Shame on me :oops: I verified this puzzle with Richard's solver and it gave a rating of 1.38, which is usually on the spot for an Assassin. The phrase "******* Puzzle Not completed. *******" just scrolled out of sight in the solver log. The Assassin has been replaced with a more suitable p...

Here's a move that I used a few times in A84 and its V2. Pattern definition: Cage A and cage B are located in a single house. Digit X can only be placed in one of these two cages within that house. Digit Y is a digit which must also be placed in cage A , when X is placed. Theorem: If the pattern def...

This week I've been the victim of a virus explosion in my head. I felt totally clueless. :pale:

Feeling better now, and hopefully I have been able to replenish all the puzzle stocks on site, including the Clueless Explosion.

Happy New Year to all.

Comparing notes

After some heavy modifications to SumoCue, I have compiled a table with the ratings for all (currently 82) original Assassins, with the new SumoCue rating, the (average) human player rating and the rating by Richard's Sudoku Solver. Since player ratings started with A50, there are only a few post-ra...

Killer X-mas tree

Here is a V2X of this week's Assassin. It is solvable by logic, but you need a lot of it. Fortunately, you will have a little more time now with the upcoming Holidays, for which I wish you all the best. http://www.sudocue.net/images/killer-xmas-tree.png 3x3:d:k: 4608:4609:4609:4609:3332:5125:5125:51...

Just a little step: both candidates for {0-5} eliminate {0-6} in r3-4c10. This leaves a hidden single {0-6} elsewhere in the grid. Ruud (Edit:) Candidates for {6-8}: when r3c10-11 is true, a tunnel forces r1c5-6 to {7-8}. The alternative {6-8} is r1-2c4. Eliminate r1c4-5. The next step is a contradi...

Thanks for all the suggestions, George, Pete & Rep'nA (I knew there was a way to revive you, Adam 8-) ) The rating problem is noted and will be fixed quickly. Actually, the rating you see is that of the last puzzle generated by the program. It should be updated when you paste/open an existing pu...

Gemma, je kan in elke volgorde zoeken, maar voor het overzicht zijn alle mogelijke combinaties in oplopende volgorde rechts op het scherm geplaatst. Je moet denken aan echte dominostenen. De combinatie 8-6 is gelijk aan 6-8 als je de steen omdraait. Het leuke is dat diverse oplostechnieken vergelijk...
