Показать описание
Come chat with us as zetamath solves puzzles and talks about setting!
Regular streams are on Fridays at 2 PM Central US Time (20:00 UTC; 5 AM Saturday AEST) and Sundays at 11 AM Central time (17:00 UTC; 2 AM Monday AEST). Additional streams on an ad hoc basis.
We accept puzzle suggestions only from our Turbine-level supporters.
If you are a creator and you do not want us to do your puzzles on stream, please let us know in the comments or on Discord.
Stream rules:
1. Be respectful to me and to everyone else, whether they are present in chat or not.
2. Help with the puzzles is welcome!
3. If I mispronounce your screen name, please tell me and I will do my best to pronounce it how you like.
4. This stream supports trans rights. There will be no debate about this in chat. I endeavor to get people's pronouns right, and if I do not know someone's preferred pronouns I will default to they/them.
Puzzles done this stream:
"7 Day Forecast" by Malrog
Normal sudoku rules apply.
Thermo: Along thermometers, digits must strictly increase from the bulb end.
"Kropki Cave Loop" by yttrio
Normal Sudoku rules apply.
Draw a one-cell-wide loop of orthogonally connected cells. The loop may not touch itself, not even diagonally.
Adjacent digits along the loop must have a Kropki relationship. That is, they must either be consecutive or have a 2:1 ratio.
Digits in circles are on the loop, and give the total number of loop cells (including itself) seen in all horizontal/vertical directions combined. Non-loop cells block the vision.
Digits in squares are NOT on the loop, and give the total number of NON-loop cells (including itself) seen in all horizontal/vertical directions combined. Loop cells block the vision.
"Invisible Renban" by ClashCode
Japanese Sums: Shade some cells in the grid and place digits from 1-9 into each unshaded cell such that no digit repeats in any row/column. Clues outside the grid show the sums of digits in contiguous unshaded cells in the respective row/column in order from the left/top to right/bottom.
Cave: All unshaded cells must be orthogonally connected. Shaded cells must connect orthogonally to the edge of the grid.
Invisible Renban: Every row/col must be a set of consecutive digits in any order.
"Coincidence" by Fuxia
Normal Sudoku rules apply.
Digits along an arrow sum to the number in the attached circle.
"Dual Masyu #2" by Paletron
Draw two non-branching loops through the centers of orthogonally connected cells. The loops may cross one another on straight line segments, but each loop may not cross itself. All circles must be visited by at least one loop. Loops must turn on black circles and travel straight through the cells on either side. Loops must go straight through white circles, and turn in at least one of the cells on either side. Loops can cross each other on white circles.
