June 11, 2026 – Oyonnax, France – In arithmetic, 1 + 1 is always equal to 2.
This is precisely what Souris-Lab aims to demonstrate by participating in the Nintendo Multiplayer Sale with Néro & Sci ∫ Integral Edition, its cooperative puzzle game where mathematics becomes a playground for experimentation and collaboration.
From June 11 to June 21, Nintendo Switch players can discover or rediscover the adventure for £8.90 instead of £13.49 thanks to a 33% discount.
Since its release, numerous press reviews and player testimonials have highlighted a particular aspect of the game: its local co-op mode. By allowing two players to solve logic puzzles together, Néro & Sci ∫ Integral Edition creates a shared and collaborative experience between friends or family members, where the world of mathematics can sometimes feel intimidating when faced alone.
Plug in a second controller and share the adventure: the first player controls Néro while the second takes on the role of Sci. Together, the two characters must observe, experiment, and combine their ideas to progress through a world full of puzzles.
In Néro & Sci, 1 + 1 is often worth more than 2. The best solutions usually emerge from discussion, shared thinking, and sometimes even disagreement between players.
Available on the Nintendo eShop, Néro & Sci ∫ Integral Edition is discounted by 33% during the Nintendo Multiplayer Sale, reducing its price from £13.49 to £8.90.
And since 1 + 1 = 2, owners of A Tale of Synapse: The Chaos Theories also benefit from an exceptional 70% loyalty discount. They can purchase Néro & Sci ∫ Integral Edition for only £4.04 instead of £13.49 throughout the promotion.
