NumBizzz
Reinventing grid puzzles with deductive subtraction logic
NumBizzz is the ultimate test of deductive subtraction. Solve uniquely generated matrices from 3x3 Sprints to 9x9 Marathons. Why Logic Masters love it: 📉 Matrix Logic: Master MRV Insight and Hidden Sum techniques. 🏟️ The Arena: Compete in Daily, Weekly, and Monthly global challenges. 🛡️ Privacy First: Automatic pseudonyms for the Global Top 50. 📊 Official Archives: Export pro Daily Snapshot PDFs of your wins. Find your flow state and conquer the grid! 🧘♂️🔢
I built this game because I felt most grid puzzles were becoming too mechanical. I wanted to create something that rewarded logical flow and mental endurance, rather than just simple number placement.
NumBizzz is built on a custom Constraint-Satisfaction engine that focuses on deductive subtraction. Whether you’re tackling a quick 3×3 Speedrun or pushing your synapses to the limit with a 9×9 Cosmic Arena match, the goal is to find those perfect “Aha!” moments when the grid finally locks in.
A few things I’m especially proud of: • Privacy-First Arena: Compete globally using unique math pseudonyms. • Daily Archives: Export professional-grade PDFs of rankings and puzzle stats. • Intelligent Logic Coach: Explains deduction steps to help master the matrix.
LAUNCH GIVEAWAY 1. Solve any 5×5 grid today. 2. Post a screenshot of your Victory Screen on X tagging @NumBizzz. 3. I’ll DM you a Google Play promo code.
