Puzzlerium Tour: Mid-Loop

    

Rules: Draw a non-intersecting loop through the centers of some cells that passes through every circle. Each circle marks the center of the straight line segment it lies on.

Puzzlerium Tour: Fillomino

    

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.

Rules: Shade in some cells so that all of the unshaded cells are connected orthogonally in a single group. Shaded cells may only be diagonally adjacent to each other. Unshaded cells are not allowed to span more than two regions in any straight line. Given numbers tell how many cells in their containing region are shaded.

Puzzlerium Tour: Tapa

 

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: Nurikabe (Distinct)

 

Rules: Shade some cells so that all shaded cells are connected and no 2×2 square is completely shaded. Cells with numbers cannot be shaded. Each group of connected unshaded cells forms an island; islands can touch each other diagonally. Each island must contain exactly one given number, and that number indicates the area of the island in number of cells. Also, all islands of the same size must be distinct from one another. 

Puzzlerium Tour: Fillomino

   

Theme: Tilted Square

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: Anymino

 

Rules: Shade in some cells such that shaded cells in each outlined area form a polymino. 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. Each shape must be adjacent with one or more shapes of the same size as it is.

About: Anymino was invented by Anurag Sahay

Puzzlerium Tour: Pentominous

Rules: Divide the grid into pentominoes such that every cell in the grid is a part of exactly one pentomino. Pentominoes of the same shape (rotations and reflections of a pentomino count as the same shape) cannot touch each other along an edge, but they may touch diagonally. Given letters, if any, must be part of a pentomino with that letter’s shape. It is permissible for a pentomino to contain more than one given letter.

Puzzlerium Tour: House of Pentominoes

    

Rules: Place some pentomino shapes, no more than once each, rotations and reflections allowed (rotations and reflections of the same shape are considered identical). Shapes are not allowed to touch, not even diagonally. Blackened cells (if given) cannot be used. A given number indicates how many cells in that region, including the one it is contained in, are occupied by the corresponding shape. No two given numbers correspond to the same shape. Not all occupied cells within a region need be connected orthogonally.  Each placed shape must include one given number.

Puzzlerium Tour: Expansibility

 

Rules: Divide the grid into pentominoes such that every cell in the grid is a part of a pentomino. Pentominoes of the same shape (rotations and reflections of a pentomino count as the same shape) cannot touch each other along an edge, but they may touch diagonally. The cells separated by any given circle belong to different pentomino shapes. Furthermore, If each cell is numbered based on the number of adjacent cells belonging to the same shape that it belongs to, a given white circle separates two equal numbers and a given black circle separates two unequal numbers.
