路线画风 · 审查台

+

这里画的是轨道本身，不是关卡。先看线好不好看，再谈难度——因为线是玩家一眼就会看到的东西。

+

载入中…

+ +
+

「直穿填充」是那些满屏直线的来源。每个家族只铺自己的签名路线，盘面剩下的端口由填充逻辑配对，而它默认配成对穿的直线。一个格子里两条直线必定相交，所以直线多 = 交叉点多，两件事是同一个原因。

+

它还在压制反差。换成偏好弯道之后，花瓣的反差从 4.2 升到 14.0、双叶跨区从 4.8 升到 28.8、环绕从 10.6 升到 22.9 —— 前两个家族原本是被「反差 ≥12」这道闸门挡在关卡池之外的，其中花瓣正是「像花一样」的那个。
（反差要在盘面上摆好棋子、长成关卡之后才测得出来，所以不在下面这张表里；这几个数字来自六个种子的构造结果。）

六个家族的画风

+

同一个种子、同一个底板，只换填充方式。数字越低越好：直线占比是对穿轨道占全部轨道的比例，交叉/格是每个格子里互相穿过的轨道对数。

当前交付的 50 关

这是现在能玩到的那 50 关的盘面，用同一套指标标注。标红的是直线占比超过 60% 的。
