Stop the Groans.Start the Climb.
Turn review day into the session students beg for. Multiplayer trivia games with real-time mastery tracking—built for K-12 teachers who need engagement without the busywork.
What Is Avalanche?
Avalanche transforms review into a multiplayer race up a virtual mountain. Students answer questions on their devices—correct answers move them higher, mistakes trigger avalanches and rescue challenges. You control the pace, award power-ups, and export mastery data when the game ends.
Real-Time Mastery Tracking
See exactly which students need help—while they're still in the room. Export results to your gradebook in one click.
Adaptive Difficulty
Questions auto-adjust to each student's level. High achievers stay challenged. Struggling students build confidence. Everyone stays engaged.
Built for Your Classroom
Hybrid? Remote? In-person? Avalanche works on any device without downloads or student accounts. Share your screen or let students play independently.
