## What is GNIS?

GNIS. Sing it forwards. Hear it backwards. Sing it backwards. Reveal it forwards.

The most chaotic party game on your phone, filled with unexpected sounds, laugh-out-loud moments, and the occasional shockingly accurate performance.

HOW IT WORKS
Player A records a secret song. Player B hears it IN REVERSE and mimics the gibberish as closely as possible. When it’s flipped forward again, the original song might just reappear. If it does, you win! If it doesn’t… that’s a note-able failure.

Every round is a new experiment in music, memory, and terrible imitation!

MODES
Classic - 2 players. No scores. Just vibes and vocal destruction.
VS Battle - Go head-to-head over 3, 5, 7, or 10 rounds.

Zero ads. Zero data collected. Zero subscriptions. Pay once, play forever.

Think you can nail it?
