# Solitaire - credits and notes

**The game.** Klondike is the best known solitaire of all, and in North America "Solitaire" with no
qualifier means Klondike. The version bundled with Microsoft Windows from 3.0 (1990) to XP - written by
the intern Wes Cherry in 1988, with cards by Susan Kare - has been called the most played computer game
ever, and it fixed the details most players know: seven piles dealt one to seven cards with the top card
face up, a stock drawn one or three at a time, Standard or Vegas scoring or none, a timed game with a
bonus, a chooser of card backs (some animated), a single level of undo, and the cards bouncing down the
screen when you win.

**This recreation** (https://solitaire.skillsafe.ai/) is an independent browser implementation of that
game: the Windows layout and Win9x window with Game / Help menus and a Score / Time status bar; Options
exactly as the original (Draw one / Draw three, Standard / Vegas / None, Timed game, Status bar, Outline
dragging, Keep score, with a new deal when draw, scoring or timing change); Standard scoring of 5 / 10 /
10 / 5 / -15, -100 for turning the deck in Draw One and -20 after the third pass in Draw Three, -2 every
10 seconds when timed, a bonus of 700,000 / seconds for a timed win of 30 seconds or more, and a floor of
0; Vegas scoring with a $52 buy-in, $5 per card home ($5 back if retrieved), one pass in Draw One and
three in Draw Three, and Keep score carrying the total; Deal (F2), Undo (one level), Deck... with twelve
card backs (three animated), Options..., Exit, Help Contents (F1) and About; drag and drop with optional
outline dragging; double-click and right-click to a foundation (right-click on an open space sends every
card that can go, as in Windows 2000 and later); the Ctrl+Alt+Shift Draw One cheat; the bouncing-card
victory with trails and "Congratulations! Deal again?"; and no resign prompt, hint, auto-complete or loss
message, because the original had none.

Additions that the original did not have, labelled as such on the page: numbered deals with shareable
links (this page's own numbering, 1 to 1000000; #617-1 and #617-3 are the same layout at different draw
settings - not the numbering of any other program), click-then-click moves for touch screens, the game
in progress surviving a reload, statistics per draw setting (played, won, best score, best time,
streaks; cheated games excluded), Select Game (F3), Statistics (F4), Options on F5, Undo on Ctrl+Z, and
animated deals and moves that can be switched off.

Where the sources are silent we followed our own reading and say so on the page: the Standard score is
clamped at 0 for every deduction (the KB article states the floor for the recycle penalty); the timed
deduction runs from the first move; changing Timed game deals a new game like changing draw or scoring;
Vegas shows the time but has no time penalty or bonus; the exact key combination of the Draw One cheat.
