Use the language, not a lecture.
Games begin with a language behavior: meaning, listening, retrieval, register, response, or production.
Language practice through games
Keep your mind
in motion.
Short, focused games that make language practice worth returning to. Korean comes first, with English guidance here and a separate Japanese-guided version.
Early product prototype • direct task feedback • no proficiency or learning-outcome claim
TODAY / KOREAN 001
PROTOTYPE
Evidence without theater.
Accuracy, latency, assistance, direction, and context stay attached to the task that produced them.
Sophistication, not age.
Foundation through Advanced changes the linguistic demand—not the maturity of the interface, situations, or player.
Playable language prototype
Three rounds. Three kinds of language judgment.
Signal Shift samples meaning, adult functional context, and social nuance. Multiple-choice recognition is diagnostic practice only: it is not productive mastery, scheduled-memory evidence, JLPT/CEFR scoring, or validated proficiency.

Three contextual recognition rounds across meaning, intent, and social nuance.
Choose a lane, then begin.
Press start to begin.
Diagnostic-recognition demo only. First-response latency and assistance describe this task, not memory, fluency, or learning gains. If measurement is allowed, Nakimaru records a session summary but not individual answer choices.
The planned language system
Not a shelf of vocabulary quizzes.
A practice that changes shape.
Nakimaru is being designed around short daily language sessions, varied game mechanics, explicit sophistication bands, and progress views that say exactly what was measured.
01 / DAILY PLAN
A focused session, not an endless feed.
A compact sequence can change mechanic while staying inside one language lane and one coherent practice history.

02 / TASK EVIDENCE
Progress without a fake fluency number.
Planned history keeps direct measures separate so recognition cannot quietly masquerade as production.

04 / WHERE THE GAMES CAN GO
ListeningAct on what you heard, not a transcript.
Rapid retrievalProduce the needed form under time pressure.
RegisterChoose what fits the person, setting, and stakes.
Bidirectional meaningMove between language and intent in both directions.
Sentence productionConstruct a response rather than selecting one.
Language consequencesLet comprehension and expression change a story or game state.
PLANNED MECHANIC DIRECTIONS — NOT CLAIMS OF SHIPPED FEATURES
Evidence discipline
A task result is not a fluency verdict.
Nakimaru can report what happened inside a language task: first-attempt accuracy, response latency, assistance, direction, context/register performance, and whether the task required recognition or production. Broader learning or proficiency claims require evidence the product does not yet possess.
01 First attempts remain distinct from assisted retries.
02 Recognition does not masquerade as productive mastery.
03 Internal bands do not masquerade as JLPT, CEFR, or fluency levels.
04 Learning-outcome claims require evidence before marketing.
Planned access model
One plan. More ways to practice.
A Nakimaru Labs membership is planned with Korean first, English and Japanese guidance, and more languages to follow.
Korean comes firstOne planned membership would include both guidance lanes and future Nakimaru Labs language games as they become available.
