From the name, I'd guess something like: once you solve one grid, you need to copy and paste certain digits from that into another grid, and so on. But I'm just guessing- I hate it when they announce a test before the IB is ready, because I always hate the suspense! ![]() |

But it was after 5 hours of sudoku playing and trying to speak in German and English all day... So I don't remember what he said actually ![]() I hope there will not be too many irregular sudokus ![]() Fred |

Posts: 191 ![]() ![]() ![]() ![]() ![]() Country : The Netherlands | Richard posted @ 2012-06-24 11:13 AM After completing the Copy-Paste test, I had a few unused puzzles. I have posted them in the puzzle portal of Logic Masters Germany yesterday. Here are the links to the leftovers: Arrow Sum 100 Ascending Consecutive Minimax Maximin With exception of the Arrow sudoku, all of the puzzles above are a bit harder then the ones of the same type in the real test. Please look at my comment at the Arrow sudoku in the puzzle portal, explaining why I use a different lay out then the international standard. I hope my puzzle doesn't lead to too much confusion. |

The 4 is given in R9, so swapping digits is limited. The puzzle has definitely a unique solution. |

It's good that IB's appear and that forum threads are opened before a test is hold. ![]() |

It is interesting that Richard and Sylvain came up with similar ideas with few weeks apart (much before Clone round in BIST). Thats when we decided to schedule these 2 tests one week apart and to publish the IBs at the same time. Luckily, the variations in these 2 tests are very different and I'm sure players will enjoy these tests like every other LMI tests. |

If you hadn't done that already, maybe that helps. Edited by prasanna16391 2012-06-24 11:53 PM |

Just for my curiosity: is it an already published puzzle (perhaps from a previous year IB of DSM?), or have I dreamed it? ![]() Fred |
