Form four sets of cards of the same suit from King to Ace within the Columns.
Using one deck, each of seven Columns is dealt 3 cards. In the first four Columns, the first card is dealt face down; the Scorpion's tail. The other Column cards are dealt face up. All undealt cards will be in the Stock ready to be played at any time.
Columns are built DOWN in the SAME SUIT. For example, a 6 of clubs may only be placed onto a 7 of clubs.
Any number of face up cards may be moved whether in sequence or not provided the above build rule is applied.
When a face down card is the topmost card in a Column, it is flipped face up.
Empty Columns may be filled with Kings.
One point is scored for each card built within a Column starting with a King. For example, if a Column has a K, Q, and J of the same suit in sequence then three points are scored for that combination.
When play comes to a standstill (or sooner if desired,) clicking on the Stock deals one card to each Column.
