Before playing Psychic Waves on any opponent’s bunny in The Bunny Circle, the player must secretly write down one of the six Symbols (Triangle, Rectangle, Spiral, Ellipse, Star or Cross) on a piece of paper hidden from all of the other players.
The opponent whose bunny was targeted by Psychic Waves will try to guess the Symbol chosen by the player. If the opponent guesses the incorrect Symbol, then his bunny dies. Clover bunnies (bunnies with Clover cards underneath them) may survive since Clovers lower the level of an attacking weapon.
Psychic Waves is then placed on the next bunny clockwise in The Bunny Circle and the process is repeated. This continues up to five times, or until the correct Symbol is guessed. Obviously as Psychic Waves continues, it becomes easier to guess the Symbol with fewer choices.
Psychic Waves is played during one player’s turn, and no Barrier can stop Psychic Waves.
