Josephine deals the classic Forty Thieves board — two decks, ten columns of four cards, everything face up — and changes exactly one rule: a packed sequence may be moved as a unit. In the parent game every card has to be carried across one at a time, which is what makes an assembled run there a liability rather than an asset. Here a run is a tool you can pick up. It sounds like a small mercy, and against most of this family it is: the sequences still have to be built by suit, and a same-suit run is far rarer than an alternating-colour one.
Build runs on purpose, but do not chase them. The run rule only pays when a sequence actually forms, and same-suit sequences do not form by accident. When you have a choice of hosts, take the one that extends a run you can imagine moving later. When you do not, do not contort the board trying to make one.
An empty column is worth far more here than in Forty Thieves. In the parent a space accepts one card. Here it accepts an entire staircase, which is the only way to relocate a long sequence in one move. That makes clearing a column the highest-value project on the board — and refilling it casually the most expensive mistake.
Dig for aces and twos above everything. Two decks mean every rank appears twice, so a buried ace is survivable. A suit whose ace and two are both deep will stall both of its foundations, and with no redeal there is no second pass to free them.
Play the board out before every stock click. One pass, one card at a time, no way back. A card you skip is a card you will never see again, so exhaust every free tableau move first.
The Forty Thieves group varies along a handful of dials: how much of the board is hidden, whether you build by suit or by colour, whether runs may travel, and whether the stock comes round again. Most members turn one dial away from the parent's hardest setting. Josephine is unusual in turning the run dial while leaving the build on suit — a combination no other common member has. Rank and File moves runs but builds by colour; Streets builds by colour without runs; Forty Thieves does neither. Because same-suit runs are scarce, Josephine ends up closer to the parent in difficulty than Rank and File is to Emperor, which makes it the natural next game once Forty Thieves stops feeling impossible.
