Weekly Assassin 14 1st September

Post by Andrew »

Escaped. The prison needs stronger bars!

Here is my walkthrough.

1. 45 rule on R12 -> R2C5 = 4, R34C5= {23}, 45 rule on R89 -> R8C5 = 7, R67C5 = {58}, R159C5 = {169} with R1C5 = {69}, R9C5 = {16}

2. 23(3) cage in N7 = {689}, 45 rule on C1 -> R37C1 = 14 = [95], R89C1 = {24}, R67C5 = [58], 7 in N7 locked in R7 in R7C23, 7 in N9 locked in R9 in R9C78, 17(3) cage in N9 cannot contain a 3, R8C34 = [35], R8C67 = {49}, R89C1 = [24], R89C9 = [15], R7C23 = {17}, R8C8 cannot be 6 so R8C28 = [68], R9C78 = {27}, 45 rule on C9 -> R37C9 = 15 = [69], R8C67 = [94], R7C6 = 4, R7C78 = {36}, R6C6 = 2, R34C5 = [23]

3. R12C9 = {27}, R456C9 = {348}, R67C4 = [62], R5C5 = {19} -> R5C456 = {189}, R4C46 = [47], R3C678 = {458} -> R3C8 = 4, R3C234 = {137}, 9 in N3 is locked in the 15(3) cage which must be {159}, R3C67 = [58], R2C67 = [63], R7C78 = [63], 16(3) cage in N6 = {259} -> R6C7 = 9, 14(3) cage in N6 = {167}, R9C78 = [72], R1C7 = 1

4. R12C1 = [81], R3C4 = 1, 16(3) cage in N4 = {367} -> R4C1 = 6, 45 rule on N1 -> R2C34 = [28], 15(3) cage in N1 = {456} -> R2C2 = 5, R1C23 = [46], R159C5 = [916], R1C46 = [73], R5C46 = [98], R9C46 = [31], 2 is locked in C2 in N4 so 12(3) cage = [921], 17(3) cage in N4 = {458} and carry on, the rest is simple elimination

Easy Assassin, just pick the right innies, and be carefull or you will have to restart...
done little less than one hour.
I would rate it 0.50
Nothing can both be and not be
