Impossible Quest: 14th Shadow Ending Guide

Full explanation and strategy to solve the last game in the game


Game mechanics

  • basically the game consists of 55 fields aranged in 5 rows and 11 columns
  • each field can have one of 2 states (black=inactive / white=active)
  • clicking on a field changes its state and also changes the state of up to 2 adjacent fields
  • the changed fields are always in the same row or column
  • the goal of the game is to activate all fields
  • the whole game can be solved on a sheet of paper
  • for the solution a single field is clicked once or never


first step:

  • draw the grid with at least 0.5” or 15mm edge length per field
  • click each field in the game and mark the direction of changing cells on the sheet

my preference: vertical or horizontal line in the cell

second step:

  • mark on each active field that it’s active (remember that the state will change)

my preference: a tally on the bottom right corner of the field
(empty = inactive; | = active; || = inactive; ||| = active)

third step:

  • a field could be switched by 5 fields (self + 4 adjacent)
  • it’s not neccessary but comfortable to mark how many fields still can switch a field
  • because the switches decrease during the solution, better mark how many adjacent fields can not switch a field; it’s easier to add a stroke on a drawing than remove it
  • fields on the grid edge have at least 1 irrelevant switch (no field outside of the grid)
  • fields in the grid corners already have 2 irrelevant switches
  • any adjacent field with a (green) line not pointing to the current field is also irrelevant
  • a field that is already set as pressed or not pressed is also irrelevant

my preference: a tally on the top left corner of the field


General Rules:

  • in each step choose one field to click or not to click (set click indicator = CL)
  • the chosen field and the adjacent fields (in direction) get 1 to switch indicator = SW
  • if a field is set as clicked, this field and the adjacent fields (in direction) get 1 to activity = AC

Here is a small example to explain the rules

Rule 1:

  • a field with SW4 that is not active must be clicked (field 1 in initial image)
  • a field with SW4 that is active must not be clicked (field 2 in step 1)

Rule 2:

  • 2 fields pointing each other with SW3 each must have the same activity state
  • if 2 fields pointing each other with SW2 and SW3; the field with SW2 can be raised from another field
    step 2 to 3:
    – field 4 & 5 pointing each other
    – field 7 can raise field 4
    – field 7 must be clicked to set state of field 4 & 5 equal
    step 3 to 4:
    – field 8 & 9 pointing each other
    – field 6 can raise field 9
    – field 7 must not be clicked to keep state of field 8 & 9 equal

Rule 3:

  • a field with SW4 that has a CL forces one adjacent cell to get a CL
    step 4 to 5:
    – field 7 has SW4 and CL but is not acive (AC2)
    – field 8 is pointing at field 7 and must be clicked

changes drawn in bold black; in this small example all fields are solved directly


  • the 3 rules above usually can solve at least the half game
  • possibly there will be some fields that can not be solved with the rules
  • every field without CL now should have SW3
  • set one random CL and solve further with the rules
    – start with clicked or not clicked does not matter; the result just flips

At this point chose any field with random CL
