3. Candidates

4. A4=6h, B4=7h

5. G4=5s, H8=5c

6. G5=6h, G2=7s, G1=8s A-E5 must be 1..5, because A5 and C5 areatmost 5, so therangecannotbe 5..9 (anyotherrange, e.g. 3..7 isimpossiblebecauseof G5=46)

7. J5=7c, H5=8s

8. J1=6s, H1=7c, J6=8s, H6=9c

9. H2=6s, J2=5c, J3=4s, H3=3c

10. A3=5s, B3=6s

11. B8=8s, B9=9s, B7=5s

12. C7=6c, C8=7s, D8=6s, C9=8s, D9=7s

13. E6=6s, E5=5s, D4=3p

14. C5=4c, C6=5c, A5=3s, A6=4s

15. D6=2s, D5=1s, B6=3s, B5=2s

16. D2=4s, D1=5s, B2=1s, B1=4s

17. C1=3c, C2=2c, E2=3s

18. E7=1s, E3=2s, F3=1s, F4=2s, H4=1s

19. H7=4s, H9=2s, F7=3s

20. F8=4s, G8=3s, G9=1s Done

21. Variation: nohintat A7

22. Variation: nohintat A7 On the str8ts.de forum, Ulrich proposed a moredifficultvariation:nohintat A7

23. H8=5c, J8=8h, H8=9c, J5=7c

24. G5=6c, G4=5c, H6=8s

25. G2=7h, G1=8c, J1=6c, H1=7s

26. J2=5c, H2=6c, J3=4s, H3=3c

27. D4=3sD..H4, E6=6sE2..7 Candidate removal:C79:-9, because C56 is 5 at most / C56:-12 because C789 is at least 5analogue for A34

28. X-Wing on 4 X-Wing on 4 in rows A and C (markedgreen) removes all 4s marked orange

29. D6=2d, D5=1d, D2=4s, D1=5s d … strandeddigit
