Puzzlerium Tour: Nanromino

  

Penpa

Rules: Place one pentomino shape in each outlined region without repetitions; cells with given numbers cannot be used. Pentominoes can be rotated/reflected, but cannot touch each other, not even diagonally. Then, insert a number into some of the unused cells so that each outlined area contains at least one number. Each number represents the number of cells containing a number in that area. Where two numbers connect across a region boundary, the numbers must be different. All numbers, including the givens, must form one, connected area with no 2x2 areas of numbered cells. Some numbers may already be given.

Puzzlerium Tour: Pentomania

 

Rules: Place some pentomino shapes, not more than once each (rotations and reflections of the same shape are considered identical). Clue cells remain empty. Shapes do not overlap, but can touch diagonally. Blackened cells cannot be used. Given letters represent all of the pentomino shapes that are edge-adjacent to the cell containing the letter. In the end, all of the unused cells must be connected in a single group through other unused cells.

About: Invented by Anurag Sahay.

Puzzlerium Tour: Ruins

 

Rules: Insert a circle in some of the white cells such that cells sharing an edge do not both contain circles. Given numbers indicate how many of the edge-adjacent cells contain a circle. Then, divide all of the remaining white cells into regions of four or five cells. It must not be possible to traverse any of the obtained regions entirely with a single path that connects cell centers orthogonally and does not intersect or retrace itself. No two identical regions can share an edge.

Puzzlerium Tour: Strings

  

Rules:  Enter a sequence of three or more consecutive numbers inside each outlined region. Each sequence starts with the number 'one', is strictly increasing, and without any empty cells in between two consecutive numbers. No two equal numbers from different regions can share an edge. A region can contain either one or no empty cell. Some numbers are already given. 'x' represents empty cells. Sequences that share one or more edges and are of the same length, cannot have the same shape.

Puzzlerium Tour: Snake Hole

Rules: Shade in some cells such that each given number tells how many cells in the corresponding outlined area are shaded. Shaded cells cannot share borders with each other. Cells with diamonds or black circle cannot be shaded. All of the unshaded cells must be connected in a single group. Starting in each diamond, there must only be one shortest path reaching the black circle; Paths are not allowed to use shaded cells. Two paths of the same length must be unique in shape. Paths may use cells containing other diamonds.

Puzzlerium Tour: Relay Race

    

Rules: Draw a loop that visits all of the outlined regions and moves horizontally and vertically between cell centers. The loop may not intersect itself or pass through any cell more than once. The loop also visits every given circle and has a constant direction throughout. Given numbers tell how many turns follow after leaving the clue cell and before either hitting a region border or another clue cell, whichever comes earlier.

Puzzlerium Tour: Pentopia (Three halves)

 

Rules: Place all of the pentomino shapes, without repetitions, and with rotations and reflections allowed. The shapes may not touch each other, not even diagonally. Arrows point in all directions the pentomino segments are closest to the clue cell. Each bold outlined region must include a full pentomino and a half of another pentomino - half meaning either 2 or 3 cells while the other 3 or 2 cells are contained in an adjoining region.  

Puzzlerium Tour: Souvenirs

Rules: Draw a loop that does not intersect itself and moves horizontally or vertically between centers of all of the cells. Every time the loop enters an outlined area, it visits one given circle before leaving.

Puzzlerium Tour: Koburin (Domino)

 

Rules: Shade some cells such that each given tells how many cells sharing a border with it are shaded, and, each shaded cell shares a border with one other shaded cell, forming dominoes. No two dominoes can share borders. Then draw a single, non-intersecting loop, vertically or horizontally through the centres of all of the white cells. 

Puzzlerium Tour: Pentomino Gallery

Here is the newest innovation from Puzzlerium.

Rules: Place at least one and at most two pentomino shapes (both identical, rotations and reflections of the same shape are considered identical) inside each outlined room. Shapes do not overlap and each shape is placed entirely in its room. Cells with black cells cannot be occupied. Each cell with a white circle has to be contained in a pentomino shape and each pentomino has to contain one white circle. Pentominoes may be rotated and reflected. Two identical shapes can only touch each other at a point.

Puzzlerium Tour: Go Square (Calculated)

Rules: Draw a single, non-intersecting loop, vertically or horizontally through the centres of all of the cells. Given numbers indicate how many 2x2 squares in the corresponding outlined region have all of their four cells visited in immediate succession to each other. If the loop enters region A when leaving from region B, and A and B are visited m and n number of times, m can not be equal to n. Shaded cells are not a part of the puzzle.

Puzzlerium Tour: Geometric Plot

Rules:  Place some non-overlapping rectangles so that given numbers are part of one rectangle each, and each rectangle contains one number that represents its area. Rectangles can only touch each other at a point. Some rectangles may contain no given numbers. Then plot one point (centre of a cell) in each of the rectangles and connect each point with exactly two others so that the edges meeting at a point make one of three angles - 90/45/135 - and form a loop that does not intersect itself. No two consecutive edges are equal in length. Some edges may be given already.

Puzzlerium Tour: Few Good Boxes

Rules:  Place some non-overlapping rectangles so that given circles are part of one rectangle each, the number in the circle representing the area of the rectangle. A rectangle may contain more than one given circle. Then draw a loop that does not intersect itself and moves horizontally or vertically between centers of cells and traverses the entirety of each rectangle represented by a grey circle. The loop enters and leaves the rectangle exactly once. All rectangles represented by black circles must be outside the loop, while all rectangles represented by white circles must be inside the loop. With the exception of cells used by rectangles that are not on the loop's path, the loop visits all of the cells in the grid.

Puzzlerium Tour: Us and Them

  

Rules: Draw lines between cell centres horizontally or vertically, with 90 degree turns allowed, such that each cell is used by one line. Each outlined area contains one or more lines that are entirely inside the area. An area may also contain lines that run into multiple areas but such lines need not necessarily use every area. Lines are always two or more units long (in the number of cells used). The length of an interarea line cannot be equal to that of those lines that are inside any of the areas it passes through. Given numbers indicate there are one or more internal lines of that length. All cells used by all of the internal lines together form a single orthogonally connected network. Some partial/full lines may be given.

Puzzlerium Tour: Sideways

 I had introduced this puzzle type last year.  

Theme: Doubly Clear

Rules: Draw a loop that visits all of the outlined regions. The loop may not intersect itself or pass through any cell more than once. The loop also may not traverse more than two regions successively without making a turn. To state that alternatively, no straight line path may cross two or more borders. Given numbers tell how many cells in the containing region are used by the loop.

Puzzlerium Tour: Land of Honesty

 

Rules: Draw a loop that does not interset itself and moves horizontally or vertically between centers of cells and does not visit the given numbers. Given numbers tell how many of the edge-adjacent cells are used by the loop. Exactly one given in each outlined region is a liar, while the rest of them tell the truth.
