Hitori:
Black out squares to ensure no repeated numbers in rows/columns, no adjacent black squares, and all unblacked squares are connected.
Sudoku:
Four difficulty levels. Features include Pencil Mode, Undo/Redo, Auto-fill Candidates, Candidate Lock, and Eraser Lock.
Nine Find:
Circle each number 1-9, ensuring the sum in each row and column does not exceed 9.
Oneness:
Turn all numbers into 1!
Kuromasu:
Black out cells to ensure numbered cells see the correct number of white cells, no adjacent black cells, and all white cells are connected.
Slitherlink:
Connect dots to form a non-crossing loop. The number of segments around each number must match the number.
Skycrapers:
Place skyscrapers so that their heights are unique in each row and column. Side numbers indicate visible skyscrapers.
Binairo:
Fill squares with X and O ensuring no more than two consecutive X's or O's, equal numbers of X's and O's, and unique arrangements in each row and column.
Dominosa:
Pair adjacent numbers, each pair appearing only once. Click between numbers to form pairs.
Battleships:
Locate hidden battleships. They cannot touch each other, even diagonally. Row/column numbers indicate occupied cells.
Tent Puzzle:
Place tents next to trees on the grid. Each tent must be adjacent to a tree, and tents cannot touch each other, even diagonally. The numbers outside the grid show how many tents are in each row and column.
Light Up:
Light Up is played on a rectangular grid. The grid has both black cells and white cells in it. The objective is to place light bulbs on the grid so that every white square is lit.
Shikaku:
You have to divide the grid into rectangular and square pieces such that each piece contains exactly one number, and that number represents the area of the rectangle.
Minesweeper:
Find all the mines.
Renzoku
Fill all cells with unique numbers in each row and column, ensuring adjacent cells connected by a dot differ by 1, and those not connected differ by more than 1.
Masyu:
You have to draw lines between the dots to form a single loop without crossings or branches. The loop should pass through all black and white circles in some way.
FourWinds:
Draw lines from the given numbers in the four directions (up, right, down, left). The number represents the sum of the squares the line passes through (excluding itself).
Nurikabe:
Draw connected black walls to separate the white islands according to the following conditions.
Arrows:
Adjust the direction of the arrows so that the number in each square equals the sum of arrows pointing to that square.
Gappy:
Color some squares black so that the number of white squares between two black squares equals the numbers outside the grid.
Doppelblock:
Fill the board with black squares and numbers so that each row and column contains the numbers 1 to N and two black squares, where N is the board size minus 2.
EulerSquare:
Fill the board so that each cell contains a unique combination of a letter and a number, with no repeats in any row or column.
