空当接龙难关

空当接龙可说是最耐玩的Windows小游戏之一，尤其在办公一族中长盛不衰。Win98中的空当接龙有32000局，在XP里面则增加到了 1000000关，不过前32000关与Win98的是一样的。在空当接龙的帮助文件中，作者Jim Horne 称：“虽然未经证明，但请您相信：所有的牌局最终都能移开。”事实究竟如何，是一个非常有趣的话题。

首先，两个隐藏关-1, -2关一定是无解的，除了这两关，还有八局是无解的，它们分别是第11982, 146692, 186216, 455889, 495505, 512118, 517776, 781948局。

上面十关就不要去试了，喜欢挑战自我的可以来试一下这些关：1-10, 21, 63, 68, 76, 86, 92, 96, 110, 123, 169, 170, 178, 190, 194, 237, 258, 285, 322, 385, 454, 518, 527, 575, 598, 617, 657, 669, 693, 718, 723, 770, 792, 798, 828, 829, 846, 865, 868, 877, 901, 912, 915, 1025, 1072, 1136, 1150, 1256, 1285, 1314, 1381, 1445, 1483, 1652, 1689, 1734, 1941, 2021, 2081, 2240, 2350, 2405, 2577, 2607, 2670, 2772, 2884, 2902, 3099, 3112, 3199, 3202, 3285, 3289, 3294, 3328, 3342, 3349, 3393, 3426, 3467, 3631, 3685, 3699, 3772, 3788, 3801, 3973, 4074, 4089, 4257, 4368, 4467, 4518, 4538, 4540, 4556, 4560, 4591, 4609, 4714, 4794, 4813, 4946, 5179, 5225, 5265, 5374, 5412, 5453, 5468, 5482, 5490, 5548, 5557, 5851, 5979, 6182, 6240, 6247, 6343, 6505, 6581, 6589, 6673, 6693, 6745, 6751, 6768, 6775, 6801, 6834, 6918, 7000, 7107, 7160, 7239, 7303, 7305, 7354, 7477, 7485, 7600, 7660, 7700, 7825, 7851, 8005, 8122, 8323, 8354, 8454, 8591, 8652, 8678, 8711, 8726, 8732, 8749, 8811, 8820, 9209, 9250, 9385, 9457, 9538, 9617, 9700, 9718, 9787, 9830, 9885, 10302, 10509, 10589, 10623, 10660, 10692, 11114, 11150, 11281, 11386, 11409, 11430, 11677, 11767, 11854, 11873, 11987, 12211, 12220, 12249, 12271, 12277, 12286, 12313, 12319, 12330, 12384, 12795, 12949, 13007, 13015, 13228, 13304, 13388, 13506, 13550, 13551, 13583, 13584, 13612, 13752, 13765, 13867, 13996, 14051, 14070, 14084, 14133, 14188, 14262, 14548, 14580, 14621, 14666, 14676, 14759, 14795, 14879, 14965, 14977, 15023, 15099, 15130, 15133, 15164, 15227, 15238, 15377, 15396, 15512, 15562, 15710, 15746, 15905, 15939, 16129, 16191, 16202, 16508, 16575, 16576, 16768, 17277, 17426, 17467, 17524, 17680, 17683, 17708, 17764, 17768, 17863, 17985, 18446, 18492, 18512, 18623, 18872, 18906, 18992, 19146, 19152, 19410, 19425, 19431, 19444, 19482, 19484, 19497, 19590, 19626, 19633, 19763, 19837, 19861, 19880, 20055, 20251, 20411, 20418, 20426, 20547, 20581, 20589, 20630, 20703, 20715, 20830, 20873, 20912, 21042, 21051, 21185, 21262, 21278, 21283, 21322, 21365, 21491, 21587, 21785, 21896, 21899, 21927, 21944

如果你觉得上面的太多了，你想直接挑战一下最难的，那就直接试试第617, 1941, 8591, 3007, 31465, 31938关吧，因为“Laura Ross of Omaha, Nebraska played all 32,000 deals, solving all but five of the deals (8591, the impossible 11982, 13007, 31465, and 31938 ). She found 617 and 1941 the most difficult of those she solved. ”
