Tapa is a logic puzzle. The goal is to blacken some cells of the grid. All the black cells form one contiguous region. No 2 x 2 cell area within the grid can contain all black cells. Clue cells with numbers may not be filled in and tell the length of each consecutive black cell block in the eight surrounding cells. If there's more than one digit in a cell, the groups of black cells have to be separated by at least one white cell. Question marks can be used instead of clue numbers. Each question mark can represent any nonzero integer.

Futoshiki (from Japanese, literally "not equal"; also known as "Hutoshiki", "Unequal") is a logic puzzle. The puzzle is played on a square grid, such as 8 x 8. The objective is to place the numbers 1 to 8 (or whatever the dimensions are) such that each row, and column contains each of the digits 1 to 8. Some digits may be given at the start. In addition, inequality constraints are also initially specified between some of the squares, such that one must be higher or lower than its neighbour. These constraints must be honoured as the grid is filled out.
