Focused skill training

Each round removes one preposition so you can learn usage patterns quickly and reinforce them through repetition.

Competitive scoring: Points combine accuracy, response speed, and streak multipliers. Save runs to a local leaderboard and chase personal records.
Private by default: No accounts or uploads. The game runs in your browser and keeps progress on this device.

Practice strategy

Start with the Basic scope until your accuracy stays above 85%.
Switch to All and use grade filters to progress from Easy to Native.
Use Marathon sessions to build endurance and reduce hesitation.
Use Super Difficult mode for native-level precision and long, high-volume sessions.
Use Endless mode for continuous practice, then finish when you want to save the run.
Review missed answers after each run and replay immediately to reinforce the correction.

Frequently asked questions

Does this game send answers or scores to a server?

No. Gameplay, scores, records, and leaderboard data stay in your browser's local storage.

How many examples are included?

The tool builds a large local corpus from dozens of prepositions and generates thousands of sentence examples with varied contexts.

Can I practice only basic or advanced prepositions?

Yes. Switch between Basic, Advanced, and All, then filter exercises by difficulty from Easy to Native.

Is there a very difficult mode?

Yes. Super Difficult focuses on native-level items and runs a 1,000-question gauntlet with nuanced distractors and precise collocations.

Can I play without an end?

Yes. Endless mode keeps generating exercises until you finish the run manually.

Which prepositions do advanced learners still confuse most?

Common contrast sets include in/on/at, to/for/of/with, since/for/during/from, between/among, because of/due to/despite, before/by/until/after, into/in/to/onto, across/through/along/past, and besides/except/without.

Can I import external dictionary-style examples?

Yes. Add a local JSON pack at /data/prepositions/external-examples.json or build one from CSV with the included script. Only use examples you are licensed to redistribute.

Is this similar to Duolingo?

It uses a Duolingo-style loop: fill-in-the-blank sentences, instant feedback, streak-based points, and repeatable sessions.
