Alaska belongs to the Yukon family: there is no stock, every card is dealt at the start, and you can pick up any face-up card along with everything on top of it.
What sets it apart is direction. Russian Solitaire builds down in suit, while Alaska lets you build up or down in suit, so a 9 of diamonds can go on either the 8 or the 10 of diamonds. That gives you far more moves to choose from, and more ways to tangle a column.
All 52 cards are dealt into seven columns. The first column holds one face-up card. The other six hold from one to six face-down cards, each with five face-up cards on top. Four empty foundations wait above.
Move all 52 cards to the foundations. Once every card is face up and the rest can 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 86 of 200 (43%), showed that 8 could not be won, and ran out of its budget of 20,000 positions a deal on 106.
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.

Yes. Any face-up card can move with everything on top of it, as long as the card you pick up is one rank away from the target card and in the same suit.
No. Only a King, or a group that starts with a King.
