Whitehead starts from the Klondike layout and turns it around. Every card in the columns is dealt face up, so you can plan from the first move, and red cards build on red while black builds on black.
Building by color gives you plenty of places to put a card, but runs only move together when they are all one suit. A 6 of hearts on a 7 of diamonds is a legal build that can't travel as a group, and that is what makes the game tricky.
Twenty-eight cards are dealt face up into seven columns of one to seven cards. The other 24 cards form the stock, and the four foundations start empty.
Move all 52 cards to the foundations. Once the stock and waste are gone, autocomplete can finish the game when the rest go up in order.
We ran our own solver on 200 shuffled deals of this version. It found a win in 56 of 200 (28%), showed that 4 could not be won, and ran out of its budget of 20,000 positions a deal on 140.
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.
Love Whitehead? Try these other solitaire variants on Solitaire Scramble:
All the column cards start face up, columns build by the same color rather than alternating, only one-suit runs move together, any card can fill an empty column, and there is one pass through the stock.
The whole group has to be in one suit. A run like the 8 of hearts, 7 of diamonds and 6 of hearts is legal to build, but it has to be moved one card at a time.
Yes, any card, or a run in one suit.
No. This version gives you one pass, drawing one card at a time.
