🔵 二进制数独Binary Puzzle
在线二进制数独（0/1 谜题）：在方格里填 0 和 1，同一行或同一列不能有三个相同的数字连在一起，每行每列 0 和 1 的个数各占一半，而且任意两行、任意两列都不能完全相同；6×6、8×8、10×10 三种尺寸和三档难度，每题唯一解，带行列计数、冲突提示、撤销和提示。Play the binary puzzle online: fill the grid with 0s and 1s so no three identical digits sit next to each other in a row or column, every row and column has as many 0s as 1s, and no two rows (or columns) are identical. Three sizes (6×6, 8×8, 10×10) and three levels, unique solutions, row/column counters, conflict highlighting, undo and hints.
点空格依次填 0（蓝）→ 1（黄）→ 清空，右键反向切换；也可以选中格子后按键盘 0 / 1，Backspace 清空，方向键移动，U 撤销。带小白点的是题目给定的格子。右边和下边的“3·2”表示这一行（列）已有 3 个 0、2 个 1，数量正好一半时变绿。Tap an empty cell to cycle 0 (blue) → 1 (yellow) → empty; right-click cycles the other way. Or select a cell and press 0 / 1, Backspace to clear, arrows to move and U to undo. Cells with a small white dot are givens. The “3·2” counters on the right and bottom show how many 0s and 1s a line has; they turn green when it is exactly half and half.

「二进制数独」怎么玩？How do I play Binary Puzzle?
规则只有三条：① 同一行、同一列里不能出现三个连续相同的数字（例如 0 0 0）；② 每一行、每一列里 0 和 1 的数量相等；③ 不能有两行完全一样，也不能有两列完全一样。根据规则①，两个相同数字的两端，以及“0 _ 0”中间的空格都可以立刻确定；某一行的 0 已经够一半时，剩下的格子就全是 1。There are just three rules: (1) no three identical digits in a row in any row or column (like 0 0 0); (2) every row and column has equal numbers of 0s and 1s; (3) no two rows are identical and no two columns are identical. Rule 1 immediately settles the cells on either side of a pair and the gap in “0 _ 0”; once a line has its quota of 0s, the rest must be 1s.
“两行不能相同”什么时候用得到？When does the “no identical lines” rule matter?
通常在最后阶段：如果某一行只剩两个空格，而它已填的部分和另一行完全相同，那么这两个空格必须填成和那一行相反的顺序。这是高难度题目里经常需要的一步。Usually near the end: if a row has two empty cells left and its filled cells match another completed row exactly, those two cells must be filled the opposite way round to that row. Hard puzzles often need this step.
这个游戏和二进制有关系吗？Is it really about binary numbers?
只是借用了 0 和 1 两个数字，不需要会二进制运算。它也常被叫作 Takuzu 或二进制数独，本质是一种排除法逻辑谜题。It only borrows the digits 0 and 1 — no binary arithmetic is involved. It is also known as Takuzu or binairo, and at heart it is a pure logic-elimination puzzle.
