Puzzle 24: Trimino Divide

This puzzle was made for WPC 2016 practice. Rules (from the IB): “Divide the grid along the given lines into triminoes. Each trimino is formed by three orthogonally adjacent cells. When there is a cross between two triminoes, they must be of a different shape. When there is a triangle between two triminoes, they must be of the same shape, but different orientation. When there is a dot between two triminoes, they must be of the same shape and the same orientation. Symbols always lie on a trimino border, not inside a trimino.”

Puzzle 23: Black Hole Tapa

Rules (copied from the TVC instruction book): Follow regular Tapa rules. Additionally, each row/column must contain N Black Holes. Black Holes must be placed on the Tapa wall. For the purposes of surrounding clues, a cell with a Black Hole counts as M consecutive shaded cells instead of 1. Black Holes may touch each other. N and M will be given in Puzzle Booklet.

Also, in this puzzle, one of the clues has a 0 in it. I think the meaning of this should be natural, but just to be precise, the 0 must correspond to a non-empty group of black cells whose total length (adjusted for black holes) is 0.

Edited to add one more clarification: Even though the black holes count as 0 for clue purposes, they still count as black squares for everything else (black holes count for connectivity, you can’t have a 2×2 square of black holes, etc.)

Notes: Well, I suppose I’m still alive. 😛

After going to the WPC (I’m currently writing a recap and hope to have it finished at some point), I’ve been motivated to get back into making puzzles after I basically had no time at all the past year due to school/burnout. So, have some TVC practice! Although I’m not sure whether this puzzle is representative of a typical Black Hole Tapa, as M=0 is a little unusual heh.

Puzzle 22: Nurikabe (pairs)

with one comment

Rules from MellowMelon’s blog: This is a Nurikabe puzzle, with a twist. Every region of unfilled cells must contain exactly two numbers (instead of one) and have total size equal to the sum of the two numbers.

Notes: After a 3 month break, and thanks to a 2-hour long physics class, we’re back. 😀 Also, there’s no hidden valentine’s day theme or anything (I didn’t even know that it was valentine’s day until I saw students carrying around flowers today, heh). The 2s are, well, for puzzle 22, and feel free to count how many 2s there are.

On another note, I might post a more detailed mystery hunt recap sometime. Out of the logic puzzles I remember, Portals was amazing, Agricultural Operations was cool, A Regular Crossword was cute, and Random Walk was okay but had lots of trial and error. Palindrome was an awesome team to solve with, as usual!
