Whitehead deals the staircase every Klondike player knows — seven columns growing from one card to seven — and then turns every card face up. Nothing is concealed, spaces accept any card, and packed runs travel as a unit. Three of Klondike's four difficulties are lifted at once. What it takes back is the building rule: Whitehead builds down in the same colour, which is stricter than Klondike's alternating colours, not looser. A red seven has two hosts here, and they are the two reds you also want to keep together.
A lost deal here is a deal you misplayed. With every card visible from the first click there is no luck left in what you can see — only in the order the stock will hand you the rest. That changes how you should play: look before you move, because the information to plan two or three moves ahead is genuinely there, which is almost never true in Klondike.
Same colour is the constraint, not the concession. Players arriving from Klondike routinely try to drop a black seven on a red eight and find it refused. Count your hosts before you commit: every card has exactly two possible landing places in the whole tableau, and they are both the same colour as itself.
Spend a space on a run, not on a card. An empty column takes anything, so its real value is as a destination for a long packed sequence you need to move off a low card. Filling it with a single stray card is the most common way to lose a winnable board.
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. Exhaust every free tableau move first.
The Klondike family is the largest in patience, and its members turn a handful of the same dials: how much of the staircase is hidden, what the tableau builds on, what an empty column accepts, how many cards a stock click turns, and how often the stock comes round again. Klondike itself sets most of them hard. Whitehead turns three the friendly way — nothing hidden, any card fills a space, runs move — and one the hard way, tightening the build from alternating colours to same colour. The result is not an easy game so much as an honest one: a pure-information puzzle where the deal is not hiding anything from you.
