Hold the lowest total. You have four cards face down. You look at two of them once, at the start. After that, remembering is the game.

Your turn: one of three
Tap the pile, then one of your cards: you take the card on the pile, your card goes on the pile.
Tap the deck, then one of your cards: you keep the card you drew.
Tap the deck, then Discard: if the card has a power, you may use it.
Powers (only for a card drawn and discarded at once)
Cut, at any moment
If you hold a card of the same rank as the card on top of the pile, drag it onto the pile, on your turn or not: it is gone. If it does not match, everyone sees it, it goes back, and you receive a card. You can also press Cut and tap a card.
Gobo
On your turn, say Gobo if you think you hold the lowest total. Everyone else plays one more turn, then all hands are shown. Lowest or tied: minus 5. Otherwise: plus 5. The game ends when a running total reaches the limit; the lowest total wins.
