How to play Pyramid solitaire
Twenty-eight cards form a pyramid of seven rows. A card is free when no card overlaps it from below. Tap two free cards that add up to 13 to remove them: Ace = 1, numbers count their value, Jack = 11, Queen = 12, and a King (13) goes on its own with a single tap. Pairs that work are A + Q, 2 + J, 3 + 10, 4 + 9, 5 + 8 and 6 + 7. Clear all 28 pyramid cards to win.
Stock and waste
Tap the deck at the top left to turn up its next card onto the waste pile. The top waste card can pair with any free pyramid card. When the deck is empty you can turn the waste pile back over and go through it again — twice in total, so you see the deck three times. Every deal is checked by a solver before you see it, so there is always a way to clear the pyramid.
Tips
Look ahead before you pair: when the same rank appears twice, remove the copy that frees more cards. Work on the bottom rows evenly so you are not left with one tall column. Hint follows a winning line from your current position, and undo works as many times as you like. Your best time is saved on this device.
