Trailblazers are the courageous people who pave and brave the paths of the great outside world. Whether it's with hiking boots, bike wheels or paddles on the river, these determined travelers strive to feed their insatiable thirst for adventure. With a picturesque wilderness always before them and a freshly mapped route at their heels, one must not forget to eventually find their way back to camp. There are always new environments to explore, further expeditions to undertake and more paths to pave.

In Trailblazers, players compete to earn the most points by building biking, hiking, and kayaking trails from their campsites of the corresponding trail type. Each round, players are dealt eight trail cards, from which they choose two cards, arrange them in their personal area, and then pass them to the next player three times. Cards must be placed next to or overlapping with other cards. Although players can try their luck by attempting to construct long and complicated paths, only closed loops that start and end at a corresponding campsite score points. Players also compete to fulfill "First" and "End of Game" goal cards. After four rounds, the game ends and the player with the most points from closed routes and goal cards wins.
