An Easy 6×6 Puzzle Solved with Shape Squeeze in 9 Steps

This 6×6 board rates as easy (difficulty score 752). Solving it from scratch takes 9 logical steps, using 5 techniques: Single cell, Row/column exclusion, Adjacency clear, Region confinement, Shape squeeze. Every step below is forced: nothing here is a guess.

1. First, every open cell left in this region sits in row 1, so its marker has to land there; that clears every other open cell in the row.
2. Next, place a marker at B2. Region has exactly one open cell left. Placing here clears the rest of row 2, column B, and its region. Placing here also clears its 3 touching neighbours.
3. Then, place a marker at A4. Region has exactly one open cell left. Placing here clears the rest of row 4, column A, and its region.
4. After that, place a marker at F3. Region has exactly one open cell left. Placing here clears the rest of row 3, column F, and its region.
5. Now, every open cell left in this region sits in row 6, so its marker has to land there; that clears every other open cell in the row.
6. From there, every remaining candidate in this region touches D6, so whichever candidate ends up marked will clear it, and it can be ruled out now regardless of which one wins.
7. Following that, place a marker at C6. Region has exactly one open cell left. Placing here clears the rest of row 6, column C, and its region. Placing here also clears its 1 touching neighbour.
8. First, place a marker at E5. Region has exactly one open cell left. Placing here clears the rest of row 5, column E, and its region.
9. Finally, place a marker at D1. Region has exactly one open cell left.

The key move here was Shape squeeze. Once you can spot that, this board falls quickly. ∎
