On the Subject of U

A single letter creative module? Has this happened before?

This module initially consists of the letter U on the module.

When the timer ticks, the letter U will change colors based on the logic gate applied to the last 4 binary digits of the hidden value from 0 - 15 with the last 4 binary digits of the seconds timer, in that order, with exactly one the following cases applied to the seconds timer:

  • 1 is added to the seconds timer displayed, before/after modulo 15.
  • The seconds timer displayed, modulo 15.
  • The seconds timer displayed, modulo 15, with 0 being treated as 15.

If multiple Us are present, they will be paired together*. Logic gates that were not used in one will be used in the other, and vice versa. Modules paired have a colored square above the letter denoting where it is paired to, which can be selected to confirm the pair.

The colors displayed on U evaluate to the resulting binary digits via their channels, in the form RGBV, in that specific order, with V corresponding to the least significant bit. To disarm the module, press the letter when the seconds timer, modulo 15, is the hidden value. If the hidden value is 15, submit it on 0, modulo 15, instead.

One of the logic gates can always be determined across each U module which have 4 distinct gates. Depending on the amount of 90° rotations clockwise from the module, initially with the status light in the top-right, this will determine the position of the logic gate that can be determined, 0-indexed and ticking up from the countdown timer. The letter is NEVER rotated.

Hovering the U will change the background color of the module to a different color. If the background color did not change, it is white. This color determines the logic gate in that position, using the first table on the next page.

If colorblind mode is enabled, four squares will be displayed underneath the letter. These correspond to the RGBV values in that order, where the color being present denoting 1, and 0 otherwise. When hovering the letter, the last square will disappear until the letter is no longer hovered over, which is used to reference the color the backing changed into.
