Decimals & Fractions: 8 new lessons, 20 new challenges

All newsPlayers around this dateRead on Steam

We've been hard at work on the next big content drop for SLF: 8 brand-new math lessons and 20 new challenges, all built around decimals and fractions — coming late May.

Learners explore why a number breaks apart and how to tame it — through story, characters and hands-on challenges, never rote drilling.

New here? SLF (Sur le Fil) is a narrative educational game for ages 8–15. Maths, electricity, writing, science, geometry and mechanics — taught through an adventure across a living campus, with Prof'Fil and his cast, not worksheets.

It doesn't follow the school curriculum: it follows the logic that makes concepts click.

📅 Landing in SLF late this month.

➕ Wishlist or follow SLF so you don't miss it — a wishlist genuinely helps a solo dev. Thank you.
