Bonsan: Move some circles so that circles are 180° symmetrically placed. A circle may move only in one straight path vertically or horizontally. Paths may not cross other circles or their paths. Numbers indicate how many steps to move a circle. puzz.link/p?bonsan/c/12/…

Islands Shade a single group of orthogonally connected cells in each region. Shaded groups may not share a bold border. Each region must contain at least one shaded cell, and no two adjacent regions may contain the same number of shaded cells. puzz.link/p?shimaguni/10…

Slant Place a diagonal line into each cell, connecting two opposite corners, such that no loops are formed by the diagonal lines. A clue in a circle indicates how many lines are extending from that circle. puzz.link/p?gokigen/5/5/…

Nuribou Shade some one-wide rectangles of shaded cells. Same-size rectangles may not touch diagonally. Clues cannot be shaded, and every orthogonally connected area of unshaded cells contains exactly one clue, representing the size of the area. puzz.link/p?nuribou/9/9/…

Ayeheya Shaded cells don't touch orthogonally. All unshaded cells are orthogonally connected. Numbers give # of shaded cells in the region. Shaded cells in a region have 180° rotational symmetry. A line of unshaded cells crosses no more than one border. puzz.link/p?ayeheya/10/1…

International Borders Each area of unshaded cells contains all clues with a particular shape (at least one). Clued cells are unshaded. Numbers count orthogonally adjacent shaded cells. A shaded cell must be orthogonal to 2+ different unshaded areas. puzz.link/p?interbd/10/1…

Nuri-Uzu Shade some cells such that each group of orthogonally connected shaded cells contains exactly one circle and has 180° rotational symmetry around it. No 2x2 area may be entirely shaded or unshaded. pzprxs.vercel.app/p?nuriuzu/15/1…

It's very incomplete, but I think it's finally in a state that I'm ready to drop the link publicly. If anyone (especially those newer to heyawake) has constructive criticism/feedback, I'd love to hear it! tinyurl.com/HeyawakeGuide

Yajilin Shade some cells. No 2 shadeds are orthogonally adjacent. Draw a non-intersecting loop through all the remaining empty cells. Clues are unshaded, and represent the number of shaded cells in a straight line in the indicated direction. puzz.link/p?yajilin/b/6/…

On my 1 year Twitter aniversary, I'll share a puzzle genre that I invented and that has been adopted by some others. Anguru is simple on paper, but can lead to some interesting deductions. In my next post, I'll show you the first Anguru that I made. (1/2)

(2/2) Anguru 1 Divide the grid into L-shaped regions of four orthogonally connected cells. Borders must separate two different regions. Two regions which are the same orientation may not share an edge. Puzzle link: tinyurl.com/2hq88pv3

Gentleman is 93. Lived though a lot. That's the small talk as Ukrainian volunteers rescue him from Russia's flood. Now he's lived through that and the shrapnel that hit him when Russians fired at the boat.
