Role on Puzzle Workout

Making the puzzle work all the way through.

Brian’s role covers the technical path from a game idea to a reliable browser experience. That includes the visible puzzle, but also the systems underneath it: deterministic generation, validity checks, scoring contracts, local storage and responsive interaction.

01

Product architecture

Structuring a static Astro site where five independent games can also run inside one resumable Daily Brain Workout.

02

Generation and validation

Turning seeds into reproducible questions, then checking the properties that make every generated puzzle fair.

03

Scoring and progress

Normalising different raw game results while weighting accuracy first and suppressing rewards for chance-level speed.

04

Technical editorial review

Checking that explanations match the implemented rules, generators, difficulty settings and score calculations.

Work on this site

Game systems you can use now.

These are concrete parts of the current Puzzle Workout site. Karan Hamilton also contributes puzzle ideas, testing, wording and player-experience judgement across the project.

Engineering fair puzzles

Correct output is a product feature.

A generated puzzle should not reach the player merely because it looks plausible. Each game needs explicit invariants that can be tested in code.

  • Grid Recalluses unique positions and difficulty-aware patterns.
  • Target Huntprevents any distractor from becoming an accidental exact match.
  • Pattern Sequenceuses named rule families and four unique options.
  • Quick Mathskeeps answers exact, including whole-number division.
  • Shape Rotationrequires one rotation match and rejects ambiguous reflections.

Authorship and review

What a Brian Hamilton byline means here.

A visible author name should identify real responsibility rather than decorate a search page.

Written or substantially editedThe page’s explanations and examples received direct editorial work.

Technically reviewedClaims about the generator, controls, difficulty and scoring were checked against the implementation.

Kept within scopeRecreational puzzle results are not presented as IQ, education, health or diagnostic measures.

Background beyond this site

Long-term web development, applied to puzzles.

Brian has an internet engineering degree and 30 years of development experience. His puzzle work focuses on web-based games, playable boards, generators, solvers and tools that explain or enforce logic reliably.

He leads Hamilton Digital Media Limited and is a co-founder of Sudoku Online Puzzles. Across the wider network, his role often sits between engineering and editorial judgement: the page must behave properly, but the puzzle must also be clear and satisfying to solve.

Built collaboratively

Engineering needs a player’s eye.

Karan Hamilton contributes puzzle design, testing, wording, instructions and first-time-player judgement. Puzzle Workout is stronger when technical invariants and human clarity are checked together.
