In One Block, gems are the most valuable resource you can get. They act as the premium currency and are mainly used to unlock new classes, giving you access to better abilities and making your runs more exciting.
Unlike coins, gems aren’t as easy to farm, so knowing every way to collect them will save you a lot of time. Here’s a breakdown of all the methods to earn gems in the game. Check out our One Block Guide to Upgrade Tools and Weapon.
1. Follow the Update Events
One of the easiest ways to earn free gems is by simply following the latest game updates. Whenever a new update drops, head to the Events tab or check the in-game option, and you can claim up to 25 gems for free. It doesn’t take any grinding—just a quick tap to follow updates.
2. Survive More Days
The longer you survive in One Block, the more gems you’ll stack up. For every day you survive, you’ll receive 1 gem as a reward at the end of your run. While it might seem slow, consistent survival can really add up over time, especially if you aim for long runs without restarting.
3. Survive Raids
Every three days, raiders will attack your base. Successfully surviving these raids will reward you with 3 gems, even if you don’t manage to defeat all the raiders. This makes raids one of the most reliable methods for farming gems. The more raids you endure, the faster your gem count grows.
Earning gems in One Block requires patience and strategy. By combining update events, daily survival rewards, and raid defenses, you can steadily farm enough gems to unlock new classes without needing to spend money. Focus on surviving longer and preparing for raids, and you’ll build a solid gem income to keep progressing.
