Streets and Alleys is Beleaguered Castle without the head start. The Aces go into the shuffle with everything else, so before you can build anything, you have to find a way to reach them.
As in Beleaguered Castle, every card is visible from the start, and only your planning stands between you and a win.
All 52 cards are dealt face up into eight columns. The first four columns get seven cards each and the last four get six.
Move all 52 cards to the foundations. Once the remaining cards can all go up in order, the autocomplete button finishes the game for you.
We ran our own solver on 200 shuffled deals of this version. It found a win in 7 of 200 (4%), showed that 81 could not be won, and ran out of its budget of 20,000 positions a deal on 112.
Those undecided deals may still be winnable, so treat the win count as a minimum. The solver can see every card, including face-down ones, so it measures what the cards allow, not how often a person will win.
