Alfie Puzzles

Bite-size puzzle play for curious kids.

What it is

Alfie Puzzles is built around a simple idea: kids' attention is a precious resource and most puzzle apps spend it badly. Long tutorials, escalating difficulty curves, dark patterns to keep them playing - all of it at odds with what the half-hour after school actually needs. Puzzles aims for the opposite: a varied set of small, finishable challenges that fit a real child's evening.

Why we built it

Sibling app to Alfie Colouring. Once kids ran out of patience for drawing, we wanted somewhere else for them to land that wasn't a video. Puzzles - the kind you can finish in five minutes and feel a little proud of - turned out to be the right shape.

What makes it

  • A range of puzzle types so the same brain doesn't get the same workout twice
  • Sessions that finish - no infinite levels designed to keep kids glued
  • Progress feedback that's encouraging without being patronising
  • No ads, no leaderboards, no social pressure
  • Plays nicely alongside Alfie Colouring for variety in a single sitting

About

A small team, building things we'd want to use ourselves.

Sentium is a small, focused technology studio building consumer products for everyday life. We design and ship our own apps end-to-end - product, engineering, content - with a bias toward privacy-first design and experiences families and individuals can trust.

We work in tight iterations, ship to real people, and learn from what they tell us. Less ceremony, more shipping. Most of what we make is for the people we know - kids, parents, friends - and that keeps the bar honest.
