Book Description
Welcome to this brand-new book, containing 100 sandwich sudoku puzzles. This fun sudoku variant is also known as between-1-and-6 and between-1-and-9 sudoku.The rules are simple: first, you must obey the standard sudoku rules. These say that the numbers 1-6 (or 1-9) must be placed once in each row, column, and bold-lined box in the grid. The new 'sandwich' rule works as follows: around the outside of the grid you are presented with a series of numbers: one at the end of each row and each column. These tell you the sum of the numbers that appear between the 1 and 6 (or 1 and 9) in that row/column. This book contains 50 6x6 sandwich sudoku puzzles, and 50 9x9 puzzles. The smallest number that can appear around the outside of the grid is 0, and for a 9x9 puzzle this means that the 0 and the 9 are adjacent in the relevant row/column. The highest number in a 9x9 puzzle is 35 (2+3+4+5+6+7+8), which tells you that the 1 and the 9 must be at the start and end of that region. We hope you enjoy these puzzles. Solutions are at the back should you get stuck or want to check your answers are correct. You will never need to guess to solve these puzzles, but rather apply a combination of standard sudoku solving logic mixed with new logic introduced by the sandwich values around the edge of the grid. Enjoy tucking in!

Book Description
Thermometer sudoku is an enjoyable variant of standard sudoku puzzles, and takes the solving temperature up a little!To solve thermo sudoku puzzles, you need to place the numbers 1-9 once in each row, column and 3x3 bold-lined box that form the grid, as with standard sudoku puzzles. In addition, each puzzle contains a number of thermometers, hence the name of the puzzle. Inside each thermometer, the numbers must increase from the number in the bulb (circled cell) to the opposite end. For instance, a thermometer containing five squares could contain 1,2,3,4,5 or 1,3,5,7,9. However, it could NOT contain 1,3,3,5,7 as that repeats a number, nor could it contain 1,3,5,7,6 as the numbers do not all increase (6 is less than 7).The logic used in thermo sudoku is therefore a charming mix of the logic required to solve sudoku puzzles combined with the logic required to solve futoshiki puzzles (or greater / less than sudoku).All the puzzles in this book of thermometer sudoku can be solved using logic alone, there's never any need to guess when solving these puzzles. And, if you get stuck or just want to check your solution, all the answers are there at the back of the book.
