Kids Word Games

2025–2026Case study
Kids Word Games hub showing the daily game collection

Build a broad literacy game collection that feels playful to a child while remaining predictable, correct and maintainable behind the scenes.

My role

Product designer, developer, content-system designer and test author.

  1. 01Twenty-two engineered game systems, with eighteen currently surfaced in the daily hub
  2. 02Child-friendly interaction without patronising the player
  3. 03Large editorial datasets where small errors become visible quickly
  4. 04Deterministic behaviour needed for reliable testing
  • Twenty-two connected word, numeracy, music, coding and reasoning game systems
  • Editorial tools for preparing and checking game content
  • Deterministic validation for words, rounds and outcomes
  • Shared interaction patterns and accessible feedback
  • A test suite covering core rules and edge cases
Key decisionsHow the work moved
01

Separate play from content

Editors can improve the language material without rewriting each game, while game logic remains testable.

02

Remove accidental difficulty

The challenge should come from language and decisions—not unclear controls or inconsistent rules.

03

Test the boring edges

Deterministic fixtures make it possible to verify thousands of cases that a person should not have to check by hand.

01Child-facing simplicity usually requires adult-level rigour behind it.

02A content tool is part of the product, even when the player never sees it.

03Tests create room to experiment because they make unintended change visible.
