The goal of CalcuDoku is to fill the grid in with the numbers 1-N (N is the number of rows/columns in the grid) such that:

• Each row contains exactly one of each number.
• Each column contains exactly one of each number.
• Each bold-outlined group of cells (cages) contains numbers which achieve the specified result using the specified mathematical operation (+, -, ×, ÷). Sometimes the sign +, -, × or ÷ is omitted, in which case you also need to find the correct sign.
• Numbers may repeat within a cage.

The goal of Futoshiki is to place one number in each empty cell, so that each column and row contains each number exactly once. Some numbers may be given at the start. In addition, inequality constraints are specified between some of the squares, such that the number must be higher or lower than its neighbor. These constraints must be honored as the grid is filled out.

I guarantee that every logic puzzle in this CalcuDoku book has been carefully checked to ensure that each puzzle has only 1 solution.

CalcuDoku is also known as Square Wisdom, CanCan, MinuPlu, Mathdoku and Calcu-Doku.
