Make a Word Game With AI: Word Lists, Rules and Cost

A word game is quick to describe and unusual in one respect: the mechanics are the easy part and the word list is the real work. Describe the format, the guess rules and the scoring, and Zugo builds a playable browser version in about a minute. A build costs 6 credits, an edit 3.

Everything else in the genre follows from that split. Grids, timers, tile colours and keyboards are ordinary interface work. Deciding which words count as words is a content problem, and it is where a generated word game either feels solid or falls apart on the third round.

Which word formats generate well?

The ones with a rule you can state in a sentence. Most classic formats qualify, and the difficulty is fairly predictable.

The rows marked easy share a shape: one hidden word, a fixed number of attempts, and immediate feedback per guess. The harder rows need generated layouts, and layout generation is where a first build most often produces something valid but ugly.

Crosswords are the genuinely awkward case. Clues are writing, not code, and a grid that interlocks cleanly is a constraint problem. It can be built, but expect several passes rather than one prompt.

Where does the word list actually come from?

From the prompt, unless you say otherwise. Ask for a word game without mentioning the list and you get a small set of words embedded in the game, which is fine for a demo and thin for anything people play twice.

Three options are worth knowing. Embed a list you supply, which gives you complete control over difficulty and tone. Ask for a list of a few hundred common words of the right length, which is fast and good enough for a party game. Or connect a database and store the list there, which is the option that lets you add words later without editing the game.

The choice matters more than it sounds because it decides how the game ages. A game with thirty words is finished after thirty rounds, and players notice repeats faster than anyone expects. If the game is meant to last, plan the list before you tune the colours.

For anything list-heavy, connecting Supabase turns the word set into data you can extend, which is described in an AI app builder with Supabase.

What does the prompt need to say?

Six lines cover a guessing game completely, and the same skeleton adapts to the other formats.

The validation line prevents the most common complaint about generated word games. If any five letters are accepted, players brute force the puzzle and the game stops meaning anything. If invalid guesses cost a try, players get punished for typos.

As always it helps to say what to omit: "no accounts, no statistics screen, no share button yet". Those are good features and they are better added deliberately later. Prompt structure is covered in how to write a good prompt.

How do you validate guesses without a full dictionary?

By deciding what counts, and saying so. There are three workable approaches and they suit different games.

The strictest is one list for both roles: the game picks answers from it and accepts guesses only from it. This is simple and predictable, and its weakness is that a real word outside the list gets rejected, which feels wrong to the player.

The looser version uses two lists: a short list of answers and a longer list of acceptable guesses. That is how most polished guessing games behave, and it is worth asking for explicitly because a generator will not assume it.

The most forgiving is to accept anything of the right length and treat guessing as the player's own problem. It suits fast party games where the fun is speed rather than fairness. Pick one on purpose, because the feel of the game changes completely between them.

How do you make a daily puzzle everyone shares?

Ask for the word to be chosen from the date rather than at random. That is the entire trick: the same calendar day maps to the same entry in the list, so two people playing on the same day see the same puzzle without any server involved.

That approach has a real limitation worth naming. Anyone can read the list in the page source if they want to, so it works for a game among friends and not for a competition with something at stake.

Scores that survive a browser refresh, streaks, and a shared leaderboard need a database. That means a Supabase connection and work layered on top of the game rather than a line in the chat. It is a reasonable next step, not a detail.

The middle option is storing the streak in the player's own browser. It survives refreshes, it does not follow them to another device, and it costs one edit.

How do you make it work on a phone?

Word games live on phones more than any other genre here, so the on-screen keyboard is not an afterthought. Ask for it in the first prompt: a full letter layout under the board, with enter and delete, sized for thumbs.

Two details decide whether it feels right. Keys should show their state, so letters already ruled out are dimmed. And the board should never be covered by the keyboard, which means asking for the layout to fit the screen without scrolling.

Test at the published address on a real phone rather than in a narrow desktop window, since the two behave differently once a virtual keyboard opens and pushes the layout upward.

What does a word game cost to build?

Cheaper than most genres, because there is no physics to tune and no difficulty curve to balance.

A typical route is a build plus three or four edits: validation behaviour, the on-screen keyboard, the reveal screen, and a longer word list. Pro is $25 a month for 200 credits, roughly 33 builds or 66 edits, and Business is $99 a month for 800 credits.

Free grants 5 credits, which is under the cost of a single build, so the starter grant is for exploring rather than finishing. Cloning any of the 25 templates, five of which are games, costs no credits.

What are the honest limits here?

Games are 2D and run in the browser, which is exactly where word games belong, so the format limit costs you nothing.

Language quality is the real boundary. A generated word list in English will be serviceable and occasionally odd, and in a language with rich inflection it needs a supplied list to be respectable. If the game is for a specific audience, provide the words rather than hoping.

Crossword generation, clue writing and difficulty rating are the parts that need several passes rather than one prompt, which is the normal shape of specific logic here. Anything shared between players needs a database. Your code exports to GitHub if you want to continue by hand, and Zugo does not replace a development team on a larger product. A genre with the opposite balance, where mechanics are everything and content is nothing, is a snake game.

What is the fastest useful first version?

One format, one list, one screen. Ask for a five letter guessing game with six tries, colour feedback, an on-screen keyboard and a reveal on loss, and play it ten times.

Ten rounds tell you two things nothing else will: whether the words are fair, and whether invalid guesses are handled the way you want. Fix those before touching anything visual, because a word game with the wrong list is not fixable with colours.

Then publish to an address like your-word-game.zugo.run and send it to a friend, since word games spread by link better than any other genre. Start at zugo.dev.
