This canasta score book has 100 pages. Each page has the scoring rules for both the American and classic versions of canasta. The pages are printed with the standard professional canasta score pad information: a table with spaces for player/team names, rounds: base, count and total, with 9 rounds per page, along with the rules for the two main versions of canasta as stated above. This is large size, 8.5 by 11 inches, so plenty of room to write scores.
