After a long wait the new version of Big Bad Sudoku Book is being launched today: Sudoku Book 3 It might take a few hours before it shows the update available everywhere as we just set it to release moments ago. http://itunes.apple.com/us/app/sudoku-book/id364907966?ls=1&mt=8 Sudoku Book 3 is a major update to Big Bad Sudoku Book and introduces 3 major new features: Themes, Puzzle Book, and we are also launching Game Weasel, our high score system. Version 2 had the Campaign mode which was 50 puzzles with a Game Center leaderboard. We took that idea and expanded it. With Puzzle Books you can play through a book of themed puzzles and each book has it's own leaderboard fueled by Game Weasel. Books are available both as free downloads and as In App Purchases. All the IAP book bundes are 4 Books for $1. Books contain a campaign of hand picked puzzles, often in a specific visual pattern theme. INVASION! is a very cool series of puzzles that were inspired by retro video games. Game Weasel is our high score system and is a free service. Sign up and you'll be able to track 100's or eventually even 1000's of statistics and see your world wide ranking in each category. Finally, themes are more than just skins. At launch we're offering Tin Toy, which turns the game into a metallic looking retro game. Tin Toy is also only $1 and comes bundled with an exclusive puzzle book. Each theme brings new animations and something special when you complete a puzzle.
