什麼是 Queens 解題器?

Queens 解題器會根據彩色區域以及已輸入的皇冠或 X 完成棋盤。它檢查每列、每行、每個區域的皇冠數,以及皇冠不可相鄰的規則。

此頁面對應 Queens solver、crown puzzle solver、Queens helper、Queens next move、一皇冠、二皇冠與三皇冠等搜尋需求。

  • 解 App、書本或列印紙上的 Queens。
  • 檢查目前皇冠與 X 是否仍有效。
  • 只顯示下一個邏輯步驟,不揭露完整答案。
  • 測試自製區域是否唯一解。

如何使用此解題器

先選擇大小與皇冠數。在區域模式中選顏色並塗滿棋盤。在皇冠 / X 模式中,將格子設為空白、X 或皇冠。

Solve 會完成謎題。Check 會確認輸入是否仍符合某個有效解。Next move 會顯示候選格,並標出強制皇冠或強制 X。

  • 可從空白棋盤手動複製題目。
  • 可載入範例快速試用。
  • 每個區域顏色至少要出現一次。
  • 輸入的皇冠視為固定線索。
  • X 會封鎖該格。

解題器使用的 Queens 規則

選 1 皇冠時,每列、每行與每個彩色區域都必須剛好有 1 個皇冠。選 2 或 3 皇冠時,數量也變成 2 或 3。

皇冠不可水平、垂直或斜角相鄰。

  • 每列有指定數量的皇冠。
  • 每行有指定數量的皇冠。
  • 每個區域有指定數量的皇冠。
  • 皇冠不可相鄰,包含斜角。
  • X 表示該格不可放皇冠。

下一步邏輯與 Queens 策略

Next move 會先建立候選圖,移除 X、已知皇冠周圍格,以及無法滿足計數的格子。

接著它尋找所有有效解都成立的步驟:若某格一定是皇冠,就是強制皇冠;若某格永遠不是皇冠,就是強制 X。

  • 猜測前先數列與行。
  • 查看剩餘空間少的區域。
  • 放下皇冠後排除周圍格。
  • 多皇冠模式要仔細計算剩餘數。
  • 若沒有強制步驟,可用 Solve 完成搜尋。

為什麼 Queens 可能無解

若某列皇冠太多、皇冠相鄰、區域可用格不足,或 X 封鎖所有必要位置,就可能無解。

自製 Queens 也可能有多個解。解題器會提示這種情況,方便調整區域或線索。

Queens solving techniques

These are the main ideas used by the next move helper. They also make good manual Queens strategy when you solve crown puzzles on paper.

Candidate Map

Beginner

The solver checks every row, column, region and no-touching rule, then marks the cells that can still hold a crown.

Forced Crown

Beginner

If every valid solution places a crown in the same square, that square is a safe next move.

Forced X

Beginner

If no valid solution can use a square, the solver can mark it with X without revealing the whole answer.

Row and Column Count

Beginner

Each row and column must contain the selected number of crowns, so full lines eliminate the remaining cells.

Region Count

Beginner

Every coloured region needs the selected number of crowns. When the possible cells are exhausted, the remaining moves are forced.

No-Touching Rule

Beginner

A crown blocks the eight surrounding cells, including diagonals, which is often the quickest Queens deduction.

FAQ

Queens 解題器常見問題

Can this Queens solver show just the next move?

Yes. Use Next move to show candidates and one forced crown or forced X. Use Apply move only when you want that hint added to the grid.

What grid sizes are supported?

The solver supports 5x5 to 9x9 for 1 crown, 8x8 to 10x10 for 2 crowns, and 12x12 or 13x13 for 3 crowns.

How do I enter the coloured regions?

Switch to Regions mode, choose a colour from the palette, and paint cells until the grid matches your Queens puzzle.

Is this a LinkedIn Queens solver?

It solves the same style of coloured-region crown logic puzzle, as long as the rule set is rows, columns, regions and no touching crowns.

Why does the solver say multiple solutions?

The current regions and marks allow more than one valid crown layout. The shown answer is valid, but the puzzle is not yet unique.
