MerryWrap is an advent calendar you play. Behind every door is a fresh puzzle, one a day from December 1 to Christmas morning, and every player in the world gets the same board. HOW TO PLAY Each number on the board is a gift. Drag a rectangle that holds one number and covers exactly that many squares. Cover the whole board to finish. Easy to learn in one door, a real puzzle by the last week. THE RIBBON Every wrap spends ribbon equal to its outline, so a long thin box costs more than a square one. Early doors skip the ribbon, middle doors give you a little extra, and the last week gives you just enough. Shape is strategy. 25 DOORS, EACH ITS OWN WORLD Snowy nights, peppermint stripes, gingerbread icing, northern lights and more. Sundays and Christmas morning bring special shaped boards. One door opens each day, and open doors stay open, so you can always catch up. GIFT TAGS Every door hides a gift tag with a little Christmas message. Tear open your gifts after you solve to find it. Find it on your first tear and earn a candy cane. Your Album keeps every tag you find. FREE FOR EVERYONE Doors 1 to 5 of every year's calendar Three sample boards, any time Three free days in Santa's Workshop Christmas in July: twelve free doors, July 13 to 24, with summer colors and their own gift tags THE 2026 CALENDAR, ONE PURCHASE Doors 6 to 25 of the 2026 calendar Santa's Workshop: a new puzzle every day of the year, with a note from the elves hidden in each one Yours to keep, never renews Family Sharing: one purchase covers the household Each new year's calendar is its own purchase, only if you want it. No subscription, no ads, no account, no pop-ups. Nothing gets between you and the puzzle. Share a spoiler-free result card after every door you solve, keep your streak going, and turn on an optional daily reminder so you never miss a door. MerryWrap is an Apps That Help product.
