Train Your Brain With Mimi
Mimi posts an abstract-reasoning puzzle every day for people who like to keep their mind sharp. The puzzles are built on Raven's Progressive Matrices, one of the most validated tests of fluid intelligence in psychology. Below is a playable version: a fresh puzzle every time you load the page.
How to play. Each tile holds a ring of coloured dots. Across every row and down every column, the colour and the number of dots each follow a steady rule. Work out both rules, then choose the tile (A to F) that belongs in the empty square. You have 30 seconds.
This is one of the tools I build with Claude Code and free AI tools, then share so other people can build their own. Mimi runs the daily version on Instagram.
