连续数独 Consecutive
标准数独基础上，挡板两侧数字连续，相邻两格之间如果没有挡板，则这两格一定不连续。
Classic rules applied. Additionally, the 2 numbers adjacent to the bar is consecutive, 2 adjacent cells with no bar cannot be consecutive.
在一些描述里，规则是：标准数独基础上，挡板两侧数字连续，符合条件的情况被全部标记。这种描述被称为全标，意味着没有标记的任何地方都不符合标记的要求。
In some description, the rule is: Additionally, the 2 numbers adjacent to the bar is consecutive, all conditions are marked. This is called full-marked, it means anywhere no mark must do not obey the rules.
在连续数独中，至少应该有1个已知数。如果N阶题目中，N是奇数，那么这个给定的已知数不是（N-1）/2。
There should be at least one number in Consecutive. If N is odd in NxN puzzles, the unique given number cannot be (N-1)/2.
在接下来的例子中，灰色区域内的挡板被全部标记，其他挡板可能没有给出。
In next examples, bars in grey zones are all given. Other bars may not given in white zones.
◆连续对 Consecutive Pairs
一个挡板两侧的数字构成一个连续对。如果一个连续对的一个数字已知，我们应当试图寻找另一个数字，也就是它的配偶。
Two numbers adjacent to one Bar is a Consecutive Pair.If a number in Consecutive Pair is known, we should try to find the other one, we called it as Couple.
① 如果一个连续对里有1，则它一定有2。同理N和N-1。
If a Consecutive Pair contains 1, it must contain 2 either. And also N with N-1.
② 如果某格的配偶不是2，则该格不是1。同理N-1和N。
1 cannot be in one cell when it's Couple is not 2. And also N with N-1.
③ 如果某格的配偶不是X+1和X-1，则该格不是X。
X cannot be in one cell when it's Couple is not X+1 and X-1.
◆长连续 Long Consecutives
至少三个不同的格子，被挡板连起来，构成长连续。
At least 3 different cells conbined by bars form a long consecutives.
① 长连续有方向 Long consecutive has directions.
② 六阶数独中，四格的长连续必须有3和4。
4-cell long consecutive in 1~6 must contain 3 and 4.
③ 如果长连续里没有2，则1不能在长连续内。
1 cannot be in long consecutives without 2.
④ 长连续分组 Groups of long consecutive
下图中，已知数3将1~6分成了1+2以及4~6两组。The given 3 seperate 1~6 into 1+2 and 4~6.
◆奇偶性 Parity
挡板两侧的数字必定是一个奇数和一个偶数。我们可以对奇偶单元格进行计数，尤其是在长连续的分析里。
Adjacent cells with a bar must be one odd and one even. We can count odd and even cells, especailly in long consecutives.
◆六阶同区三组 3 groups a region in 6x6
一个区域内有三组不同的连续对，必定是12/34/56组合。
Three groups of different Consecutive Pairs in one region, they must be 12+34+56.
◆无挡板结构Structure without bars
① 两个相邻格有A Two adjacent cells with A
It cannot contain A+1 or A-1.
② 三个不同的相邻格有A Three adjacent different cells with A
The center cannot contain A+1 or A-1.
◆以下这些技巧在不连续数独中更为常见。
These next ways are more often seen in Non-consecutive.
◆有挡板结构 Structure with bars
① A1≠2. ② C2≠2.
③ 无论3在哪里，都有B2=4。Wherever 3 is, B2=4.
④ EF5=[5,6].
◆2x2不连续方 Non-consecutive in 2x2 squares
2x2不连续方是2x2的区域，其内部没有任何挡板。
Non-consecutive in 2x2 squares is a 2x2 square with no bars inside.
① 这种区域不包含三连数（如234或者678）。
3-combined consecutives (such like 234 or 678) cannot be in.
② 四连数（1234或6789）不能同时在0个或2个挡板的2x2区域之中。
4-combined consecutives (such like 1234 or 6789) cannot be all in a 2x2 square with 0 or 2 bars.
练习 Practice A
① 第一宫有一个长连续占据了四个单元格。它们都不能是6，那么它们之中一定有______。
A long consecutives in Box 1 occupies 4 cells. All of them cannot be 6, they must contain ______.
② 四阶连续数独中是否能有一个宫没有挡板？
In 4x4 Consecutive, can there be a box without bars?
③ 填完灰色区域 Fill the grey cells.
答案 Answer A
① 2~4 ② No ③ As the picture.
练习 Practice B
① 寻找灰色区域内的下一步 Find the next step in grey zones.
② 在这道连续中，第八宫的1应该在______，G5=______。
In this Consecutive, Hidden Single 1 in Box 8 should be in ______, G5=______.
③ 解答问号格 Find the ？cells.
答案 Answer B
① H5≠6, G5=6; H9=8, I9=9. ② H4; 8.
③ A3=5; C4=9;
C6=2 (C5≠2, otherwise no number in B5);
B5=1(Hidden Single in Row B), C4=2, D4=3.
