Zed: A to Z is a sliding puzzle for iPhone built on one rule: two matching letters merge into the next letter of the alphabet. Swipe and the whole board slides; A and A become B, B and B become C, and the climb runs all the way to Z. An Up Next row shows what lands on your next move, so every swipe is a small piece of planning.
Eight modes range from a five-minute race on a cramped 3 × 3 board to a scoreless Zen mode and an Endless climb past Z. A daily challenge gives every player in the world the same board. Free, with one purchase to remove ads.

The eight modes in one line each
- Easy — the classic climb, with tighter letters and more undos.
- Medium — the climb as intended, no handicap.
- Hard — scarcer matches and hidden previews.
- Quick — a five-minute race for score on a cramped 3 × 3 board.
- Long — a marathon climb across a roomy 5 × 5.
- Zen — no score, no game over. Just merging.
- Endless — no finish line; climb past Z to Z², Z³ and beyond.
- Daily — one shared challenge a day, identical worldwide.
New modes unlock as the player progresses.

Privacy, briefly
Games, scores and stats stay on the player's device and in their own private iCloud database, which 4B Studio cannot read. There is no account and no sign-up. The free version shows third-party ads that collect usage data for advertising, not linked to the player's identity; the one-time Remove Ads purchase stops that. Full detail in the Privacy Policy.

You may use the text, screenshots and icon on this page in reviews, previews, round-ups, videos and streams of Zed: A to Z, without asking first. Please don't alter the app icon or present the game as anything other than a 4B Studio release.
