Gather round to celebrate! Today marks the 2nd anniversary of the GAPP series. Enjoy this little puzzle collection we put together for the occasion! The plan was to have one puzzle from each team member, whether setter or tester, past or present, but of course participation was optional for former members. As such, Shye has made an extra Ring-Ring to honour Riri's contributions as a tester, and we've all come together and collaboratively constructed the final puzzle to fill in for Tyrg. With so many puzzles, we don't have space for examples today, but all of these genres have appeared on GAPP before, so you can search in:daily-pencil-puzzles if you need a refresher.

A is for Aqre (by Freddie): https://tinyurl.com/ypb67xd3
Shade some cells so that all shaded cells form one orthogonally connected area. Regions with numbers must contain the indicated amount of shaded cells. There may not exist a run of more than three consecutive shaded or unshaded cells horizontally or vertically anywhere in the grid. The "X" only clarifies that this cell is not part of the grid. It is considered neither shaded nor unshaded.

N is for NIKOJI (by Lavaloid): https://tinyurl.com/yr55npvd
Divide the grid into regions of orthogonally connected cells, each containing exactly one clue. Regions with the same clue type must be exactly identical in shape, orientation, and position relative to the clue. Regions with different clue types may not be the same shape, counting rotations and reflections as the same.

N is for Nurimisaki (by Shye): https://tinyurl.com/2x3x244j
Shade some cells so that the remaining unshaded cells form one orthogonally connected area. No 2x2 region may be entirely shaded or unshaded. Circles mark every instance of a cell which is unshaded and orthogonally adjacent to exactly one other unshaded cell. If a circle contains a number, it indicates how many cells are in the straight line of unshaded cells coming out of the cell with the circle, including itself.

I is for Icelom (by Walker): https://tinyurl.com/ysnu4eak
Draw a path through the centers of some cells, entering the grid at the “IN” marking and exiting at the “OUT” marking. All non-icy cells must be visited, and all cells containing numbers must be visited in increasing order. Two perpendicular line segments may intersect each other only on icy cells, but they may not turn at their intersection or otherwise overlap. The path may not turn on icy cells.

V is for Voxas (by Menderbug): https://tinyurl.com/222scxc2
Divide the grid into 1x2 and 1x3 regions. Borders must separate two different regions. Borders with white dots separate regions with the same size and orientation. Borders with black dots separate regions with neither the same size nor the same orientation. Borders with grey dots separate regions with either the same size or the same orientation, but not both.

E is for Every Second Straight (by Eric): https://tinyurl.com/yofxekow
Draw a non-intersecting loop through the centers of all cells. Every second cell in which the loop goes straight is marked with a circle.

R is for Reflect Link (by bakpao): https://tinyurl.com/yoybuef2
Draw a non-intersecting loop through the centers of some cells. Two perpendicular line segments must cross each other at given intersections, but nowhere else. Every triangle must be touched by the loop. Triangles reflect the loop at right angles, and a number in a triangle indicates the total number of cells that the lines coming out of it travel to before turning, including the cell the triangle is in.

S is for Square Jam (by xoned): https://tinyurl.com/yn8y8goh
Divide the grid into square regions of orthogonally connected cells. A number indicates the side length of the square it’s in. There may not be a point in which 3 or 4 regions meet up at a corner. (Note the slight change in the rules to account for the non-rectangular grid.)

A is for Aho-ni-Narikire (by jovi_al): https://tinyurl.com/yn5ntm3o
Divide the grid into regions of orthogonally connected cells. Each region must contain exactly one clue, the value of which represents the number of cells in the region. If the number of cells in the region is a multiple of 3, the region must be an L shape (a rectangle with another rectangle smaller in both dimensions removed from a corner). If the number of cells in the region is not a multiple of 3, the region must be rectangular.

R is for Ring-Ring (by Shye): https://tinyurl.com/yraa6le9
Draw rectangular loops through the centers of empty cells so that every empty cell gets used. The sides of different rectangles may intersect each other, but not turn at their intersection or otherwise overlap.

Y is for Yajisan-Kazusan (by GAPP team) https://tinyurl.com/yv3hqmux
Shade some cells so that no two shaded cells are orthogonally adjacent and the remaining unshaded cells form one orthogonally connected area. If a cell with a number in it is unshaded, the number represents how many shaded cells are in a straight line in the indicated direction. If a cell with a number in it is shaded, the number is meaningless. Clues cannot see past the gap in the top half of the grid.
