No guessing at all required - here, or for any of these puzzles: you just have to crunch the numbers, and correlate the rows in three different directions. Some of the correlations are extremely hard to find, though. However, once you see a pattern starting, you can often guess how it's likely to continue and fill it in; but there is always a risk you will be wrong, and so mess up the whole puzzle.

Took a lot of guessing to complete this puzzle. For starters, the symbol is upside down!

Ok, but too much guessing needed to solve these.
