Lucas is the friendly door into the Forty Thieves family. Before a single card is dealt to the table, all eight aces are lifted out and placed on their foundations. The remaining ninety-six cards deal into thirteen face-up columns of three, over a stock of fifty-seven. Nothing about the building rules is relaxed — it still builds down by suit, still one card at a time — but a board only three cards deep with every ace already up is a different proposition from ten columns of four and nothing started.
Do not bank a two just because you can. With the aces already up, the twos and threes are playable almost immediately, and that is the trap. Sending a two to the foundation when its three sits under an unmovable king strands the whole suit. Check what is above the next card before you play the current one.
Empty a column early — you have thirteen. Spaces are cheaper here than anywhere else in the family, and a space is the only way to re-home a blocker in a suit-only game. Clearing one three-card column costs little and pays for the rest of the deal.
Work the board fully before each stock click. There is no redeal, so the stock is a one-way street. Every card you pass is a card you will not see again.
Watch both copies of a rank. Two decks mean two of every card. If one nine of clubs is buried six deep and the other is on top of a column, the second one is your card — do not spend moves excavating the first.
The Forty Thieves group is one of the largest variant families in patience, and its members differ along a small set of dials: the deal shape, whether the tableau builds by suit or by colour, whether runs may travel, and whether the stock comes round again. Lucas turns a dial none of the others touch — it starts the foundations for you. Every other member makes you dig eight aces out of the pack before a foundation can begin, which is where most deals are lost. Removing that hurdle, and dealing only three cards deep, makes Lucas the family's gentlest introduction while leaving its strict suit-only building completely intact. Play it first, then Limited, then the parent, and you can feel each concession being taken away.
