Solitaire

My record

The goal is to move all 52 cards to the four foundations at the top right, one suit each, from Ace up to King.
In the seven tableau columns, build down by one rank in alternating colors (for example, a red 7 on a black 8).
A face-up card can be moved together with all the cards on top of it.
Only a King (or a run starting with a King) can go into an empty column.
Tap the stock at the top left to turn over 1 card (or 3). When it runs out, you can go through it again.
