Go beyond reading with customized solutions designed to expand your vocabulary and deepen your reading comprehension. Our interactive activities are engineered to accelerate your path to fluency.
Reading builds vocabulary naturally; direct vocabulary training measures and reinforces exactly what you know. Our levelled Vocabulary Challenges test your understanding of over 3600 words as they are used in real contexts, and are updated regularly. They are organized in six levels aligned with the CEFR scale, the same levels used throughout this page: passing a level confirms the vocabulary you have mastered at that level, while a level you cannot yet pass points to the vocabulary to target through extensive reading, intensive reading and further practice — including the Learning Games below — before you try again.

To move up a CEFR level, learners need to expand the English vocabulary they know, through two complementary paths: reading extensively for pleasure, and direct vocabulary training like the Vocabulary Challenges above. These six story-driven games put that training into a fun, game-based format: climb six CEFR mountains to build your vocabulary, enter six halls to master English grammar, solve reading mysteries as a detective, travel by train across the English-speaking world, take the Sentence Forge grammar challenge, and travel through history as a Time Agent. Each game is organized in the same six CEFR levels, from A1 to C2: the levels a learner passes show which levels of English they have mastered, and the levels they cannot yet pass show exactly where to focus next, through the matching extensive reading and intensive reading books and stories.
