Clueless Explosion Archive - Ruud's Puzzles This is an archive of Ruud's Clueless Explosion puzzles and solutions, which were originally posted on sudocue.net from 2006 to 2008. The ratings are those quoted by Ruud when he posted his puzzles. For those who aren’t familiar with Clueless Explosions, the 81 blue cells form an extra Sudoku grid. This form of Sudoku is called Clueless because the blue cells don’t include any numbers (clues). There are diagrams for each puzzle and solution. Alternatively, if you are using a software solver, there are code strings. If you are using SudokuSolver first select File, Puzzle Type -> Extended; then in the Puzzle Type drop down menu below the right-hand diagram select Clueless Explosion. Now Select the Code String and Copy and Paste into SudokuSolver. Other software solvers will have similar procedures. Edit. I've now found that there's a simpler way using SudokuSolver. Select File, Import, Explosion, copy and paste the code string into the new window that opens and click OK. There wasn't a specific Clueless Explosion guide, but Ruud's Clueless Special guide may give useful hints about how to get started. Puzzle rating table, with links to archive entries. At Ed's suggestion, I've added SudokuSolver(v3.6) scores to the table. A score of 0.85 indicates that SS solved these puzzles using hidden singles and box/line intersections, scores of 0.95 and 1.00 are when SS used hidden singles, hidden pairs and box/line intersections, higher scores indicate the use of harder techniques. +-----------------------+------------+-------+ +-----------------------+------------+-------+ +-----------------------+------------+-------+ +-----------------------+------------+-------+ +-----------------------+------------+-------+ +-----------------------+------------+-------+ +-----------------------+------------+-------+ +-----------------------+------------+-------+ +-----------------------+------------+-------+ Roll of Honour Ruud wrote: For each correct Clueless Explosion, you earn 1 point. Note: To enable new players to catch up with the regulars, only the last 26 Clueless Explosions will included in the score. On Ruud's website, players with 26 points were shown with a gold medal, those with 25 points a silver medal and a bronze medal for those with 23 points. +----+-------+--------------------------+-------------+-------+ +--------------------+-------+---------+---------+ There was also a list for each of the last 26 puzzles of the order in which correct solutions were submitted. There were between 25 and 34 correct solutions submitted for each of these puzzles. |
