ZKPuzzle

ZKPuzzle, from Medici Collective Co, first came to the App Store in January 2024 and grew out of the maker's earlier Puzzle wallet app. It calls itself a daily puzzle, group chat and rewards app, and the puzzles are the reason to open it each morning, and the rest is built around them. Android? The website still says so, though its Google Play listing was gone in October 2026.

Each day brings a fresh numbered set of more than ten small games. The store pictures show Mystery City as the day's featured puzzle, with Wordle, Sudoku, Queens, Pips, Zip and Tiles among the others, so a day mixes a word guess with several logic grids of the kind LinkedIn and the New York Times have made popular.

The social side is a group chat with end-to-end encrypted messages, where your crew sees one another's scores on a daily leaderboard. Playing and keeping a streak earn points, which shops in the app turn into gift cards and giveaway entries (Chipotle, Uniqlo, Amazon and Uber are named). There are no ads; the app also offers referrals, walking rewards through Apple Health and a Puzzle Pro tier.

It suits a group of friends who already trade puzzle scores in a chat and would like the games, the scores and the chat in one place. Players who want only the puzzles may find the rewards and shops get in the way.
