About

LastLetter

Features
Read full description

Say a word, follow the last letter, and keep the chain alive. LastLetter is a quick word-chain game for family game nights or a solo challenge. Choose a category, say or type a word that begins with the previous word's last letter, and beat the clock. Play together on one device, challenge an AI opponent, or start an online match. In Solo Chain and Blitz, chase your best score; the Daily Gauntlet gives everyone the same challenge each day. Supported categories also have ranked leaderboards. Build and share your own categories, or earn new themed packs through play. Discover Cities, Foods, Movies, Football Players and Greek Islands alongside familiar favourites. Try Japanese kana Shiritori, where a word ending in ん knocks you out. Put the game on a second screen for a dedicated TV scoreboard while players keep their controls on the phone. Voice input uses on-device recognition when available for the selected language and device; text input is always available. Free to play, with no ads or in-app purchases. No LastLetter account required.

Verdict

The call

The clearest difference is price: LastLetter at Free against ArcEmu's $1.99. LastLetter also leads on update cadence (every 5 days vs every 2 weeks). ArcEmu's advantage is device support (5 vs 2) and iOS requirement (15.5 vs 26.0). On ads and in-app purchases there is nothing between them.
