In all versions of Celestialis™ you will start at one star of your choice and draw to reach the other, your ending point if you will. Unlike most puzzles, however, the choice as to which should be the start and which the end is always up to you. [Note: Lefties may find selecting the lower most left star to their liking.]

(A) Traveling:
• You must draw along the X and Y axis only, no Z axis. In other words, you may only draw up or down and left and right--diagonal lines, generally, are not allowed.
• You may start by drawing from a star in any X or Y direction of your choice: up, down, left, or right. If you are a perfectionist, you may use a ruler or other straight edge to draw your line segments.
• The line segments you draw can be as long or as short as you like, but they should be as straight as possible -- which, technically, is the definition of a line segment -- and in the X or Y axes only.

(B) Switching Directions:
• When you are ready to switch directions, which is the key to earning points in a puzzle, you must follow a precise protocol outlined graphically in figure 1.
• So, when you are traveling in any one particular direction, there will be only two directions you can turn according to this protocol:

...when traveling from left to right, you can change directions up or down by looping (making a box) that takes you around and up or around and down...

...when traveling from right to left, you can change directions up or down by looping (making a box) that takes you around and up or around and down...

...when traveling from up to down, you can change directions right or left by looping (making a box) that takes you around and right or around and left...

...when traveling from down to up, you can change directions right or left by looping (making a box) that takes you around and right or around and left...

An example of a complete, legal drawing pathway is illustrated in figure 2.


(C) Size of the Loops:
• You should try to make your loops approximately the same size as about half the size of the stars as you can (within human limitations of course). A general rule to follow is that the two line segments needed to make the turn MUST be of equal length, while the segment that actually results from the two that cause the change in direction can be of any length. And, likewise, therefore, all of the direction changing segments should be of equal length in your entire puzzle.

(D) Crossing Over, Loops & Lines, Out of Bounds:
• You may cross over single lines but you may not pass through loops.
• Loops may not touch.
• Lines may not overlap and you may not go out of bounds or off the course.
