Tilewright: seven tiles, one opponent, and a board nobody else uses

A free letter-tile word game you play in a browser tab against an AI opponent on a 13×13 pinwheel board built from scratch — three difficulty tiers, a shared daily rack, and no account at any point.

What it is, and what it deliberately is not

Tilewright is a letter-tile word game you play in a browser tab. You hold seven tiles, you build words across a shared grid, and one AI opponent answers you turn for turn. It is free, there is no account, and there is nothing to install: the first screen is already a dealt game, not a menu.

A match is a complete game rather than an endless score chase. You play until the bag is empty and one side uses their last tile, or until four consecutive scoreless turns end it. A match has a shape: an opening where the board is wide, a middle where you fight over specific squares, and an endgame the racks decide.

What is not in it matters too. No human multiplayer, no chat, no leaderboard, no in-play hint button, no account keeping score on you. The game is supported by advertising, which is why it costs nothing. And it is not a branded board wearing a different name: the grid, the bonus layout, the tile values and the word list are its own.

The board is the unusual part

The grid is 13 × 13 — 169 squares — and 45 of them are bonus squares: 8 triple-word, 9 double-word, 4 triple-letter and 24 double-letter. The layout turns rather than mirrors. Rotate it a quarter turn and it is identical; hold it to a mirror and it is not. Almost every board in this genre is mirror-symmetric, which puts premium squares in matched pairs you can plan against from both sides.

The consequences are specific. The eight triple-word squares sit on the four corners and the four edge midpoints, so the edges are where the enormous turns live, and leaving a letter within reach of one is how a comfortable lead disappears. Four of the nine double-word squares form a diamond one step out from the centre, so a three-letter word straddling two of them is worth four times its face value. The centre square is itself a double-word, so the opening word, which must cover it, is doubled by definition.

The tile set is just as specific. The bag holds 96 tiles: 93 letters and 3 blanks. Values run along a ladder of 1, 2, 3, 4, 5, 8 and 11 and nothing else — Q and Z at 11, J and X at 8, K at 5, V at 4, F, H, W and Y at 3. Seven tiles in one turn pay a flat 45 on top, and three blanks in the whole bag, shared between both players, makes a blank genuinely scarce.

Three opponents, and why none of them cheats

The opponent comes in three tiers — Apprentice, Journeyman and Wright — and they are not three programs with different rules. They are one move generator with three ways of choosing from its ranked list of legal plays. All three see the same board and the same dictionary you do, and none of them can see your rack.

What separates them is judgement. Apprentice picks from the middle of its list, roughly the 55th to 85th percentile of what it found, and does not think about the rack it will be left holding: it plays a strong word at the wrong moment. Journeyman weights its choice toward the top fifth and does care about keeping a workable mix of vowels and consonants. Wright takes the move with the best combined score and rack value, tracks which letters are still in the bag, closes the board when it is ahead, opens it when it is behind, and plays the endgame out exactly.

That structure is the point: losing to Wright should feel like being outplayed rather than out-cheated. One win unlocks the next tier — no timer, no grind.

The Daily Rack, and a number that tells the truth

Once a day, every player gets the same seven tiles on an empty board. The rack is derived from the UTC date rather than picked by a server, so nobody is dealt an easier hand. You get a single submission: your best opening word.

Then the game does something more interesting than scoring you against strangers. It enumerates every legal opening word that rack could have played — usually a few hundred — and reports where yours landed: "your 34 beats 91% of every word playable from today's rack." That counts words, not people. With no server and no other player's score to compare against, "you beat 91% of players" would be a fabricated social signal.

What it reveals after you submit is worth more than the percentile: the best word the rack could have played, and the best word at each length it allows. That ladder is the useful part, because the longest word is not automatically the biggest. The centre star doubles whatever you place on it, so a short word on a letter bonus regularly out-scores a longer word played flat.

Play on consecutive days and a streak builds, kept in your own browser per device, while an archive of about a month of past racks stays readable.

Playing it on a phone, and how a turn actually feels

The game is built thumb-first. Tap a rack tile to lift it, tap a square to set it down, tap a tile you placed this turn to take it back. Squares that cannot legally accept your tile visibly refuse it, so you are never guessing why a placement will not take. The score preview updates live, and the primary button becomes "PLAY WORD" only once a legal word is on the board — with nothing placed it reads PASS instead, because a greyed-out button you cannot act on is a dead end.

Two small controls do most of the ergonomic work. Shuffle rearranges your rack, worth doing more often than feels necessary: a rack you have stared at for two minutes is a rack you have stopped seeing. Recall pulls every tile you have laid this turn back, so a plan that stops working costs you nothing but the thought. A zoom toggle fits the whole grid onto a 360-pixel-wide screen, and a mini-map shows where you are looking.

How a match ends, and what the results sheet tells you

A game finishes one of two ways. If the bag is empty and you play your last tile, you go out: you gain the value of every tile still on your opponent's rack and they lose it, so going out first is often worth more than the word you were saving. If neither side can score for four consecutive turns, each player instead loses the value of their own leftover tiles. You can exchange tiles rather than play, but only while the bag holds a full rack of seven.

The results sheet is where the game earns its place. It shows both scores, your best word rendered as actual tiles, and the panel that is genuinely rare in a free browser game: the three turns where you left the most on the board. Each redraws the board exactly as it stood when you played, shows your word cold, then fires the word you missed through the same animation a real placement gets. Only gaps of eight points or more count, and it says plainly that it covers the turns it checked.

Finally there is a share card: a 1200 × 630 image with your score, the tier you faced and one word. The whole brag, and no caption needed.

Questions people ask

Is Tilewright free, and do I need an account?
Free, and no account. The game is supported by advertising, which is why it costs nothing, and there is nothing to sign up for or install. Your streak, tier progress and best scores are kept in your own browser rather than on a server.
Does Tilewright work on a phone?
Yes — it is built mobile-first, with tap-to-place tiles rather than dragging, a zoom view that fits the whole 13 × 13 board on a 360-pixel-wide screen, and a mini-map for orientation. The page loads once over the network; after that the dictionary and the AI opponent both run inside your browser.
What word list does Tilewright use, and could a word be missing?
It ships ENABLE, a public-domain English word list, compressed and downloaded once. About 160,000 entries ship, after slurs and profanities were stripped out at build time — so the opponent cannot play one either. Because it is a fixed list rather than a live service, an unusual word can genuinely be rejected.
Does the AI opponent see my tiles or cheat?
No. All three tiers see the same board and the same dictionary you do, and none of them can see your rack. They differ only in how they choose among the legal moves they can find — Apprentice picks from the middle of its list, Journeyman weighs score against the rack it keeps, and Wright also counts the tiles left in the bag and plays the endgame exactly.
Is the Daily Rack percentile a comparison with other players?
No — it counts words, not people. The game enumerates every legal opening word the day's rack allows and reports the share of them your submission beat. That figure is computed in your browser from the board itself, because there is no server and no other player's score to compare with.
Can I play against another person, or get a hint during a game?
Neither is in the game. There is no human multiplayer and no in-play hint button. What you do get is recall, rack shuffle and the ability to take back tiles you have placed this turn, plus a panel after the match showing the three turns where you missed the most points.

Tilewright — a free browser word game against an AI opponent

Tilewright deals you seven letter tiles on a 13×13 board whose bonus squares are arranged in a four-fold pinwheel, and puts one opponent across from you. Tap a tile, tap a square, and the tile lands; tap it again to take it back. When the word is legal the score preview lights up, and playing it fires the bonus squares beneath it one at a time before the machine answers.

It is free, it runs entirely in your browser, and nothing you type leaves your device — the dictionary is searched locally.

How do I play a word game against the computer for free?

Open Tilewright and play — there is no sign-up, no download and no payment at any point. The board is already dealt when the page loads, so your first action is placing a tile rather than picking something from a menu. The site is supported by advertising, which is why the game itself costs nothing.

What makes the Tilewright board different?

The board is 13×13 — 169 squares — and its bonus squares have 90° rotational symmetry rather than mirror symmetry. Turn the board a quarter turn and it looks identical; hold it to a mirror and it does not. The premium squares sit in arms reaching out from the centre instead of in matched pairs, so the board opens along diagonals and the corners stay reachable for longer. The full map and the exact counts are on the board page.

How hard is the AI opponent?

There are three tiers and they differ in what the opponent considers, not in how much it is allowed to cheat — all three see the same board and the same dictionary you do, and none of them sees your rack. Apprentice plays a word it can find and often the wrong one. Journeyman ranks its options by score and by the rack it would be left holding. Wright does that, tracks which tiles remain in the bag, closes the board down when it is ahead, and plays the endgame out exactly. Beating one unlocks the next.

What is the Daily Rack?

The Daily Rack is one shared opening: every player in the world gets the same seven tiles on an empty board, derived from the UTC date, and you get a single submission. When you submit, the game enumerates every legal opening word the rack allows and tells you what share of them your word beat. Past days stay readable in the archive, one page each.

Do I need an account?

No — there is no account, no login and no email field anywhere in Tilewright. Your game in progress, your statistics and your daily streak are stored in your own browser, which also means clearing site data clears them.

Frequently asked questions

Is Tilewright free?
Yes — Tilewright is free to play, supported by advertising. There is no paid tier, nothing to install and no account to create.
Do I need to sign up or download anything?
No. The game runs in the browser you are already using; there is no sign-up, no app store and no download beyond the page itself.
Can I play a word game against a computer opponent?
Yes — every game is against the computer, at one of three tiers: Apprentice, Journeyman and Wright. Beating a tier unlocks the next one.
How strong is the AI?
Apprentice finds a legal word but chooses badly, Journeyman ranks moves by score and by the rack it will be left with, and Wright adds bag tracking, board-closing play and an exact endgame. None of them can see your tiles, and all three use the same dictionary you do.
What dictionary do you use?
ENABLE, the public-domain English word list. We ship the 160,026 entries that fit the board, having removed 206 slurs and profanities at build time — so the opponent cannot play one either.
How big is the board and how many tiles are there?
The board is 13×13, which is 169 squares, and there are 96 tiles in the bag including three blanks. Letter values run 1, 2, 3, 4, 5, 8, 11, and using all seven tiles in one turn pays a bonus of 45.
What is the Daily Rack and how is the percentile calculated?
Everyone worldwide gets the same seven opening tiles each day, chosen from the UTC date, and you get one submission. The percentile is an exact enumeration of every legal opening placement the rack allows, computed in your browser — it tells you that your word beats a given share of every word playable from today’s rack, not that you beat other players, because there is no server and no other players’ data to compare you with.
Does it work on a phone?
Yes — the phone is the primary design. You tap a tile and tap a square; no dragging is required, and the whole board, rack and controls fit a 360px screen without scrolling.
Is the board a copy of another game?
No. The 13×13 grid, the 90° rotational pinwheel arrangement of its bonus squares and the 96-tile distribution behind it are our own design, worked out for this game and documented square by square on the board page.
