Nauticalia

Our "thinking man's game console" comes loaded with 30,000 crossword questions and over a million Sudoku grids - perfect for whiling away night watches at sea, or long distance train and plane journeys.

You can choose from three levels of difficulty depending on how ambitious you're feeling, and there is a help/cheat option if it becomes too much of a struggle.

Simple to operate (the buttons that is, not the level 3 puzzles!) and, at 4½" square, compact without being impossibly small to read or type on. Uses two AAA batteries (see 93194 below).
