===Simple spaces===
This method consists of determining spaces by searching for cells that are out of range of any possible blocks of boxes. For example, considering a row of ten cells with boxes in the fourth and ninth cell and with clues of ''3'' and ''1'', the block bound to the clue ''3'' will spread through the fourth cell and clue ''1'' will be at the ninth cell.

First, the clue ''1'' is complete and there will be a space at each side of the bound block.

Second, the clue ''3'' can only spread somewhere between the second cell and the sixth cell, because it always has to include the fourth cell; however, this may leave cells that may not be boxes in any case, i.e. the first and the seventh.

Note: In this example all blocks are accounted for; this is not always the case. The player must be careful for there may be clues or blocks that are not bound to each other yet.
