A daily literary puzzle
For people who love sentences.
Prose Play's Unscramble is built on fifty years of research showing that one specific kind of practice — reassembling the sentences of great writers — produces writing gains no classroom has ever matched.
In 1973, researcher Frank O'Hare gave seventh graders one semester of exactly this kind of practice. They finished the semester writing like twelfth graders.
Five grade levels of writing proficiency.
One semester.
That's not a fluke. A landmark Carnegie Corporation review of 176 empirical studies ranked sentence combining among the most effective writing interventions ever documented — for students from fourth grade through college.
The gains go deeper than mechanics. Students didn't just write better sentences. They became better storytellers and stronger revisers. And the research found one more thing: gains eroded without continued practice. Which is exactly why we built a daily game.
When learning feels like play — when the challenge is real, the stakes are low, and you can feel yourself getting better — people show up every day.
We applied that principle to the thing that matters most: the sentence.
Difficulty isn't about word count. It's about structural complexity — the same skill a writer develops over a lifetime.
A short base clause. One sensory modifier. The world seen clearly and plainly.
A central action followed by a balanced stack of descriptive phrases. Structure you can feel.
Nested modifiers — phrases that describe other phrases. A layered, psychological flow.
A massive cumulative chain. Meaning that compounds with each fragment. Demanding, and worth it.
We made decisions early. They are not negotiable.
Readers, writers, lifelong learners. Play it before it goes public and tell us honestly what you think.
