On the Subject of Miscommunicated Black Arrows

Point this away from being a boss module. Point it such that a boss arrows module would never exist.

If the arrows are not black, the arrows are flashing directions, or the display is empty, you are looking at a different module.

To disarm this module, navigate through a blind maze filled with 40 trapped tiles, to find the escape tile. Start with concatenating the 3rd and 6th characters of the serial number as the first number and the displayed number as the second. Do this every time upon taking a strike on this module.

Take the number of ports on the bomb, modulo 6, and add 1 to this. Count this many items in the list provided on the next page and assign this to the first number to obtain a position. Assign the next item underneath, wrapping around to the top if necessary, to the second number to obtain another position.

Take the horizontal and vertical distances between those two positions, for each of the four directions. Press the direction such that, when accounting for wrap-around, the user travels 1 step closer to the second position from the first position, by narrowing the maximum orthogonal distance. Do not try to stray away from that direction.

After enough presses, a new two-digit number will show. Using the next item in the list from the item used for the last number displayed, wrapping around to the top if necessary, apply the procedure above to your current position and the new number, repeating until navigating to the escape tile.

Navigating to a trapped tile will result in a strike, teleport the user back to the initial position, and reset the module with new trapped and escape tiles.

The two digit number is referred to AB on the list provided.

  • A as row, B as column
  • AB on the table
  • B matches last digit of values in A’s column
  • A as column, B as row
  • BA on the table
  • B matches first digit of values in A’s row

There is a good reason why a 10:2 Latin Square takes so long with standard brute force. Basically every single application cannot generate it.
