What is Lost Sword?
Lost Sword is a 2D side-scrolling action RPG with heavy AFK mechanics developed by Wemade Connect. The game boasts an "Action x Flirting" isekai storyline where players team up with anime-styled heroines—like Princess Elizabeth and Fairy Queen Morgana—to find the legendary Excalibur. While it features flashy, high-quality skill animations and fully voiced characters, the core gameplay loop leans heavily into the standard idle gacha formula. Players assemble a team of five characters to auto-battle through stages, collecting resources and grinding levels while offline. It serves as a visually charming, casual side-scroller, though some players note that the story relies heavily on classic isekai tropes and progression eventually hits a familiar paywall.

Why Aren't My Lost Sword Codes Working?
Lost Sword codes can stop working at any time. Here are the most common reasons a code might fail and how to fix each one:
- The code has expired. Many codes have a short shelf life, sometimes lasting only a day or two. If you’re seeing an error, the code may have already been deactivated. Check the status tag next to each code on our list.
- Codes are case-sensitive. This game enforces exact capitalization — "FreEGeMs" won’t work if typed as "freegems". Copy the code directly from our list to avoid mistakes.
- Already redeemed. Codes are single-use. If you’ve redeemed a code before — even months ago — it’s permanently claimed on your account and can’t be used a second time.
- Complete the tutorial first. For Lost Sword, the code redemption feature is locked until you finish the tutorial. Play through the introductory stages, then revisit the code entry screen.
- Platform or region mismatch. With versions on iOS, Android, not every code works across all platforms. Double-check that the code applies to the version you’re playing.
- Check your in-game mail. If nothing happened after entering the code, don’t panic. Open your in-game mail or gift box — that’s where rewards are usually deposited.
