Odd-even loop


This is a new puzzle type,to the best of my knowledge.

Puzzle modified for a small uniqueness issue in the middle.

Remembered length


This is a remembered length puzzle.

Double back


This is my first attempt at Double back .I wanted to design a near-symmetrical layout and it turned out to be a cute one, inspite of the redundant parts of the loop.

Design Contest 1 : Result


I think the difficulty of this contest was enough to prevent participation. I have 6 entries,displayed in the image below. All of these were very pleasing solves,the winning entry in particular. The names are written exactly as they called themselves in the mail.


Two of them,Bram and Muhorka, used 14 circles.Bram wins, as his submission was earlier.

Puzzle edited for uniqueness

Tetra stream



Place tetrominos following the rules of nurikabe and LITS at the same time.All unpainted cells should form islands.

Heyawake




Rules:Paint some cells such that all unpainted cells are orthogonally interconnected.Painted cells cannot touch each other through the edges, but they can touch diagonally. Sequences of horizontal or vertical white cells must not belong to more than two different rooms.Numbers in some rooms indicate how many painted cells the room contains.

Tentamino



Rules: Place a tent adjacent to every tree.Tents cannot touch each other.Every outlined region contains two tents.Numbers outside indicate the number of tents in that direction.

LITS and more


This is the second LITS and more puzzle.Much harder than the first one. Rules: Place a pentomino in every outlined region.All painted cells should form a single wall of orthogonally connected cells.Pentominos of the same shape cannot touch through edges.

Hidato


Rules: Starting in any cell,write a number from 1 to 25 into one of the empty neighbouring cells,moving horizontally or vertically or diagonally.Some numbers are given.

Masyu - Non-identical neghbours

This is another masyu variation that i developed recently.
Rules: Draw a single closed loop passing through adjacent squares,moving only horizontally or vertically.The loop cannot visit any square more than once.At every white circle,the loop must go straight and turn on either or both of the squares visited immediately before and immediately after.At every black circle, the loop must turn,and go straight through both the squares visited right before and right after.Additionally,after the puzzle is solved,you cannot legally place a circle of the same color orthogonally adjacent to any of the given circles.

Myopic fencing


I think myopia and fences make a good combination.Both are loops along the edges and clues from each type work together nicely.This introductory example is almost easy.

Rules: Draw a single closed loop along the gridlines.The lines indicate the direction in which the loop is the closest to that cell.The numbers indicate how many edges of a cell are used by the loop.

Snake eyes


I like the puzzle myopia.I thought this could be combined with snake.

Rules: Draw a snake,1-cell wide,not touching itself.The snake cannot visit the clue cells.The clues indicate in which direction(s) the snake is closest to the cell as seen form the cell.

Briquet



This is a briquet.I first saw this type at the OAPC. I designed a symmetric layout for this.The opening is easy,but the difficulty rises in the second half.The empty space in the middle did not go wasted. Rules:
Place 2 sets of 6 rectangular slabs of 1x3 size ,without touching,each slab having a different permutation of the numbers 1,2,and 3.One set should be horizontally placed ,and the other vertically.
