1. The person manipulating the visuals on the projector is the conductor (PEAK), and begins with 6 cards (two for each color).
2. All the players (SLOPE) start off facing the PEAK, their backs turned away from the projector (GROUND ZERO).
3. The conductor starts the game by giving the first card to the first player.
4. This player, as those that will follow, has to turn around and face GROUND ZERO, playing in the time indicated by his given color. After more cards are distributed and the first player leads the rest into the Avalanche, the following rules apply:
5. No player may play until assigned a card from PEAK.
6. When a player is given a card of the same color of someone facing GROUND ZERO, he trades places with the given person, assuming his position facing GROUND ZERO while the other turns around, returning his card to PEAK.
7. If the conductor hands out a folded card to a musician, he does not replace the musician of the same color, but instead compliments him, playing in the same time signature.
8. As the game progresses through different phases where there is first a minimum of 4 cards at the peak, then 3, then 2, then 1... the game ends after all cards arrive (half folded, half unfolded) at the SLOPE.
