Chimera

Balance Loop

Rules

• Draw a single non-intersecting loop connecting centers of cells via axis-parallel lines.
• The loop must pass through every circle.
• All white circles must have loop segments of equal length extending from both sides of the circle.
• All black circles must have loop segments of different length extending from both sides of the circle.
• A number indicates the sum of length of the 2 loop segments leaving that circle.
• The loop does not necessarily need to turn on circles.

Castle Wall

Rules

• Draw a single non-intersecting loop connecting centers of cells via axis-parallel lines.
• All white squares must be inside the loop; all black squares must be outside the loop.
• A gray square may be either inside or outside the loop.
• A number and an arrow indicates the total sum of loop segments in that direction. (Alternatively, it indicates the number of borders the loop crosses in that direction)

Masyu

Rules

• Draw a single non-intersecting loop connecting centers of cells via axis-parallel lines.
• The loop must pass through every circle.
• The loop must go straight through every white circle and make at least one turn in either the cell immediately before or after the white circle.
• The loop must turn in every black circle and go straight in both cells immediately before and after the black circle.

Tapa-like Loop

Rules

• Draw a single non-intersecting loop connecting centers of cells via axis-parallel lines.
• Each number represents the number of consecutive cells the loop visits in the 8 cells around the clue.
• If there are multiple numbers, each number indicates a different visit by the loop.
• Each clue contains all visits to the 8 cells around the clue.
• Multiple numbers within a cell are not ordered.
