玩法说明与常见问题How to play & FAQ
「蜘蛛纸牌」怎么玩？How do I play Spider Solitaire?
用两副牌共 104 张，10 列发牌。可以把任意牌接到大 1 点的牌下面；同花色、连续递减的一串牌可以整体移动。凑成同花色从 K 到 A 的完整一列会自动收走，收齐 8 列即获胜。没有可走的牌时点牌堆发牌（每列各发一张，发牌前不能有空列）。Two decks (104 cards) are dealt into 10 columns. Any card can go on a card one rank higher; a same-suit descending run can be moved together. A full same-suit run from King to Ace is removed automatically — clear all 8 to win. When stuck, deal a new row from the stock (one card per column; no column may be empty).
三种难度差别大吗？How different are the suit modes?
单色只有黑桃，最容易通关；双色有黑桃和红心；四色使用全部花色，同花色整串更难凑，难度最高。1 suit uses only spades and is the easiest; 2 suits mixes spades and hearts; 4 suits uses all suits and is much harder.
分数怎么计算？How is the score calculated?
开局 500 分，每走一步（包括发牌和撤销）扣 1 分，每收走一列加 100 分。You start with 500, lose 1 per move (including deals and undos) and gain 100 for each completed run.
