This game is won by thinking in terms of Integration Theory:


  1. 1. Playing Phrygian cards activates the keys (columns).
  2. 2. Once a Phrygian card’s note has been played, it can be played in its other 6 keys.
  3. 3. Win the game by playing all the cards!

– Play in Easy Mode to help you understand the game mechanics. Play in Hard Mode to put your Integration skills to the test!


When you win, you get a summary of your game:


  1. The Keys: As you play Phrygian cards, a unique sequence of keys is made from left to right.
  2. The Melody: The sequence of Phrygian notes.
  3. The Harmony (Squared): The first non-Phrygian card played (face down) in each key.

Each game is played with a shuffled deck of 84 cards, so every time you win, the game ‘writes’ you a unique song using Integration Theory!
