Spider Web starts with 24 visible cards across seven columns. Its reserve is a stack rather than a single-card cell: several cards can wait there, but only the top can leave.
The reserve reverses access to parked cards
Build tableau columns down by rank regardless of suit. Descending suited runs can move together, and any card or legal run fills an empty column. Add reserve cards one at a time in any rank order. The 28-card stock deals four rows of seven, with no redeal.
Park cards in an order you can undo
A card placed on the reserve covers every earlier card there. Check its exit before adding another blocker, especially when a buried reserve card completes a suit run. Win with four complete king-to-ace runs remaining in the tableau and an empty reserve and stock.
