Two-suit spider solitaire played in the dark, hidden cards never turn over by themselves, so you weigh the odds and decide when to gamble on what's underneath.

How to play
Build columns downward by suit and remove a full King-to-Ace same-suit run; clear all eight runs to win. Unlike ordinary patience, face-down cards stay dark even when exposed at a column's base, they only reveal when you choose to commit one or spend a limited scry peek.
Move a revealed same-suit run with a click on its top card, then a click on the destination column.
Click a dark card to COMMIT it, flipping it sight-unseen, gambling on the odds.
Spend a Scry to safely peek a hidden top card, and use Deal Row to drop a card on every column when none are empty.
The Odds panel tracks how many copies of each card are still unseen, so you can compute the chance a hidden card helps.
Controls
Desktop: click a card or run to select, click a column to move there, click a dark card to commit, and use the toolbar for Scry, Deal Row and Undo.
Phone & tablet: the same taps work on the touch-friendly card table.
Game modes
Daily: one shared seeded deal per day to compare against others.
Practice: deal a fresh random game whenever you like.
Tips & strategy
Check the unseen-card distribution before committing, when most remaining copies help you, the gamble is worth it.
Hoard your scry peeks for high-stakes moments where a wrong flip would strand a column.
Empty a column when you can; any card can move onto an empty space, giving you room to untangle runs.
