Knockout League codes and their importance

Unlock better Trainers by using Gems in Knockout League (Image via Roblox)

Roblox promo codes for Knockout League are extremely useful because they give free Gems. Players save time that would have otherwise been spent grinding for the in-game currency. With Gems, you can unlock new Trainers that increase the strength gains for different workouts. However, a few Trainers can only be unlocked by using Robux, while some are part of daily log-in rewards.

Knockout League code troubleshooting [How to fix]

Be mindful of the letter casing when entering codes (Image via Roblox)

Given that codes for the Roblox game are case-sensitive, copying and pasting them into the redemption box is a better option than typing them. A mistake in the letter casing before hitting "Redeem" will result in an error. Moreover, you will face an error when trying to use a code twice. Remember that each code can be redeemed once in Knockout League.
