240 Pocket Killer Sudoku

Killer Sudoku to go.

240 puzzles per book · Pocket size

240 Pocket Killer Sudoku is Killer Sudoku to go. Each compact book holds 240 puzzles in a travel-friendly size, so you can enjoy cages, sums and logic on the train, on holiday or in a waiting room.

There are four books to choose from. Easy to Hard is a gentle start. Medium to Very Hard suits regular solvers. Hard to Extreme is for experienced solvers who want a real challenge on the move. Easy to Extreme mixes every level in one book, so you get a bit of everything, and it makes a good gift when you aren't sure of someone's level.

The rules are classic Killer Sudoku: every row, column and box holds each number once, and the numbers in each outlined cage must add up to its total with no number repeated. A pocket book is a good way to practise the common cage combinations until they become second nature.
