I have 9 boxes, each with 1.5cm height and width. I want to place these boxes in a grid (for the sake of simpleness, let's put them in a 3x3 grid). The total size that my grid can hold up is around 7x7 cm.

Then, I would need to connect some of these boxes in the grid, in a way, where direction matters.

For example, if I get the following grid:


I would for example need to connect the box with id 6 to the box with id 3 and 5, representing that you can travel from 6 to 3 and 5 but not inversely(you can not travel from 3 to 6 and neither from 5 to 6).

My connections will always have to be one directional, so there can be no connection between 6 and 5 if there is already a connection from 5 to 6.

I hope that I didn't overcomplicate my question, and it is understandable:) I would prefer a solution which uses the white space between the boxes in the grid (I know that the alloted space is rather small), because there will be icons in each four corners of the boxes.

These boxes would be put on a card for a physical board game, so the end result should be visible when printed.

Anyone has any ideas on this?

  • It's been 4 years, have you found a solution for this? I stumbled upon this question and it made me curious. Maybe you could post an answer yourself?

What have you tried? Arrows are pretty universal.Given the lack of space, use arrow heads. Another idea is to use doorways similar to a house plan, but showing that one can only go through the doorways in a certain direction. You could provide complementary instructions on the game to help avoid ambiguity when reading the card.

    I am not home at the moment, but I could upload some pictures on what I've tried so far, later today. Basically, the spacing between two boxes are so small, that a standard arrow, or even an arrow head, gets lost in translation. It is simply not visible, if you do not lean over the card, and examine it very very closely. I also tried putting in an arrow, in the middle of the box, but this just takes up too much space from the box, which is overcrowded even as is at the moment with icons in the four corners.
