Beginner's Guide to Variant Sudokus
(Eingestellt am 24. Januar 2024, 07:01 Uhr von juggler)
(If you're already an expert, you can also speed-solve all 8 back-to-back. Let me know your total solving time in the comments!)
***********************
In all of these puzzles, normal sudoku rules apply: fill the grid with the digits 1-4 (or 1-6 for the 6x6 puzzles) so that no digit repeats in any row, column, or box.
I. Introduction to Killer Sudokus
Play on Sodukupad
KILLER
- Digits in cages sum to the number in the corner of the cage.
- Digits cannot repeat within a cage.
LITTLE KILLER
- Digits along the diagonal indicated by an arrow sum to the number by the arrow.
II. Introduction to Kropki Dots
Play on Sodukupad
PARTIAL KROPKI
- A white dot between two cells requires that the value in one cell is exactly 1 greater than the value of the other cell.
- A black dot between two cells requires that the value in one cell is exactly double the value of the other cell.
Note: This is called "partial" kropki because some puzzles use the "full kropki" rule, where you are told that all possible dots have been given, and can make conclusions based on lack of dots between cells.
III. Introduction to XV
Play on Sodukupad
PARTIAL XV
- Two cells separated by a V have values that sum to 5.
- Two cells separated by an X have values that sum to 10.
IV. Introduction to Arrows
Play on Sodukupad
ARROWS
- The digits on the line part of an arrow sum to the value indicated on its circle / obround.
- The obround represents a two digit number, read from left to right.
V. Introduction to Anti-Knight
Play on Sodukupad
ANTI-KNIGHT
- If two cells are a knight's move apart (i.e. two steps horizontally and one step vertically, or vice versa), then they cannot have the same digit.
(this puzzle also uses the Partial Kropki rule from earlier)
VI. Introduction to Thermometers
Play on Sodukupad
THERMOMETERS (also called "thermos" for short)
- Digits strictly increase in value along a thermometer, starting from the bulb end.
- It's not required that adjacent cells have adjacent values, for example 1-3-4 or 2-4 would both be valid.
VII. Introduction to Renban Lines
Play on Sodukupad
RENBAN
- Digits on a purple Renban line must be a set of consecutive, non-repeating digits (in any order). For example, a length 3 line could have -3-1-2-, but not -1-2-4- or -1-3-1-.
VIII. Introduction to Counting Circles
Play on Sodukupad
COUNTING CIRCLES
Any digit in a circle indicates exactly how many circles contain that digit. As an example, if there is a 2 in any circle, there are exactly two 2s in circles in the puzzle.
Fun fact: counting circles first appeared in 2023 in this puzzle by Marty Sears.
Lösungscode: The number in the lower right cell of each of the 8 puzzles, in order.

Sudokusnacks indeed. Fun and quick solves. I had the most trouble with the last puzzle, but mostly because I hadn't seen that variant before. My intuitive approach worked, but I'll have to look into why I'm right.

I just spent the whole afternoon solving 4x4 "Snackdokus" and this is the first puzzle I come across today on LMG? Challenge accepted. :D Took me 3:36 in total.
Very enjoyable 3 and a half minutes, might I add.

I love these. Exactly what should be part of some introduction/guide on basic rules.

I have rushed through these nice little puzzles as well. It almost felt like eating chocolate where you can not really stop, but always need a next bite. :)
Thank you for setting and sharing, juggler!

Even thought it’s really easy, it’s really fun anyway. Great for its purpose. Perfect for letting my son start with variants.

A bunch of fun little puzzles. Very easy, but definitely should be pretty approachable to someone new to sudoku.
Decided to speed solve them, as suggested, and took 6:09 in total.

Fantastic job setting these. I'll be passing this along to friends who want to learn!

Excellent introduction, though almost beginner I had a nice time solving these
Total time around 16 min, spent 6 minutes on the kropki puzzle
