Arrow collection part 1

(Eingestellt am 30. Juni 2021, 09:56 Uhr von bigger)

Standard sudoku rules applies. Fill the grid with numbers from 1 to 6 so no repeated digit in every row, column and 2x3 box.

The digit in the circle is the sum of the digits along the arrow. The following variant change some part of the rule.


Let’s start easy. The circled digit has a difference of 1 with the sum of the digits on the arrow.

Now, let’s keep the arrow part the same, the sum is still the circle. Filled the grid with 1-5 and a mystery digit X. X can be any digit from 1 to 5, but all X has a same value.

Filled the grid with 1-7 so no repeat digits occurs in every row, column or box.

Filled the grid with only 6 digits from 1-9. Pick 6 digits from the 9 and complete this one.

These puzzles are made by Old Miles from China around December, 2019. I didn’t provide that much ideas at that time. Some ideas might came from WSC. I just want to make a compilation of arrow variants. I don’t think these four are new variants, just uncommon. The last three are actually the star adder for any 6X6. If a 6X6 is too easy but I don’t want a 9X9, which is highly impossible, I would asked Old Miles to slap one of these three on. As for 9X9, I don’t think anybody want to deal with 9+ uncertain digits. Anyway, where is fry the seventh puzzle?

Lösungscode: 2nd column of the first one, 3rd row of the second(replacing X with its value), 2nd column of the third, 6th row of the forth(24 digits)
