Hi goooders,

You've got the bracketing wrong here. Here's how it should be entered to get the "solution is..." part in tiny text (TT):

Code:
just testing

[size=1]solution is......[/size]


Note: The "size=7" tag generated by the "Font size" combo box for "Tiny" font size is still a bit too big, so I would recommend overtyping the 7 with a smaller value (e.g., 1 or 2), as shown above. To be quite honest, I don't use this combo box at all, and just type in the tags manually.

Tip: If you're not sure how something is done, just pick any post from someone else containing the desired formatting feature and press the quote button next to it. This will reveal the formatting tags they used to get the observed effects.

Hi all

That was fun. Just being a bit creative on this one. Didn't really take the more conventional opening. Was having some fun with this one. Also used a technique we don't get to use much in Assassins. Guess this assassin rates somewhere between 1.00 and 1.25.

Walk-Through Assassin 64

Hmm - more a 1.5 in my book - quite a challenge. Contrary to Ruud's comment on the puzzle page, I thought the 45(9) cage was quite helpful for some later eliminations. Key move at step 29 - is there a particular name for this?

Edit: Answering my own question! Having gone through this using JSudoku, my step 29 is apparently an xy-loop.

Further edit - see note after step 17.

Here's my WT - a bit longer than Para's!

Prelims:

a) 8(3) N1 = {125/134} 1 not elsewhere in N1
b) 30(4) r3c12+r4c23 = {6789}
c) 13(2) N1 = {49/58/67}
d) 27(4) N2 = {3789/4689/5679} 9 not elsewhere in N2
e) 7(2) N2 = {16/25/34}
f) 6(2) N3 = {15/24}
g) 13(4) r6c78+r7c89 = {1237/1246/1345} must have 1
h) 23(3) N9 = {689} not elsewhere in N9 -> 10(2) N9 = {37} not elsewhere in N9/c9
-> r7c89+r9c78 = {1245}
-> 14(3) r9c678 = {149/248/158/257} -> r9c6 = (789)
i) 8(2) N7 = {17/26/35}
j) 11(3) r456c1 and r5c678: no 9
k) 20(3) N7: no 1 or 2

1. Innies c1: r37c1 = 13 = [67/76/85/94]: r7c1 = (4567) -> 9 locked r123c1, not elsewhere in N1

2. Innies c9: r37c9 = 10 = [91/82/64] -> r7c9 <> 5
-> 19(3) r456c9 = {289/469/568}

Edit: Andrew noted I could also have had r1c5 <> 9 here

4. Innies r5: r5c159 = 19 (no 1) = {289/379/469/478/568}

5. Innies r9: r9c159 = 18 = [693/783/297/387/567/657]
-> r9c1 <> 1 -> r8c1 <> 7
-> r9c5 = (5689)

6. Innies N2: r1c46 + r3c5 = 11 = {128/137/146/236/245}

7. Innies N8: r9c46 + r7c5 = 13

-> r9c4 + r7c5 = (1…5)

8. Outies N1: r1c4 + r4c23 = 20 = {677/686/695/785/794/893}
-> r1c4 = (34567)

9. Outies N3: r1c6 + r4c78 = 13

10. Outies N7: r9c4 + r6c23 = 10 = [127/136/145/217/226/235/316/325/334/415/424/514/523]
({118} blocked by r7c1 min 4) -> r6c23 <> 8

11. Outies N9: r6c78 + r9c6 = 15 = {17/26/35}7; {16/25/34}8; {15/24}9

12. Innies c1234: r2346c4 = 25 = {1789/2689/3589/3679/4579/4678}

13. Innies c6789: r4678c6 = 25 (same options as above!)
(Andrew noted that actually {1789} is not possible for this split cage)
14. Outies r12: r3c3467 = 17 -> r3c12589 = 28
Min from r3c129 is 21 {678} -> r3c58 is max 7 -> r3c58 = (1…6)

15. Outies r89: r7c3467 = 30 = {6789}
-> r8c4 = (123)
-> r7c1 = (45) -> r3c1 = (89)
-> pointing cells: r56c2 <> 6,7

16. Outies c123: r159c4 = 11
r1c4 min 3, r9c4 min 1 -> r5c4 max 7
r1c4 max 7, r9c4 max 5 -> r5c4 min 1
-> r5c4 = (1…7)

17. Outies c789: r159c6 = 13
r9c6 min 7 -> r15c6 max 6 -> r15c6 = (1…5) -> r1c78 = (4…9)
-> 27(4) N2 must have both 89 = {3789/4689}
-> split 11(3) N2 must have one of 3 or 4 {137/146/245} ({236} blocked by 27(4))
-> 7(2) N2 <> {34}

Edit: Evidently when I did this, I neglected to remove the 5s from the 27(4) cage which affects step 19 and leads to a naked quad in c1.
Sorry - I don't have the inclination to rework the rest of this WT!

Fairly straightforward singles and cage combinations from here
Very Happy

Here is a V2

JSudoku needs a lot of steps to solve this version.



3x3::k:2816:4353:4353:4353:5124:3845:3845:3845:3080:2816:4106:4106:5124:5124:2062:4367:4367:3080:3602:3602:4106:5124:11542:2062:4367:4121:4121:5147:3602:3602:11542:11542:11542:4121:4121:3107:5147:2341:2341:2341:11542:5673:5673:5673:3107:5147:5934:5934:11542:11542:11542:3891:3891:3107:5934:5934:2872:1593:11542:6459:4412:3891:3891:2367:2872:2872:1593:6459:6459:4412:4412:2887:2367:6217:6217:6217:6459:2637:2637:2637:2887:

According to Ed's rating list from Sudoku Solver given in the A61 thread, the V2 has a marginally lower rating than the V1 - 1.28 compared to 1.29 presumably indicating that it shouldn't be any more difficult. But I beg to differ - completely stumped after 26 steps. Confused

If anyone would like to play tag here's my steps so far. For now I'm going to stop Brick wall

A64V2

Prelims

a) 24(3) r9c234 = {789) not elsewhere in r9 -> r8c1 <> 1,2; r8c9 <> 2,3,4

e) 12(2) N3 = {39/48/57}
f) 20(3) r456c1 = {389/479/469/578} – no 1,2

At this stage I cannot see any useful locked candidates, pointing cells, killer pairs, normal fish (I've never quite understood the finned variety!), or even any eliminations from cage combinations.

Suggestions or next steps welcome.

Hi Cathy,

Thanks for starting this off.

CathyW wrote:
According to Ed's rating list from Sudoku Solver given in the A61 thread, the V2 has a marginally lower rating than the V1 - 1.28 compared to 1.29 presumably indicating that it shouldn't be any more difficult.

No question about it IMHO. This V2 is significantly harder than the V1. Just shows that there's some more tweaking for Ed to do before we can replace the manual ratings with the automatic ones. In particular, as I mentioned before, ratings typically do not consider one very important factor, namely the narrowness of the solving path. The V1 clearly had quite a wide solving path, otherwise Para would not have been able to have so much fun playing around with it. For this V2, the solution path is probably much narrower. It may be that it's not much more difficult in retrospect, once one has eventually stumbled across the critical move(s), but one has to spend ages finding 'em first! Even so, I cannot believe the V2's solving path is easier than the V1's.

On the other hand, here's some lateral thinking for you:

(i) The low (1.28) rating for this puzzle comes from SudokuSolver, right?
(ii) Computer programs take after their "masters" (i.e., programmers), right?

==> Ergo: Richard should find this V2 a breeze! Smile


However, whilst I'm at it, I can give you a few more moves to keep you going for a while:

Edit: incorporated Cathy's suggestions re:step 28 and updated marks pic.

Assassin V64 V2 Tag Walkthrough (continued)

27. Revisit step 14: {1789} combo blocked by r9c4
27a. -> no 1 in r9c5

28. Outies n6: r37c89+r5c6 = 20(5)
28a. from step 2: r37c9 = 10(2)
28b. -> r37c8+r5c6 = 10(3)
28c. -> no 8,9 in r5c6; r37c8 = {1234}
28d. Combos for split 10(3) r5c6+r37c8 = {127/136/145/235} (no repeated digits, thus can be treated as if all cells were peers of each other)


29. Revisit step 18: {237/156} both blocked by 8(2)n2; 8,9 no longer available
29a. -> 12/3 at r159c6 = {147/246/345}
29b. -> must have 2 of {1234}, only available in r19c6
29c. -> no 5,6 in r19c6
29d. 4 locked in r19c6 for c6

30. 9 of 22(3) locked in r5c78 for n6
30a. {89} only available in r5c78
30b. -> no 5 in r5c78

31. LoL(n5) (step 12): no 8,9 in r3c5

32. Revisit step 11: 10(3)r9 must contain 1 of {56}, only available within n9
32a. -> 11(2)n9 <> {56}

New marks pic after step 32a:

Excellent! Real progress there Mike. You deserve your Master status! Smile

I would add to your step 28: The combination options for the split 10(3) r5c6+ r37c8 are {145/235/136/127} -> r37c8 = (1234)

Hopefully will post more later - I've also been getting some suggestions from Howard S (a regular on the DJape forum who will shortly be joining us here!)

Thanks, Cathy. How could I miss that? Embarassed Maybe it's a hint fom above not to get too cocky just because of the new Master status?! Smile

I've modified my post (incl. marks pic) above to incorporate your addition.

I don't visit the DJApe forum very often, but when I do (every now and again) I see Howard's name everywhere! So it will be a real boost to have him on the team. Look forward to that.

A few more:

Acknowledging assistance of Howard S for steps 33 and 34

33. r7c12 = 8, 9 or 10 (because r7c12 + r9c23 = 25)
-> r6c23 = 13, 14, or 15
-> r45c23 = 10,11 or 12
-> r4c23 <> 7,8

34. Combination options for split 17(3) N2: {179/269/278/359/368/458/467}
Analysis: r1c4 <> 4,5, r3c5 <> 2,3,4

35. Outies N4: r37c2 + r5c4 = 16

36. Revisit step 6: r1c6 + r4c78 = 15 = {168/258/267/348/357/447/456}
Analysis: r4c78 <> 1,2
-> 1,2 locked to r45c9, r6c789 -> r7c9 <> 1,2 -> r3c9 <> 8,9

37. 15(3) r1c678: r1c6 is max 4 -> r1c78 min 11 -> r1c78 <> 1

38. Split 19(3) r159c4 = {289/379/469/478/568}
Analysis: r5c4 <> 6
-> (from step 35) max from r5c4+r7c2 = 5+9 = 14 -> r3c2 <> 1

39. 6 locked to r12346c4 -> r3c5 <> 6
-> split 17(3) N2 must now have one of 5,7. If combo includes 7 it must go in r3c5 -> r1c4 <> 7

40. split 17(4) r7c89+r9c78 = {1259/1268/1349/1358/1367/1457/2348/2357/2456}
Analysis: r7c9 <> 3 -> r3c9 <> 7

41. 9 locked to r3c347 within split 26(4) -> 26(4) r3c3467 = {9...}
Options: {2789/3689/4589/4679}
If {4589} r3c6 = 5 -> r3c347 <> 5

One small new piece of info

If R9C4=7 R6C23=15
If R9C4=8 R6C23=14
If R9C4=9 R6C23=13=> R7C12=46I19 => R6C23<>94
=> R6C23<>4

Might as well jump in for a couple of quick moves:

43. 45 on n3 - outies total 15.
43a. r4c78 max is 13 to fit with the 16(4) cage
43b. so cannot have 1 at r1c6

44. 45 on n9 - outies r6c78+r9c6 total 8.
44a. only possibility with 6 is {16}1 but {16} would block all possibilities in 12(3)n6
44b. so cannot have 6 at r6c78

45. 15(4)n69 - only combinations with a 4 also require an 8, 7 or 6 which only occur at r7c9
45a. cannot have a 4 at r7c9
45b. innies of c9 =10 - so no 6 at r3c9

Welcome Howard! Glad you could join us. Smile

Just to clarify Richard's step 44 the options for the 12(3) r456c9 are {138/147/156/246}
{237} is blocked by the 11(2) in N9, {345} is blocked by the 12(2) in N3.
Don't think this has been specified previously.

and a couple more minor steps:

46. Split 25(4) in r4678c6 must have 8 and 9. Options: {1789/2689/3589}

47. Innies r123: r3c12589 = 19. Max from r1589 = 2+3+4+7 = 16 -> r3c2 <> 2

Building on 47 innies

48. Innies = 19(5)={12349}/{12358}/{12367}/{13457}/{13456}
48a. {12349} - no 9 so not poss
48b. {12358} - r3c5=5 r3c189={123} - r3c2=8
48c. {12367} - r3c5=7 r3c189={123} - r3c2=6
48d. {13457} - r3c5=5/7 r3c189={134} - r3c2=7/5
48e. {13456} - r3c5=5 r3c189={134} - r3c2=6
48f. So no 3, 4 at r3c2

Hi all

I am/was still trying to solve it by myself.
I haven't run through all steps but from the last marks pic and the steps afterwards these eliminations are still valid.

[edit] Guess i have nothing to add then

greetings

Para
