As answered by people managing Knowt and Knowess.
Knowess's answer:
Knowess started as a personal project to explore the design space of constraint-based number puzzles. The classic Mastermind format felt underrepresented in modern web games — most implementations are visually dated or buried in ads. The goal was to build a clean, fast, and genuinely replayable version with more player control over the rules.
Knowess's answer:
Next.js (App Router), TypeScript, Tailwind CSS, React, deployed on Vercel.
Knowess's answer:
Knowess is a free-to-play game with no paying customers. It serves individual players directly — no B2B customers or enterprise accounts.
Knowess's answer:
Knowess offers two distinct feedback modes — Any Match and Exact Match — that go beyond the standard Bulls & Cows formula. Each mode requires a fundamentally different deduction strategy, and players can also adjust the number length (3–10 digits) and toggle repeated digits. The Daily Challenge adds a fresh puzzle every day with structured hint clues unique to each session.
Knowess's answer:
Most number deduction games lock you into one feedback style. Knowess lets you choose your mode, set your difficulty, and jump straight into play — no account, no download, no ads cluttering the interface. It's designed around pure logical deduction with a clean, distraction-free UI.
Knowess's answer:
Logic puzzle enthusiasts, casual brain-training players, and anyone who enjoys deduction-based games like Wordle, Mastermind, or Sudoku. The adjustable difficulty makes it accessible to beginners while the harder configurations (10 digits, repeats enabled) appeal to experienced puzzle solvers.
