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 7 cards. In the first four Columns, the first 3 cards are dealt face down - the Scorpion's tail. All other cards are dealt face up. Three cards will remain in the Stock.
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.
The goal is to build 4 sets of cards within the layout from King down to Ace in the same suit. 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.
3 cards will remain in the Stock after the deal. When play comes to a standstill (or sooner if desired,) clicking on the Stock deals it's 3 cards one each to the first three Columns.
