The four Aces begin in the central towers. The other 48 cards form 8 rows of 6 — the castle walls besieging the towers.

Only the exposed card at the end of each row may be played.

Move it to a tower if it's the same suit and next in sequence (2♦ on A♦, then 3♦…).

Or onto the exposed end of another row, if that card is one higher — suit doesn't matter (any 4 on any 5).

Or into an empty space where a row has been completely cleared.

Object: complete all four towers Ace to King in suit.

Tap a card to move it automatically, or drag it precisely. ✨ sends every possible card home to the towers.

Each new siege unfolds in one of ten realms — from Narnia's lamppost and Stonehenge to Clarke's monolith, Earthrise and space elevator.
