WordAcuity

For players who have outgrown the box

A Boggle alternative that coaches you to get better.

If you love the letter grid but want more than a score that vanishes when the sand runs out, WordAcuity is built for you. Same kind of board. A coach that helps you improve.

What stays the same

Everything that makes a word grid worth playing. You will feel at home in the first ten seconds.

  • A grid of letters, 4×4 to start, with a timer.
  • Trace connected tiles, diagonals included, each tile once per word.
  • Three letters minimum; longer words score more.
  • A real dictionary: based on the ENABLE list, the standard for serious word-game players.
  • Play alone, or against people you know.
  • No account, no sign-up, nothing to join.

What changes when the clock stops

The box game ends with a tally. In WordAcuity, that is where the coaching starts.

The whole board
When time is up you see every word that was there: what you found, what you nearly found, where the long ones hid. Post-game analytics cover words per minute, coverage by word length, near-misses, and a heatmap of the board.
Practice from your misses
Near-misses become a practice set on the spot. Word families you keep skipping get their own drills. Every word carries its definition, one tap away.
A coach
A ten-lesson course, from how scoring really works to hunting long words, and fourteen drills that each target one skill: diagonals, plurals, affixes, power tiles. Short, seeded, and scored, so you can tell whether the drill is working.
Proof you are improving
Acuity is a persistent 0–100 skill rating, updated after every ranked round and normalised for how hard the board was. Not a high score. A number that describes how well you read a grid right now, with a history that shows the coaching paying off.
One shared board a day
A new Daily drops at 9pm Eastern, the same for every player. One timed run, then standings.
Friends, on any schedule
Open a live room, or send a board as a challenge link and let them take their turn when they like. One link opens the game on their iPhone or iPad.
Bigger boards
4×4 is free. 5×5 and 6×6 come with Pro, along with the full Coach library and all-time Lab history.
WordAcuity's post-game review: found words, a words-per-minute chart, coverage by word length, and near-misses.
The screen the box game never had. Every word on the board, grouped by what you found, what you nearly found, and what you walked past. Tap any of them for the definition.

Who it is for

People who play word grids and want to get better at them. Puzzle players who want a Daily they can compare with friends. Anyone who has finished a round, seen the word list, and thought I should have had that.

It is not a party game with timers that shout, and it does not pester you with streak warnings. It respects your attention and coaches you to get better.

Common questions

Is WordAcuity the same game as Boggle?

No. WordAcuity is an independent word-grid game. It shares the familiar idea of tracing connected letters on a grid against a clock, but it is built around coaching you to get better. Boggle is a trademark of Hasbro, Inc., which is not affiliated with WordAcuity in any way.

Can I play for free?

Yes. The 4×4 game, the Acuity rating, the headline analytics, the official Daily, and the first Coach lessons are free on iPhone and iPad. Pro adds 5×5 and 6×6 boards, the full Coach library, all-time Lab history, and unlimited Daily practice.

Do I need an account?

No. Signing in with Apple or Google is optional and only syncs your history across devices.

Which dictionary does it use?

The ENABLE word list, trimmed to three to sixteen letters, with definitions available in the app.
