its direction, or move their train to a different column. Players alternate turns, gradually uncovering and adjusting track segments to form a continuous route. The first player to complete a valid path from their train to the station earns a reward token, after which the grid is reshuffled for a new round. The game ends when a player collects three reward tokens.
