A deal for today
The displayed challenge date identifies the daily set you are playing. Daily Challenge on sibaotong.com offers one dated Spider deal for each supported suit count. A daily deal uses the standard 104-card Spider rules. Choose one suit, two suits or four suits using the game controls.
The challenge clock
Here are the details for this mode. Your device's local date can differ from the challenge date near midnight. A new calendar day in the challenge timezone produces another set of deals. This website uses America/New_York to determine its challenge date. The date shown beside the controls is the date used for the current deal.
Return to a familiar layout
The following details apply here. The challenge date and selected suit count determine the starting shuffle. Loading the same date and suit count reproduces that starting layout. Different suit settings are separate daily challenges. The daily shuffle is not selected from the verified winning-deal collection.
Complete eight runs
The following details apply here. A mixed-suit sequence does not count as a completed run. A full face-up sequence is collected automatically at the bottom of a column. Clear eight same-suit sequences from King down to Ace to win. The run counter records your progress toward clearing all 104 cards.
Standard Spider movement
A few details help explain this feature. An empty column accepts any legal movable group. A group moves together only when its cards descend in one suit. A single exposed card can land on a card exactly one rank higher, regardless of suit. A King needs an empty column because no higher rank can receive it.
Use the stock
The following details apply here. Each stock deal places one face-up card on all ten columns. Every column must be occupied before you can deal from the stock. The daily table begins with fifty cards in the stock. New stock cards can both create useful moves and interrupt existing sequences.
Pause and return
Here are the details for this mode. Saved daily positions belong to this browser profile and domain. Returning to the same challenge can restore that saved position. Loading a new day's challenge replaces the saved daily position for that suit setting. With saving enabled, the browser stores your current daily game for each suit setting.
Continue across midnight
A date change displays a notice without replacing the cards you are playing. An open daily game checks periodically for a changed challenge date while the page is visible. Completing an older open game records the date attached to that game. The Today's challenge control loads the current day's deal.
Track daily completions
Keep these points in mind. Winning the same dated challenge repeatedly counts as one distinct daily completion. A completed challenge is also recorded by its date and suit count in this browser. My Statistics shows daily starts and wins separately for each suit setting. The local completion record is not a public leaderboard or an account-based history.
Options for another attempt
Here are the details for this mode. Undo can reverse a successful card move or a stock deal while history is available. Replay starts the same daily layout again. Use Winning Deals when you want a starting position with a checked complete solution. Hints offer legal moves without guaranteeing a route to victory.
