TVC X Practise Part 1

I will do these practise puzzles in two days. Some of the types don't come as easy as others. I try to put in something that will help learn a bit about a variant, so that it will actually be helpful.

Total False Tapa is still a tricky genre. I think the logic path is better than my previous one.
Tapa Guard is more like the puzzle in the test I hope this time. Last time I was happy with the result, but not completely applicable to the test.
Tapa and Pata is the same puzzle as my Double Trouble #4. I might make a new one, but I find the gimmick very hard to acchieve. Both puzzles are somewhat challenging.
Toroidal Tapa is the puzzle I'm happiest about in the set. The edge 2x2 squares are the hardest to keep track of when solving.
Braille Tapa is not my favourite variant. Somewhat interesting to disallow certain shapes, but it can sometimes be a bit limiting in design.
Combination Tapa doens't always feel like you are doing a Tapa. I'm happy with how I managed to get the grey cells to work out.

You can find the puzzles below.

Rules for Tapa

1a. Total False Tapa

Regular Tapa rules. Additionally, all given clues are false. This means that the correct number of digits in that cell is different from the given number of digits. Also, all digits in the cell are different from the given digit(s). Correct clues can't contain a zero.

1b. Tapa Guard

Tapa clues have 2 functions:
1 - They function as normal Tapa clues.
2 - They indicate how many coloured cells can be seen in the corresponding directions. A digit in an undivided cell, may observe in any of the four directions.

2. Tapa and Pata

This puzzle can be solved as a regular Tapa puzzle and as a Pata puzzle. In Pata the clue numbers indicate the amount of white squares instead of the amount of coloured squares.


3. Toroidal Tapa

Follow regular Tapa rules. Additionally the grid wraps around all four edges.


4. Braille Tapa

Follow normal Tapa rules. Additionally each marked 2x3 rectangle has to contain one of the given Braille letters.

5. Combination Tapa

Follow regular Tapa rules. All grey cells should contain clues with digits 1-5. All grey clues are different. The digits outside the grid indicate the length of the first segment seen in that direction.

  1. Nice set again. I really liked the totally false and the Combination. I found the Tapa part of Tapa and Pata quite easy but thats probably due to all the Classic Tapa practice lately ;)

    Not yet done Braille and Toroidal, but I agree with you that Braille is limiting, and personally I've never been good at Toroidals, so won't have much to say about those anyway.


    1. Thanks. The Totally False was a better than my first one. Combination my own verdict isn't totally out yet. The Tapa probably was easier than I remembered, but I have to admit I didn't actually resolve them before I posted.

  2. Indeed,its kind of hard to achieve a grid which is a tapa and a pata both,more so if you are aiming a symmetric placement of givens.

    1. The symmetry constraint is what makes it hard, I can push them out if I don't care about that much. I had seen the points for them and figured it wouldn't be that necessary to make a second example, which I wasn't too happy with.

    2. I enjoyed your total false more than others,moderate difficulty was the pleasure factor here i think.I am sure you want to write more of those.

  3. Nice Set of puzzle for practice. Thanks Bram
