Promptle is NightCafe's daily AI art puzzle — think of it as Wordle for image editing. Each day there's one puzzle: you're shown a Start image and a Target image, and your goal is to transform the start image into the target using AI edit prompts. You get 5 steps, and it's completely free to play — today's first attempt, extra tries, and past puzzles.
Promptle is in Alpha. We're still tweaking how it works, and we'll only keep developing it if the community really likes it — so give it a go and let us know what you think!
There's one puzzle per day (it rolls over at UTC midnight). Many days include more than one difficulty level (see below). The page shows a countdown to the next puzzle (for example, “Next Promptle in 5h 12m”). If you ever see “There's no Promptle puzzle today”, just check back tomorrow.
Keep each edit prompt short — there's a 100-character limit per prompt. Promptle's images are generated with a fast prompt-to-edit model (Flux 2 Klein 9B Fast) at 1024×1024px. It's not the most powerful image editor available, so simple, clear prompts work best. Don't spend characters on phrases like “leave everything else the same” — that is handled automatically.
Many days include more than one difficulty. You can switch between Beginner, Intermediate, Advanced, and Expert on the Promptle page. Each level uses the same start image with a different target, and each has its own leaderboard.
Play one level at a time. Finish the attempt you're on before switching to another difficulty.
The results screen can offer a next step:
Your first play of the day on a difficulty counts on that level's ranked leaderboard.
After you've finished a level, you can still:
Those extra plays are free and do not count on the ranked daily leaderboard — they're for practice.
While you're on an extra play, a short note appears under the prompt box: Replays are not eligible for leaderboards. Next to it you can tap Cancel replay (or Go back, if you started another difficulty and haven't submitted a prompt yet) to return to your ranked result without finishing the extra play.
You can replay today's puzzle only while it is still open. After it closes, you can't start another run of a puzzle you've already finished — but you can still play past puzzles you haven't finished yet (see Past puzzles below).
This is different from the replay video on the results screen (a stylised recap you can watch or share). That video is free and does not start a new play.
The Promptle archive lists previous daily puzzles. Open it from the results screen (Browse archive), or go to creator.nightcafe.studio/promptle/archive.
Playing a past puzzle is free and unranked. You get one play per past puzzle. If you leave it unfinished, you can come back and finish it. Once you've finished a past puzzle, you can't replay it.
While you're playing a past puzzle, a short note appears under the prompt box: Past puzzle plays are not eligible for leaderboards.
If a past puzzle has already closed and you never started it (or never finished it), you can still open it. You'll see the start and target images, any attempts you already made (read-only — you can't submit more edits), that day's leaderboards, and a button to play today's Promptle. A note explains that the puzzle ended before you could play or finish it. Secrets (the keyword and secret detail) are shown only if they were unlocked for you.
Each turn, your edited image is compared to the target image and scored out of 100. Reach 90% to win. Your score is made up of six factors:
Every puzzle has a daily leaderboard (and a friends leaderboard if you follow other players). When a day has multiple difficulty levels, each level is ranked separately.
After the day's puzzle closes, you can also learn from other players' winning prompts — see Sharing your prompts below. Yesterday's puzzle card on the Promptle page points you to the leaderboards. If you finished yesterday's puzzle, the keyword and secret detail are revealed there. If you didn't finish it, those secrets stay hidden — you can still check the leaderboards for shared winning prompts.
Sharing your Promptle prompts is optional and off by default. If you opt in, other players can see the edit prompts you used — but only after that day's puzzle closes. Your prompts stay hidden on today's live leaderboard.
This is separate from sharing a results card, and separate from publishing Studio creations. Promptle prompt sharing does not publish your Promptle images to Explore.
Once a puzzle has closed:
Finishing Promptle counts toward your daily activity on NightCafe — when you're done, you can claim your daily streak reward (if you haven't already claimed it that day). See Streaks & Badges for more.
When you finish — win or lose — Promptle creates a shareable results card showing your score, the start and target images, your final image, and a row of color-coded squares for each step (green for a great match, down through yellow and orange to red). Tap Share or Download to post it and challenge your friends. Shared cards and replay videos point to www.promptle.game. This results card is not the same as sharing your actual prompts on the leaderboard, and not the same as starting a new play of the puzzle.
Didn't get there? You can try another difficulty or replay this one (see above), or share your result and come back tomorrow.
