Néro & Sci ∫ Integral Edition

Néro & Sci ∫ Integral Edition follows Néro, a young Synapsian living on the streets of Curiosita, the capital of Heméide. He takes refuge in the library of Psyga, whom he regards as a father figure. While cleaning its basement, Néro drops a jar containing Sci and knocks over a book that unleashes the Chaos theories, sending them into Heméide’s caves. They must find a way out.

Explore Heméide

Heméide is a world of colorful shapes, numbers and mathematical logic. You enter the White Dimension to reveal the shapes, numbers and vectors that make up the world, then observe and experiment to work out the logic behind its puzzles. You can try different approaches and form your own hypotheses; no advanced mathematical knowledge is required. An integrated hint system and a gradual learning curve let you solve puzzles at your own pace. The game’s mechanics have been endorsed by the Institute for Research on Mathematics Education (IREM Lyon).

Solve the puzzles

The game contains 36 levels across four worlds and offers over 20 hours of content. You can replay it to unlock more skill points and improve your understanding of the puzzles. You can play solo or with a friend in local co-op.
