Alfie Puzzles

Puzzles that grow with your kid.

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
