## Simon Selects Binary Again

"I smile back, knowing that I can tell this to my grandkid."

On the module, there are ten buttons: eight of them colored red, orange, yellow, green, cyan, blue, purple and magenta, a center button, and a mute button. Random colors will flash, and every stage, another set of flashes will be added. There are three stages. For stages 2 and 3, only consider the flashes that were added to the sequence when determining what to modify to your last stage's answer. Each stage can flash the same color more than once.

To solve the module, press the correct set of buttons based on the flashes for each stage, then press the center button to submit the set for each stage.

Two of these... | Makes 1 of this. |
---|---|

2x Red | 1x Orange |

2x Orange | 1x Yellow |

2x Yellow | 1x Green |

2x Green | 1x Cyan |

2x Cyan | 1x Blue |

2x Blue | 1x Purple |

2x Purple | 1x Magenta |

2x Magenta | 1x None |

Color | Position in Binary |
---|---|

Red | 2^{0} (smallest) |

Orange | 2^{1} |

Yellow | 2^{2} |

Green | 2^{3} |

Cyan | 2^{4} |

Blue | 2^{5} |

Purple | 2^{6} |

Magenta | 2^{7} (largest) |

You can press a button after it has been selected to deselect it. Selecting a button makes a sound but deselecting does not. The mute button when pressed will restart the color sequence, but also mute all sounds until another press is made.

Simplify your flashes to get your current set for this stage, using the table on the left. Those will be referred to as "lit bits" for the next step.

Once you got the current set, start with the smallest "lit bit" in that set. The smallest "lit bit" is the top-most row on the table to the right that is lit on the module. **If there are no "lit bits," press red, then the submit button, and then remember that set for the next stage.** Otherwise, if the smallest "lit bit" is not magenta, go to the next bit and toggle that bit. The next bit in the set is the next row on the table to the right of this page. Toggle the next bit down the table until you have toggled magenta. That will be the starting set for the next stage if the set you submit is correct.

On the next 2 stages, use the set you got on the previous stage and modify your current set by repeating the 2 steps from above.
