VelvetCell

A private card room after hours: green baize, brass fittings, and a deck laid out face up. Nothing is hidden in FreeCell. Every card you need is already in front of you — the only thing standing between you and the finish is the order they happen to be in.
Eight columns hold the deck. Four free cells park one card each when nothing else will fit. Four foundations wait for each suit to come home from the ace up. Build down in alternating colours, keep your cells open, and think two moves further than feels comfortable.
THIRTY DEALS, FOUR ROOMS
Start in the Oak Room on deals that come apart in a few dozen moves. Work through the Brass Room and the Garnet Room to the Midnight Room, where the aces sit buried six deep and every free cell you spend is one you will want back.
DEALS THAT WERE ACTUALLY CHECKED
None of the thirty were picked by eye. A solver played 320 shuffles to the end, threw out every one it could not finish and every one whose only line was absurdly long, and the deals that shipped were spread evenly across what survived — ordered by how much searching each one cost. Deal thirty is genuinely harder than deal one, and par is a line that has actually been played to the finish, not a guess. Beat par and you have beaten the machine.
THREE THINGS TO SPEND ON MID-DEAL
Read points out a move from a winning line.
Take-Back walks the table back three moves and takes those moves off your count with it.
Fifth Cell opens one more free cell for the rest of the deal.
FOUR TRACKS THAT STAY WITH YOU
Spend chips in the back room on upgrades that persist: sit down already holding a Read, keep a Take-Back in reserve, take a heavier payout from every deal you finish, or buy yourself room over par before the crowns start dropping.
