## What is Rulo?

Three boards of shapes. One secret rule. Can you find it?

Rulo is a daily deduction puzzle. Every board you see follows a hidden rule — maybe "more red than blue", maybe "exactly one shape touches the edge", maybe something trickier. Your job is to work out what it is.

BUILD AN EXPERIMENT
Place circles, squares, triangles and diamonds on a 4×4 board and check it. The game stamps it: fits or doesn't fit. Every check is saved, so you can compare, copy and tweak your boards until the pattern clicks.

SAY "I KNOW!"
When you're sure, prove it: sort five new boards into "fits" and "doesn't fit". Get one wrong and Rulo shows you exactly which board broke your theory.

A NEW RULE EVERY DAY
The rule of the day is the same for everyone. Keep your streak going, compare your score on the Game Center leaderboard and share a spoiler-free result card with friends.

LEARN AS YOU PLAY
Twenty short lessons teach every trick: colors, counts, edges, corners, symmetry and combined rules.

MADE FOR EVERYONE
• Patterns on shapes, so color is never the only clue
• Full VoiceOver support and Dynamic Type
• Light and dark themes
• Home Screen widget and a Live Activity while you solve
• No account, no ads, works offline
