Dominosa is a logic puzzle that uses a standard set of Dominoes. The puzzle board represents one of each of the 45 dominoes from 0:0 to 8:8 placed next to each other in an 10 by 9 grid. The problem is, you can't see which squares join to which others to form the 45 dominoes. Your task is find those links, by applying logic to determine a layout for the entire board such that each domino is used only once. Volume 2 This book contains 200 puzzles, 4 per page.
