A very quick first placement possible, then lots of places to explore. Enjoyed this as a nice challenge without having to go complex.

Thanks for this week's Assassin, Ed! It was quite hard to solve but that was more my fault since I had to start over twice because of some wrong moves. A293 Walkthrough: Rating: |

I echo Afmob and thanks Ed. Once I got my key step it was not too difficult. Not as hard as the rating suggested. Hidden Text: |

My solution is quite different though in the same areas. Step 9 is the difference [edit: and steps 10 & 11. No one else used step 10 and Andrew found step 11 to be crucial to his WT also]. So, like the others found, bit of a one-trick pony though interesting to have such different "tricks" in the three walkthroughs. Start to A293 22 steps: Ed |

Thanks Ed for your latest Assassin. Ed wrote: A very quick first placement possible, then lots of places to explore. Enjoyed this as a nice challenge without having to go complex. Yes, there's a lot to explore. I got stuck but when I came back a couple of days later I quickly found my breakthrough steps. I didn't need anything complex.Ed wrote: My solution is quite different though in the same areas. Step 9 is the difference. So, like the others found, bit of a one-trick pony though interesting to have such different "tricks" in the three walkthroughs. I was surprised to find that four of us found four different reasons for the first placement.My solving path was more like Ed's than the other two. It would have been better if this puzzle had been posted with the colour pic as the main diagram. It's much clearer than the white one, for those of us who set up our own coloured diagrams. I was surprised that I was able to set up the diagram with four colours, which didn't touch in any place; that's usually difficult to do when there are diagonally connected cages. Here is my walkthrough for Assassin 293: Rating Comment: |

While it maybe hard to find such a colouring it is always doable (excluding remote cages) as the Four color theorem shows. |
