Two tables in two rows
When two tables together fit inside two rows, those two rows are already spoken for: their two cups are in those two tables. Every other spot in the two rows gets an X. Columns work the same way.

How to spot it
- Look for two small tables that sit next to each other in the same band of two rows or two columns.
- Check that every free spot of both tables is inside those two lines. One spot outside and the step does not work.
- It also works the other way around: two rows whose free spots all lie in two tables.
Why it works
The two tables need two cups, and all their free spots are in two rows. So both cups land in those rows. Two rows hold exactly two cups, so the rest of both rows has no room for another one.

The Brewdoku app has 300 levels that bring in these steps one at a time, from small boards to 10x10, and a hint that shows where to look, then why, and only then makes the move.
