An Easy 7×7 Puzzle Solved with Shape Squeeze in 11 Steps

This 7×7 board rates as easy (difficulty score 763). Solving it from scratch takes 11 logical steps, using 6 techniques: Single cell, Row/column exclusion, Adjacency clear, Region confinement, Line confinement, Shape squeeze. Every step below is forced: nothing here is a guess.

1. First, every open cell in column G belongs to the same region, so that region's marker has to be somewhere in this column; that clears every other open cell in the region.
2. Next, place a marker at F1. Column 6 has exactly one open cell left. Placing here clears the rest of row 1, column F, and its region. Placing here also clears its 1 touching neighbour.
3. Then, place a marker at E4. Column 5 has exactly one open cell left. Placing here clears the rest of row 4, column E, and its region.
4. After that, place a marker at D2. Column 4 has exactly one open cell left. Placing here clears the rest of row 2, column D, and its region.
5. Now, every open cell left in this region sits in column A, so its marker has to land there; that clears every other open cell in the column.
6. From there, every open cell left in this region sits in row 7, so its marker has to land there; that clears every other open cell in the row.
7. Following that, every remaining candidate in this region touches B6 and C6, so whichever candidate ends up marked will clear them, and they can be ruled out now regardless of which one wins.
8. First, place a marker at B5. Region has exactly one open cell left. Placing here clears the rest of row 5, column B, and its region.
9. Next, place a marker at A3. Region has exactly one open cell left. Placing here clears the rest of row 3, column A, and its region.
10. Then, place a marker at G6. Region has exactly one open cell left.
11. Finally, place a marker at C7. Region has exactly one open cell left.

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