玩Duplex

规则

  1. 未涂色
  2. 涂色
  3. 尚未确定
  4. 在划分成区域的网格中涂色。
  5. 两块多米诺绝不共用一条边。在角上相碰是允许的。
  6. 游戏中会标出两种错误：涂色格过多的区域，以及与两个或更多涂色格相邻的涂色格。还缺的则不会标出——不足两个的区域、没有搭档的涂色格——所以棋盘上没有红色并不一定意味着已经解开。
  7. 点按格子涂色，再按一次标为未涂色，第三次清除。拖动可标记一段。
  8. 我知道了
  9. 每个区域恰好包含两个涂色格。
  10. 每个涂色格恰好有一个涂色的相邻格，因此涂色格会两两并排成对：多米诺。多米诺可以跨过区域边界。
  11. 每道题都恰好只有一个解。

关于这款游戏

Duplex is a Norinori puzzle for players who like unhurried, honest logic. The name means "twofold", and the rule is exactly that: every region holds two.

The grid is cut into regions. Shade cells so that every region ends up with exactly two shaded cells, and so that the shaded cells come as dominoes: every shaded cell touches exactly one other shaded cell, side by side. A domino may cross a region border, but two dominoes never share an edge. Tap a cell to shade it; press and hold to mark it unshaded.

One solution, every time

Every puzzle has exactly one solution, checked by a solver before it ships. The hint button uses that same solver: it shows the next step the board allows, and says which idea it used.

Learn it by playing it

The walkthrough hands you real positions and asks for the one cell that follows, then shows you why. Five ideas carry you a long way: a region that has only two cells, a region that already has its pair, a domino that is complete, a shaded cell with only one possible partner, and a cell that can never find one.
