1. (02) can only be placed in (2,1) or (1,2), since it has to be connected to (01). However, having (02) in (2,1) makes the puzzle unsolvable. Hence, (02) has to be placed in (1,2).

2. This implies that (03) must be placed in (1,3).

3. This implies that (04) must be placed in (2,3).

4. This implies that (05) must be placed in (3,3).

5. This implies that (06) must be placed in (3,2).

6. This implies that (07) must be placed in (2,2).

7. This implies that (08) must be placed in (2,1).

8. This implies that (09) must be placed in (3,1).
