About
Every morning, Master Horatio Pell builds a new lock, and he is quite sure you won't open it.
Cogword is a daily word puzzle made of 25 brass letter wheels. Turn the wheels until every row and every column spells a word, and the vault swings open. The catch: some wheels are joined by gears. Turn one and its neighbors turn too, sometimes the same way, sometimes the opposite. One clever move can fix three letters at once.
HOW IT WORKS
• Tap a wheel to pick it, then roll it back or forward with the big buttons.
• A lamp lights when a row or column is set right.
• Light every lamp to open the lock.
• Match Horatio's par for three stars.
A NEW LOCK EVERY DAY
Everyone gets the same lock each day. Locks are gentle early in the week and toughest on Sunday. Keep your streak going and see how far it runs.
MEET THE LOCKMAKER
Horatio teaches you the wheels himself, grumbles when you solve a line, and is secretly pleased when you beat his par.
COLLECT CHARMS
Solve locks at par to earn brass curiosities for your Curio Cabinet: 36 to find.
STUCK?
Ask for a hint, or let Horatio show you the solution step by step. After any solve, watch the lockmaker's own shortest route.

What's New in Cogword
1.1
November 6, 2026
Seasons in the workshop. Autumn leaves drift through Cogword until the end of November, and from 1 December the workshop is dusted with snow and strung with lights. Horatio dresses for the weather too. Prefer the plain workshop? Switch off Seasonal decorations at the end of How to Play. A share card. Share now sends a picture of your opened lock, with its lamps lit, your stars, moves against par, time and streak, and never the words. New sounds for the vault's bolts and door. And if you enjoy Cogword, you'll find "Rate Cogword" at the end of How to Play.
