Each puzzle consists of a 6x6 grid containing given clues in various places. The object is to fill all empty squares so that the numbers 1 to 6 appear exactly once in each row, column and 3x2 box.

Tents ("Tents and Trees") is a logic puzzle. The playing board is divided into squares. In some of them there are trees. The goal is to place tents in the free blocks by following several conditions: The number of tents and trees are equal. Tent must be located next (horizontaly and verticaly) to at least one tree. There can not be tents near to other tents (horizontally, verticaly and diagonaly). The number of tents in each row, and in each column, matches the numbers given round the sides of the grid.

Ripple Effect (also known as "Hakyuu", "Hakyuu Kouka", "Hakyukoka", "Seismic") is played on a rectangular grid divided into polyominoes. The solver must place one positive integer into each cell of the grid - some of which may be given in advance - according to these rules: Every polyomino must contain the consecutive integers from 1 to the quantity of cells in that polyomino inclusive. If two identical numbers appear in the same row or column, at least that many cells with other numbers must separate them. For example, two cells both containing '1' may not be orthogonally adjacent, but must have at least one cell between them with a different number. Two cells marked '3' in the same row or column must have at least three cells with other numbers between them in that row or column, and so on.

Suguru, also known as Tectonics or Number Blocks, is a Japanese puzzle invented by Naoki Inaba. The goal is to fill a given rectangular grid with numbers, so that every designated area contains a sequence of non-repeating, consecutive numbers, starting from 1 and going up. Also, adjacent (touching) cells should not contain the same number, even diagonally.

The solver is given a 9x9 grid, partially divided by black cells into compartments. Each compartment, vertically or horizontally, must contain a straight - a set of consecutive numbers, but in any order. For example: 7, 6, 4, 5 is valid, but 1, 3, 8, 7 is not. Like sudoku, the solver must fill the remaining white cells with numbers 1 to 9 (or 1 to n in puzzles with N cells per side) such that each row and column contains unique digits. Whereas Sudoku has the additional constraint of 3x3 boxes, in Str8ts rows and columns are divided by blacks cells. Additional clues are set in some of the black cells - these numbers remove that digit as an option in the row and column. Such digits do not form part of any straight.

The Sudoku Chain is similar to the Jigsaw Sudoku, each one have regions of irregular shapes. Consists of a group of circles arranged in a square grid and containing given clues in various places. The object is to fill all empty circles so that the digits appear exactly once in each row, column and chain.
