Puzzlerium Tour: Stop and Turn

Penpa

Rules: Shade in some cells such that all unshaded white cells (excluding clue cells) can be traversed by a single closed loop that connects the centres of adjacent cells and doesn’t cross or overlap itself. Shaded cells cannot be orthogonally adjacent to each other. Clue cells cannot be shaded. Clues either indicate how many cells in the direction of the arrow are shaded, or, how many cells contain a right angle made by the loop. If a clue cell gives two arrows, the number is true for each of the directions, not all directions combined. Also, if a clue cell contains multiple arrows, it is allowable for one arrow to indicate the number of turns while the other arrow indicates the number of shaded cells.

Puzzlerium Tour: Spotlight

 

Rules: Divide the grid along the gridlines into rectangles such that every rectangle contains two circles and no circle is at the corner (every rectangle 1xn has 2 corners and mxn has 4 corners). No two rectangles of the same area (for example, 5x6 and 3x10) may be orthogonally adjacent.Given bold edges are to be used.

About: Spotlight was invented by Anurag Sahay in September 2021.

Puzzlerium Tour: Tapa

 

Penpa

Theme: Dominos

Rules: Paint some squares to create a continuous wall of connected cells. Number(s) in a cell indicate how many painted cells are contained in a continuous black cell block in its surrounding cells. If there is more than one number in the cell, there has to be at least one white cell separating the black cell blocks. Painted cells cannot form a 2x2 cell. Clue Cells cannot be painted. 

Puzzlerium Tour: Fillomino

Penpa

Rules: Divide the grid along the gridlines into some regions, and fill each of the empty cells with a number. When two cells containing the same number touch along an edge, they must belong to the same region. Given numbers represent the area of the region they belong to. A region may contain none, or one or more of the givens.

Puzzlerium Tour: Masyu

 

Rules: Draw a single loop that consists of horizontal and vertical paths through the centres of cells, and does not intersect itself or enter the same cell more than once, and has to pass through all of the circles. The loop must pass straight through the cells with white circles, making a turn in at least one of the cells immediately before or after visiting each white circle. The loop must make a turn in all the black circles, but must go straight in both cells immediately before and after visiting each black circle.

Puzzlerium Tour: Slitherlink

Rules: Draw a single loop by joining some of the dots. The loop cannot touch or cross itself. Numbers indicate how many of the four surrounding edges are used.

Puzzlerium Tour: Sewage System

  

Rules: Locate some lines that do not intersect with themselves or other lines. Lines are paths that pass vertically or horizontally through the centres of the cells, and have two open ends. Each house (bold outlined region) contains exactly two lines, partially or entirely. Each clue indicates that two identical lines - identical both in length and shape - pass through the cells on either side of the edge containing the clue. The number in the clue is the sum of the lengths (length is calculated as the number of cells used by the line) of the two lines. 'x' marked edges cannot be traversed.

Puzzlerium Tour: LITS (Myopia)

  

Rules: Shade in some cells such that each outlined area contains four shaded cells that form a Tetromino. No 2×2 square can be shaded completely. All shapes must be connected to form a single contiguous group of shaded cells. Identical figures, regardless of rotation or reflection, cannot share an edge. 

Arrows indicate all directions where a shaded cell is closest to the clue cell. Clue  cells may also be shaded.

Puzzlerium Tour: Sensory Data

 

Theme: SENSational NEWS

Rules: Draw a single, non-intersecting unidirectional loop, vertically or horizontally through the centres of the cells. The loop is allowed to pass through clue cells. Number of letters in a clue cell tells that the loop turns in the nearest cell in as many of the four directions, while the letter itself indicates the direction that the path of the loop is heading to right after the turn.

Puzzlerium Tour: LITS (Strings Attached)

It is difficult to not see that this variant bears some similarities with the Outside/First seen variant while allowing the logic to cover a little more terrirory. 

Rules: Shade in some cells such that each outlined area contains four shaded cells that form a Tetromino. No 2×2 square can be shaded completely. All shapes must be connected to form a single contiguous group of shaded cells. Identical figures, regardless of rotation or reflection, cannot share an edge. 

Given letter "A" indicates that the shape in the contained region can be connected to an identical shape in another region with a single straight line that does not turn or encounter any other shape along the way. Multiple connections may exist, but one suffices. Not all possible "A"s are necessarily given.
