About La Liga Sombra

La Liga Sombra (“The Shadow League”) is a browser-based educational detective game designed for high school Spanish 1 students. Students play as agents traveling through 10 Spanish-speaking countries, solving cases while learning vocabulary and grammar from the Que Chevere Level 1 curriculum.

The game is played in class on Chromebooks and takes approximately 30 minutes per unit (one class period). No downloads or accounts are required — students join using a 6-character class code provided by their teacher.
