Mathrax consists of a square grid.The goal is to fill in each cell with numbers from 1 to N, where N is the size of the puzzle's side.No number may appear twice in any row or column.Circles with additional conditions may be situated on intersections of lines inside the grid. A number and a sign of mathematical operation (addition, subtraction, multiplication, division) - a number is a result of an operation execution with numbers in diagonally adjacent cells.A letter "E" ("even") - all numbers in four cells are even.A letter "O" ("odd") - all numbers in four cells are odd.

Masyu is a type of logic. The purpose of its creation was to present a puzzle that uses no numbers or letters and yet retains depth and aesthetics. Masyu is played on a rectangular grid of squares, some of which contain circles, each circle is either "white" (empty) or "black" (filled). The goal is to draw a single continuous non-intersecting loop that properly passes through all circled cells. The loop must "enter" each cell it passes through from the center of one of its four sides and "exit" from a different side, all turns are therefore 90 degrees. The two varieties of circle have differing requirements for how the loop must pass through them: - White circles must be traveled straight through, but the loop must turn in the previous and/or next cell in its path. - Black circles must be turned upon, but the loop must travel straight through the next and previous cells in its path.

Knossos is a logic puzzle ("Knossos" is a palace on Crete; this palace is connected with ancient legends, such as the myth of the Labyrinth with the Minotaur). It is played on a rectangular grid. Some of the cells in the grid are numbered. The goal is to divide the grid into regions ("rooms") such that each region contains exactly one number, and that number represents the border's length of the rectangle.
