Creating GraphiLogic puzzles

Creating puzzles is easy. Open a puzzle with 'Edit', or create a new one from the game menu, tap the screen to draw and click back to save the puzzle.
But creating puzzles which are really fun to solve requires some care and a bit of practice.

At first, it seems easier to draw something on a larger table, but in fact, sometimes it's just the opposite:
drawing something in low resolution will trigger the viewers' brain to fill in the details from their own memories and imagination, thus creating a final image matching their personal taste.
Also, most of the people will happily solve 10x10 or 15x10 puzzles anytime, but will postpone 25x20 or bigger ones to "later".
Usually it's a good practice to try drawing in small (e.g. 10x10), and increase the size if the drawing couldn't fit.

GraphiLogic provides an "image overlay" function: in edit mode you can load an image to use as a template. You might want to crop the image with your picture viewer/editor application previously to optimize the table area. Once the image is overlaid, you simply fill it, or draw its contours. As the resolution of the table is significantly lower than that of the images, you will need to optimize the drawing.
A cell mostly filled with a color on the overlay will be set to the corresponding color on the table. Once the basic drawing is done, you can fine-tune it by changing individual cells one-by-one.
Low color count images (like a color GraphiLogic puzzle) can really benefit from dithering (drawing a pattern from different colors, thus mixing them), but use this technique carefully: Solving a puzzle with excessive dithering causes a lot of 1- or 2-dot blocks, which might tune down solving experience.

Be careful with color puzzles: when defining the palette colors, GraphiLogic will note if colors are getting similar to each others, and warns you when colors are getting indistinguishable. When you see red circles on the palette editor, and/or getting a message box with a red exclamation mark while leaving the palette editor screen, please consider modifying your colors. If you build your puzzle using two or more similar colors, solving them could become frustrating (as there is a high chance of marking a cell with the wrong color), or even impossible.

If you're creating mosaic puzzles, there is a number of possible rule definitions for a single drawing. The application will auto-generate a rule set (when activated from the options menu), to make the table solvable. But you can tune the difficulty of the puzzle by adding number to some of the cells, or removing from others.

Drawing impossible puzzles makes no point, thus GraphiLogic will not let you share an impossible one (a puzzle containing cells marked with red question mark in edit mode). But drawing very hard puzzles (cells marked with a red 'H' in edit mode) are another story. It's not for beginners, nor for most of the experienced users. Only the most enthusiastic users will love them, solving a 15x15 one could take up hours. It's really about stressing your brain. There is only one advice: if you create one, test it: solve it yourself before sharing.
