20+ space-themed mini-games that make arithmetic, logic, and spatial reasoning fun — from cipher relays to magic squares. Fresh challenges every launch. Blast off into a galaxy of math! NumberNebula turns arithmetic, logic, and spatial reasoning into 20+ hand-crafted, space-themed mini-games for primary-school explorers and up. Every mission is a different kind of puzzle, so practice never feels like a worksheet: • Cosmic Triangles & Magic Squares — balance numbers so every side and line matches. • Arithmancer Crosswords — fill a grid so all the intersecting equations work out. • Komm-Relais — crack a Caesar cipher with a real cipher wheel to decode alien signals. • Codebreaker & Cryptex Lock Breaker — solve interlocking equations to reveal the secret. • Cargo Loader — a push-optimal Sokoban for cosmic logistics. • Asteroid Hunter, Hyperdrive Gates & Gravity Sling — fast, arcade-style number challenges. • 3D Block Counter & Anomaly Scan — rotate, count, and match to train spatial thinking. • KenKen, Number Walls, Signal Triangulation, and many more. Built for young learners: • Adaptive difficulty that quietly focuses on the facts your child finds tricky. • Grades 1–4 progression across number ranges and operations (+, −, ×, ÷). • English and German throughout. • Fully offline. No ads. No accounts. No data collection. No third-party tracking. Whether it's a five-minute warm-up or a longer study session, NumberNebula makes numbers an adventure.
