Yes. Wavelength 4 players works very well when you set up two teams of two. One player on the active team becomes the Psychic, gives one clue, and their teammate places the needle after thinking out loud. Then the other pair takes a turn. With only four people, everyone gets enough time to talk, but the game still has the core team-reading tension that makes Wavelength fun.
The best default format is 2v2 competitive play. It keeps the table balanced, gives each player a partner to discuss with, and prevents one confident person from controlling every guess. If your group wants a calmer night, you can also play four-player co-op: all four players try to reach a shared score target over 8-10 rounds.
This page is intentionally about the four-player setup. For the complete rules, scoring zones, and general strategy, use the How to Play Wavelength guide. If you only have one person, use the single player Wavelength guide. If you need more spectra for your four-player game, open the Wavelength prompts list.
