Hi everyone! I’m the maker of NumBizzz. πŸš€

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 3Γ—3 Speedrun or pushing your synapses to the limit with a 9Γ—9 Cosmic Arena match, the goal is to find those perfect β€œAha!” moments when the grid finally locks in.

A few things I’m especially proud of:
β€’ Privacy-First Arena: Compete globally using unique math pseudonyms.
β€’ Daily Archives: Export professional-grade PDFs of rankings and puzzle stats.
β€’ Intelligent Logic Coach: Explains deduction steps to help master the matrix.
