Letterex — Word Duel

A word duel on one phone — or take on The Locksmith. Free to play, no ads, no accounts, nothing tracked. One $1.99 unlock opens everything, forever.

Letterex turns spelling into a duel.

Start from a 3-letter word. Take turns reshaping it — GROW it by adding a letter to either end, or SPIN a dial to change one letter in place. Every result must be a real word. No repeats. Corner your rival and the chain seals in your favor — first to 100 points takes the match.

DUEL ON ONE PHONE Pass-and-play battles with family and friends. No second device, no accounts, no setup — hand the phone over and outword them.

FACE THE LOCKSMITH A cunning AI opponent with a personality. Beat him at Apprentice for free — Journeyman and Mastermind await in Letterex Complete.

THE DAILY DUEL One shared duel a day, everywhere in the world. Same word, same spins, the Locksmith at the day's difficulty. No hints, one try — first to 100 wins. Share your spoiler-free result card and settle who's the real wordsmith.

ZEN MODE No opponent, no clock — just you and the cylinder. Keep one unbroken chain alive for as long as the dictionary allows, with unlimited hints and an auto-spin assist.

NOTHING IS COLLECTED No ads. No accounts. No analytics. No tracking. Works completely offline. Your words never leave your device — that's a design decision, not a settings toggle.

FREE TO PLAY — ONE UNLOCK FOR EVERYTHING Letterex Complete ($1.99, one time): all Locksmith difficulties, 3 hints every duel, your full lifetime ledger, and Daily Duel do-overs — replay any past day from the Archive. No subscriptions. No energy meters. Buy once, own it forever.
