In this beautifully elegant digital version, you can select up to 8 different cards, randomly selected from a collection curated and prepared by Eni herself. You can save different raffle selections and even search to easily find your favorite cards. LEARN SO MUCH MORE WITH EACH CARD But that's just the beginning, this digital version does so much more than the traditional game.

The game is so soothing and addictive you'll find yourself perusing the cards randomly just to learn more about each card!

ReceptionRating · Positive reviews · Number of ratings

Art Raffle holds the better App Store score, 5.0 against 4.8.

Written reviews complicate that: 98% of Art Raffle's written reviews are positive against 100% of Moiré / Interference's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Art Raffle ships an update every 5 weeks, Moiré / Interference every 19 months. The most recent releases landed on July 3, 2026 and September 22, 2026 respectively.
