Everything shipped, straight from the changelog.

There is a new activity type: the advent calendar. It is a wall of numbered doors, one opening each day, with one thing behind every door: a message, a picture, a video, a sound, one of your Puzzel activities, a task or a link. Players open today's door, and a door they missed stays openable.

• Pick the days in one tap. Advent is 24 doors from 1 December, To Christmas 25, and 12 days starts on 13 December. Countdown takes any number of doors from 1 to 31, from any date, so it works for the summer holiday as well as for Christmas.
• Choose when doors open. Under When doors open: On their own day, On dates you pick door by door, or Any time, in any order. A door opens at midnight in your time zone, and until then what is behind it stays on our server, so nobody can peek.
• Make players earn a door. A door can carry a gift tag with A question or A code, and the right answer opens it. With a paid plan, Finish an activity opens a door when players finish one of your other activities.
• Tasks away from the screen. A task door holds something to do, like making a paper snowflake, with a tick for when it is done. Players don't have to tick it to finish the calendar.
• Five scenes. The Winter night is free, with fairy lights that light up door by door and Falling snow to switch on or off. Your colours, Pinboard, Festival of lights and Party come with a paid plan, and the pinboard and the party suit any time of year.
• Fill the doors with AI. Fill doors with AI writes a title and a message or task for every empty door, and a question on some, from a topic or your own prompt, for one AI credit. Doors you already wrote stay as they are. PuzzleGPT makes advent calendars too.

There is a new activity type: Guess who. Two players each hold a secret card from the same set, take turns asking yes/no questions, turn down the cards the answer rules out, and the first to name the other's card wins. Playing alone, the computer holds the secret card, and the result is saved.

• The cards are the lesson. Make animals, countries or planets, and the questions players can ask about them, like "Is it a carnivore?". Players answer about their own card, and a wrong answer is not accepted.
• Four ways to ask, under How do players ask?: Your questions, Yours and their own, Their own questions, or Out loud for players at the same table, where the game just keeps the board. The last two need two players.
• Write it with AI. Give a topic and Write with AI picks the cards and questions and answers every one, for one AI credit. A drawn picture on every card is one credit a picture; your own pictures and emoji are free. PuzzleGPT makes one too.
• Free to play together, with a rematch at the end. Switch on Fact sheets on the cards to give each card a few lines players can read.

A course can now end with a certificate and reward students with badges along the way. Both are in the course settings, under Certificate and Badges, and come with Puzzel LMS on the School, Academy and Trainer plans.

• A certificate for finishing well. Switch on Certificate at the end and set the Minimum average (70% to start). A student who plays every activity and reaches it gets a certificate with their name to print. A card at the foot of the course shows how far they are, and their best result counts.
• Badges you design. Pick a preset picture in the course colours or upload your own, and choose what earns it: an activity (optionally above a score), a page, the whole course, or by hand. Earned stays earned, even if you change the rule later.
• Work outside Puzzel counts too. The new Task block stands for work done elsewhere and can earn a badge. So can a video marked as watched.
• Badges instead of grades. Choose No grades and students see their badges, never a percentage. A course without grades has no certificate; a badge for completing the course does that job.
• A badge report to print, for one student or the whole class. Students find theirs under My badges.

There is a new activity type: the A to Z quiz. Every letter has a clue, the answer starts with that letter, and players go round the ring against the clock: answer a letter, or pass it and come back to it on the next lap.

• Pick your letters in one tap. Start from Whole alphabet, Without the hard letters, A short round (10) or Letters of a word, where SPRING becomes a ring of S, P, R, I, N and G. Or tap the letters you want. A new quiz starts with a short round of ten.
• Sixteen alphabets. Next to A–Z there are Spanish with Ñ, the Nordic, Icelandic, Turkish, Polish, Czech, Slovak and Slovene alphabets, Greek, Russian, Ukrainian, Arabic and Hebrew. Any other letter can be added by hand.
• Hard letters are Contains letters. Few words start with X or Z, so a letter can be switched to Contains: the answer only has to have the letter somewhere, like a fox for X.
• Other spellings count too. Under Also accept you add the spellings that count as well. Capitals, accents and punctuation never matter.
• A wrong answer is final. The letter turns red and the ring moves on, as on the show. A passed letter stays open for the next lap, and players pass with the button or Shift + Enter.
• Five minutes on the clock. Change it under Answers & timing → Countdown timer. When time runs out, or a player taps I'm done, the letters still open count as not answered.
• A result per letter. At the end players see what they got right and wrong and what they typed. With Answers & timing → Show the answers to missed letters at the end switched on, they also see the answers to the letters they missed. It is off by default.
• Fill the letters with AI. In the AI assistant, Fill the letters with AI writes a clue and an answer for every empty letter from a topic or your own prompt, for one AI credit. PuzzleGPT makes one too: ask for "an ABC quiz about animals".
• Pictures and sounds as clues and Challenge mode, where players race round the same ring, need a paid plan. Everything else is free.

Type what you want to teach, like "a crossword about the solar system, for 10-year-olds", and PuzzleGPT picks the kind of activity, writes the content and opens it in the builder, where you check it, fine-tune it and share it. You find it in the What do you want to teach today? box on the homepage, in the same box above your activities in the dashboard, and behind the PuzzleGPT button in the bottom-right corner of the site. It never appears on a page your players open.

• Name a kind, or pick from three. Ask for a word search and you get a word search. If you don't name a kind, it suggests three that fit your topic and you pick one. It makes every kind of activity except label the diagram, hidden objects and interactive video, which are built around spots on a picture or a video you choose.
• Change it by asking. "Make it harder", "add five more words", "call it Planets": it changes the activity in place, starting from what it holds now, so edits you made in the builder are kept. Under each change sits Restore the version before this change, at no cost.
• Settings in plain words. "Add a 5-minute timer", "use 48 pieces", "shuffle the questions": the chat lists what changed by the names the builder uses. Who can open it, Record results, Ask players who they are and Challenge mode are never changed by themselves: the chat shows the change with a Confirm button, and nothing happens until you press it.
• A worksheet becomes an activity. Attach a PDF of a few pages, a photo of a page or a Word file with the paperclip, and say what to make of it: "turn this into a quiz". Your own picture becomes a jigsaw or a sliding puzzle. The worksheet itself is never stored. Attaching a file needs a free account.
• Pictures, emoji or drawn. When the topic suits it, the cards of a memory game, matching game, flash cards or guess who get emoji pictures at no extra cost. With a free account it can draw them instead, for one credit per picture on top of the activity's one, and you see the price before anything is drawn. It draws the picture for a jigsaw or sliding puzzle within the activity's one credit, and with a free account it makes a spot the difference (two credits) or a mystery picture. Pictures on quartets cards need a paid plan, as in the builder. Everything it draws goes into your media library.
• One credit for an activity you got. Each activity it makes or changes uses one AI credit, the same credits the builder's AI assistant uses. A request that makes nothing costs nothing: the three suggestions, a question about using Puzzel.org, a request it can't turn into an activity, or an attempt that fails. A change to only the settings or the name is free too.
• Try it without an account. A visitor gets three free tries. Sign up from the same browser and the activities you made come with you. A new free account starts with 3 AI credits, and every paid plan adds credits each month.
• It sees only what it needs. Your request, the earlier requests in the same chat and, for a change, the activity it is changing. Never your players' results or answers, and never your other activities.
• The activity is an ordinary one. It counts toward your plan's activity limit like one you build yourself, and you edit, print and share it in the builder as always.

PuzzleGPT is offered in a limited number of countries to start with. If you don't see it, it isn't available in your region yet.

There is a new activity type: the Mystery picture. You pick a picture, it is cut into jigsaw pieces, and each piece stays closed until a player earns it: by answering a question, by typing a code they found somewhere else, or by finishing another activity. Piece by piece the picture is revealed, until somebody knows what it shows.

• From 4 to 36 pieces. Choose a size under Picture & pieces, then click a piece on the picture to decide what opens it.
• A question on a piece. Multiple choice, true or false, or a typed answer with the other spellings you accept.
• A code to find. Hide a code on a poster, in a book or on the board, and give a clue in the piece. Capitals and spaces don't matter when players type it.
• A free hint. Choose Open from the start for a piece players get without answering anything.
• Guess it early. With How it plays → The reveal → Guess the picture early switched on, players can guess what the picture shows at any moment. A right guess reveals every piece at once, and the fewer pieces they needed, the higher their score. Wrong guesses cost nothing.
• The story behind the picture. Under What players read when the picture is revealed you write what players see at the end. It is locked with the picture, so it gives nothing away before then.
• No guessing your way through. With Answers & timing → Freeze a piece after wrong answers switched on, a wrong answer shuts the piece for 30 seconds, with a countdown on the piece itself. You can change both numbers.
• No peeking. Every piece is locked until a player earns it, so the picture cannot be read out of the page's code.

With a paid plan there is more:

• Open a piece by finishing an activity. Choose Finish an activity on a piece and pick one of your other activities. Players who finish it from the piece get a Back to the mystery picture button, and the piece opens on its own. If that activity shows a completion code or hides a solution, the code is filled in for you, so players who played it some other way can type it in.
• Release pieces on a date. Switch on How it plays → The reveal → Release pieces on a date and give each piece its own moment, like an advent calendar. Until then a piece shows only its date, even to a player who has its code. The date is checked on our server's clock, not on the player's device.

There is a new activity type: the Map quiz. You pick a ready-made map and click the places you want to ask, and your players find them, name them or drag them into place.

• 38 maps, nothing to draw or upload. The world with its continents and oceans, six continents with their countries and capitals, and 31 countries with their provinces, states or regions and their largest cities.
• You choose what is asked. Every region starts switched on. Click a place on the map to switch it off or on, or use All and None for a whole row.
• Seven ways to ask. Find it shows a name and the player clicks the place. Pick the name and Type the name light a place up and ask what it is called. Puzzle lays the places loose beside the map to drag into position, which is the easiest way to play. Name the outline shows one shape on its own.
• Flags and capitals. On the continent maps a country can be asked By flag or By capital. On most country maps a province or state can be asked by its capital too.
• Place names in the language you teach in. Under Place names in you choose one of 23 languages, and every player sees the names that way, whatever language their own page is in.
• Help after a few misses. A wrong click says what was clicked instead. After three misses the right place starts to blink, or its name is shown. You change the number under How it plays → Give the answer away after; 0 never gives it away.
• Players can choose the order. With How it plays → Players choose the order switched on, nothing is asked in turn: players click a place and then name it. It works with Pick the name and Type the name.
• A worksheet on paper. Print worksheet numbers every place you ask on the map, with a list to fill in. The answer key is the same sheet filled in.

With a paid plan there is more:

• Places of your own. A town, a river or a region the map does not have: Add a place puts a pin on the map and you type its name there.
• Crop to the part you teach. Zoom in on a region and choose Crop to this view; that part becomes the whole map for your players.
• Use it as a test. With Answers & timing → No automatic answer checking switched on, every place gets one answer and nothing says whether it was right. The answers are written on the map as the player gave them.
• See what was mixed up. With Results & tracking → Record results on, the results show for every place how often it was missed and what it was taken for.
• A race, or a team map. Under Multiplayer, Challenge mode lets players race to finish the same map, and Play in teams gives each team one map to fill together.
• A diploma. With On completion → A diploma for a finished map, a player who finds every place gets a diploma with their name, the map and the date, ready to print.
