Introduction:
“This is a progressive puzzle which you can comfortably enjoy working out using logic. “Heyawake” is a puzzle in which you fill in the spaces according to the rules. It's called “heyawake” (“split rooms”) because the face of the board is divided into rooms. This puzzle first appeared in 1992, but a plethora of solutions have been developed, allowing for a very progressive puzzle. Each time you discover a new strategic move, your skills of solution will improve.” - xbox.com

Heyawake is played on a rectangular grid of cells with no standard size; the grid is divided into variously sized rectangular “rooms” by bold lines following the edges of the cells. Some rooms may contain a single number, typically printed in their upper-left cell; as originally designed, every room was numbered, but this is rarely necessary for solving and is no longer followed.

Some of the cells in the puzzle are to be painted black; the object of the puzzle is to determine for each cell if it must be painted or must be left blank (remaining white). In practice, it is often easier to mark known “blank” cells in some way - for example, by placing a dot in the center of the cell.

The following rules determine which cells are which:
 
  • Rule 1: Painted cells may never be orthogonally connected (they may not share a side, although they can touch diagonally)
  • Rule 2: All white cells must be interconnected (form a single polyomino)
  • Rule 3: A number indicates exactly how many painted cells there must be in that particular room
  • Rule 4: A room which has no number may contain any number of painted cells, or none
  • Rule 5: Where a straight (orthogonal) line of connected white cells is formed, it must not contain cells from more than two rooms - in other words, any such line of white cells which connects three or more rooms is forbidden - wikipedia.com
The rules of this game sound confusing at first but once you understand them, it is rather quite simple. It is highly recommended that you read through the ‘How to Play’ information in the main menu if you want to learn how to play the game without a guide. It explains the rules in detail much better than here.

A YouTube PLAYLIST created by PuzzleTeam features videos that further explain the game in layman’s terms and offer videos from leading puzzle solvers that may be helpful as well.

If you want to practice your skills, the game is available to play online HERE.

There are 10 achievements with a total of 1000 points

  • Read to the last page of the guide.

    On the main menu, select ‘Game Start’. Next, select ‘How to play’ and when the next screen appears, use dpad-right.png to scroll through all 21 pages of the instructions. When the achievement unlocks, press button-b.png to return to the previous screen.
  • Total play time exceeds one hour.

    Time only accrues while you are in a puzzle, not on the menu. You will unlock this naturally while you are clearing all 50 puzzles.
  • Clear 1 board.

    Refer to Complete conqueror (100G) for more information.
  • Clear 5 boards.

    Refer to Complete conqueror (100G) for more information.
  • Clear 10 Boards.

    Refer to Complete conqueror (100G) for more information.
  • Clear 20 boards.

    Refer to Complete conqueror (100G) for more information.
  • Clear 30 boards.

    Refer to Complete conqueror (100G) for more information.
  • Clear 40 boards.

    Refer to Complete conqueror (100G) for more information.
  • Clear All Boards.

    Note: It is recommended that you work on Shuffle mania (100G) first so you don’t repeat puzzles unnecessarily.

    To earn this achievement, you need to clear all 50 puzzles in the game. The puzzles are broken up into three difficulties: Easy, Medium and Hard. You can attempt to clear all 50 puzzles on your own (as intended) or you can refer to the video below for all the answers.

    By doing Shuffle mania (100G) first, you should have cleared 8-12 puzzles. Navigating around a puzzle with analog-left.png might be cumbersome, but I found that using the D-pad was much easier.

    The video below has screenshots of all 50 puzzle solutions. Going one by one, each taking an average of 60 seconds to 4 minutes to complete, fill in the black squares as shown in the video and when you’ve finished that puzzle, click analog-left.png to check for mistakes. If everything is correct, you will get a congratulations message. If you happened to make a mistake, it will show you which squares need to be corrected. Correct anything needed and after the puzzle is cleared, press button-a.png to return to the menu.

    If you want to make another menu selection, press button-b.png. Otherwise, select another puzzle and repeat the process until all 50 puzzles have been cleared. Puzzles which have been cleared are identified with a gold ribbon.

    Thanks to The Hidden Levels for the video with assistance from Dwaggienite:
  • Shuffle clear 15 times.

    Note: It is recommended that you do this achievement first so you don’t repeat puzzles unnecessarily.

    On the main menu, select ‘Shuffle’. The game will randomly select one unlocked puzzle for you to solve. Once you’ve successfully cleared it, return to the main menu and select ‘Shuffle’ again and keep repeating until the achievement unlocks. For all puzzle solutions, refer to the video in Complete conqueror (100G).

    If you happen to get a puzzle you’ve already cleared, solving it again will still count towards the achievement (but not the clear # boards achievements).
