Three tables in three rows
The same idea as two tables in two rows, one size up: when three tables together fit inside three rows, the cups of those rows are in those tables, and everything else in the three rows gets an X.

How to spot it
- It shows up on bigger boards, from 7 by 7, often along an edge.
- Count: how many tables have all their free spots inside these three rows? If the answer is three, you have it.
- Work it the other way too: three rows whose free spots all belong to three tables.
Why it works
Three tables need three cups, and all their free spots are inside three rows. Three rows hold exactly three cups, so those cups are the tables’ cups. No other spot in those rows can have one.
Try it on a real board
Play a free board in your browser, no account needed. When you are stuck, the hint shows where to look, then explains the step.
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.
