Klondike, the one from the office computer. Build the four foundations up from ace to king, one suit each.
On the table, build down in alternating colors: a red six on a black seven. Move a card or a whole run by dragging it, or tap it and then tap where it goes. Tap a card twice to send it to the foundation, or to the first spot that will take it. Only a king can go on an empty column.
Tap the deck to turn cards over. When it runs out, tap it again to turn the pile back over.
Score the old-fashioned way: 10 for each card to a foundation, 5 for a card from the deck to the table, 5 for turning over a face-down card, and a penalty for taking a card back off a foundation or going through the deck too many times. Undo takes back as many moves as you like.

Sounds covers the card noises, and the slider next to it covers everything. Music plays soft ambient music. Night mode warms the screen for a dark room. Chill mode turns all three on for late nights. Every switch is remembered on this device.
