🌊 颜色填充Color Flood
在线颜色填充（洪水填色）游戏：从左上角开始，每次选一种颜色，把相连的同色区域染成它并吞并周围同色格子，在限定步数内把整个棋盘染成一种颜色；三种尺寸、4/6/8 色可选，带提示和最少步数记录。Play color flood online: starting from the top-left corner, pick a colour each turn to repaint your connected region and absorb neighbouring cells of that colour — fill the whole board with one colour within the move limit. Three board sizes, 4, 6 or 8 colours, hints and fewest-move records.
白线圈住的是你已经占领的区域（从左上角开始）。点下面的颜色按钮，或直接点棋盘上任意一格，你的整片区域就会变成那种颜色，并把相邻的同色格子吞进来。在步数用完之前把整个棋盘变成一种颜色就赢了。键盘：数字 1–8 选颜色，H 提示，N 新游戏。The white outline marks the region you own, starting at the top-left corner. Press a colour button — or click any cell of that colour — and your whole region turns that colour, absorbing adjacent cells that match. Make the entire board one colour before you run out of moves.

玩法说明与常见问题How to play & FAQ
「颜色填充」怎么玩？How do I play Color Flood?
棋盘由随机颜色的小方格组成。你从左上角那一格开始，它和与它相连的同色格子组成“你的区域”。每一步选一种新颜色，整片区域都会变成这种颜色，于是和它相邻的这种颜色的格子也被连进来，区域越滚越大。在限定步数内（例如 14×14、6 色为 25 步）让全盘只剩一种颜色就成功了。The board is a grid of randomly coloured cells. You start from the top-left cell, which together with every connected cell of the same colour forms your region. Each move picks a new colour: the whole region changes to it and swallows the adjacent cells of that colour, so it keeps growing. Turn the whole board into a single colour within the move limit (25 moves on 14×14 with six colours) to win.
步数限制是怎么定的？How is the move limit set?
步数随棋盘大小和颜色数量变化：10×10/6 色 18 步、14×14/6 色 25 步、18×18/6 色 32 步，颜色越多步数越多。超过步数也可以继续把棋盘染完，只是这一局算失败。The limit grows with the board size and number of colours: 18 moves for 10×10 with six colours, 25 for 14×14 and 32 for 18×18. You can keep playing past the limit to finish the board, but the game counts as a loss.
有什么技巧？Any strategy?
别只盯着眼前能吞掉最多格子的颜色，优先朝棋盘中心和对角方向扩张，让区域边界变长，后面每一步都能吃到更多格子；「提示」会向前多看一步帮你挑颜色。Don't just grab the colour that captures the most cells right now — push towards the centre and the far corner first so your border grows longer and every later move captures more. Hint looks one move ahead to suggest a colour.
