This puzzle is unfortunately very clunky … It slipped the net.

I'm in the process of generating a new batch of puzzles that are of a better quality to the emergency batch I generated at the start which we are currently using. I'll see if I can start posting from the new collection from tomorrow!

Yes, I had a sequence of 11 AIC's or so to overcome it, and I didn't dare to post it...
To tell the truth I didn't felt like putting it in form !

Hi Tarek and Cenoman,
This puzzle gave me a hard time, but here's a 4-step solution with TDP.

Step 1 with an anti-track :
P'(1r4c3) : -1r4c3-> --- ->2r8c2 and 1r2c7 (see diagram and puzzle1) => -1r2c3, -1r8c3 => r4c3=1

Code: Select all
           -----------------------------------
          |                                   |               
-1r4c3->1r4c2->9r1c2->4r7c2                   |            -----------------------
     |                                        |           |                       |
      ->[(5r4c3->6r6c3)->4r5c3]->7r7c3->7r3c2->6r9c2->78r9c45->2r9c8->2r3c1->2r8c2->1r9c9->1r2c7
                                   |                         |                    |
                                    ->56r7c89->-----------------------------------

Step 2 with an anti-track :
P'(5r4c5) : -5r4c5->9r4c5->9r5c1->4r5c3->5r6c3 (see puzzle2) => -5r6c5 => r6c5=7 and 6 placements

Step 3 with an anti-track :
P'(6r9c8) : -6r9c8->253r469c8->-2r3c8->2r3c1-> --- ->6r1c8 and 2r2c7 (see diagram and puzzle3) => -6r37c8, -2r2c9

Code: Select all
                                                             ------------------------------
                                                            |                              |
-6r9c8->253r469c8->-2r3c8->2r3c1->2r8c3---------->7r7c23->7r3c8->6r3c2->7r2c3              |
                             |       |       |                            |                |
                             |        ->1r9c2->4r8c1->---------------------->4r1c2->6r1c8  |
                             |                   |                                         |
                              ---------------------->1r2c1---------------------------------->2r2c7

Step 4 with two conjugated tracks :
P(2r3c8) : 2r3c8->2r6c7->6r5c7
P(7r3c8) : 7r3c8->6r3c2-> --- ->6r6c3 (see diagram and puzzle4) => -6r5c13 => r5c7=6, stte.

Code: Select all
         ------------------>7r2c3
        |                     |
7r3c8->6r3c2->2r3c1->2r8c3    |
        |              |      |
        ->1r9c2--------->4r8c1->4r1c2->6r1c8->5r9c8->5r7c3->6r6c3
