The Reverse Singing Challenge: Rules & How to Play It
The Reverse Singing Challenge is a viral game where you listen to a song played backwards, imitate the reversed sounds, then flip your recording to hear how close it is to the real lyrics. SupaFlip — subtitled "Reverse Singing Challenge" on the App Store — was built exactly for this.
How the challenge works
- Pick a line. Choose a short, well-known lyric or phrase — one line works better than a whole chorus.
- Hear it backwards. Record yourself singing it normally in SupaFlip's Audio Mode, then tap Reversed and listen carefully. Slow playback to 0.25x to catch each backwards syllable.
- Imitate the reversed version. Now record a new clip where you sing those strange backwards sounds as accurately as you can.
- Flip it back. Reverse your imitation. If you did well, the original lyric emerges — usually with a hilarious accent.
- Challenge friends. Share only the reversed clip and let friends guess the song, or let them un-reverse it with Decode Mode.
Tips to win the reverse singing challenge
- Start short. Two to four words. "Happy birthday to you" is a classic starter.
- Use speed control. Learning the reversed audio at 0.25x, then performing at full speed, is the single biggest accuracy boost.
- Exaggerate the weird sounds. Backwards English is full of inhaled consonants — lean into them.
- Play in teams. One team records, the other guesses the song from the reversed clip alone.
