Clash of Clans features multiple in-game currencies but Gems are one of the most valuable.
You can use Gems for builders, quickly finishing your upgrades, hero skins, and buying many useful items. However, they are not as easy to get when compared with Gold or Elixir.
The good news is that you can get hundreds of Gems for free with regular gameplay. The process is slow but you can still collect a lot of Gems without spending a penny.
1. Completing Achievements
Completing achievements is one of the best ways to get free Gems in Clash of Clans (CoC).
High achievements even reward you with 1000 Gems. Achievements in CoC include attacking, donations, defences, or Clan activities.
For example, the War Hero achievement rewards you for earning stars in Clan Wars. Reaching 1,000 stars can reward you with 1,000 Gems. Similarly, War League Legend offers 250 Gems for earning 250 Clan War League stars.
- Clan Games (Monthly)
Clan Games arrive every month in CoC. You can participate along with your clan members to complete tasks and reach higher reward tiers. When the games are complete, you are allowed to choose from multiple rewards. Free Gems are one of them. It often offers you with 20, 40, and 100 Gems for the final reward tier.
If you reach the maximum individual points, you also get the access to an additional reward choice when your Clan unlocks enough tiers.
- Gem Mine (Builder Village)
Gem Mine is slow but gives you a consistent supply of Gems. This passive Gem source is in the Builder Base. Unlike other methods in this list, you don’t have to complete anything for collecting Gems regularly.
You can get 2-5 Gems daily depending on the building level. For example, a level 8 Gem Mine gives you 4.3 Gems daily with a storage capacity of 17 Gems. However, you need to collect them regularly before your storage becomes full.
- Clearing Gem Boxes and Obstacles
Cleaning up your bases (Home Village and Builder Base) from obstacles also sometimes rewards you with free Gems. Obstacles like trees, trunks, and bushes appear naturally on the edges of your village. On clearing, you get EXP and Gems for free. However, the rewards vary.
Gem Boxes are particularly valuable obstacles because each one contains 25 Gems.
- Selling Extra Gold / Elixir / Dark Elixir
When your resource storage becomes completely full and you still have monthly or special event Gold, Elixir, or Dark Elixir rewards available to collect, you can exchange them for Gems. For monthly pass rewards or special events rewards CoC offers Gems for the resources you cannot add to your resources. However, the exchange is usually 5 Gems for any amount of excess resource.
- Selling Magic Items
Selling extra or unwanted magic items also gives you free Gems. You can find them in your Magic Items inventory. For example, selling a Resource Potion rewards you with 10 Gems. Hammers are more valuable so you get 100 Gems when sold.
Magic Items are valuable, and you often spend Gems to purchase them. But this method allows you to sell an unwanted item and buy a required item with Gems.
- Bonus Track on the Supercell Store
The Supercell Store offers Bonus Track to get 100 Gems every month. You need to complete simple missions to earn the points which unlock the Gems reward. The higher your points, the more Gem rewards you can unlock. However, this is time-sensitive so you should keep checking Bonus Track regularly before missions expire.
- Trading Medals For Gems
Medals also offers you a way to collect Gems for free in CoC. This method involves purchasing Magic Items first from the Trader and then selling them for Gems. You can do this using Raid Medals and League Medals.
- Limited-Time Town Hall Events
Sometimes Supercell introduces limited-time events for Town Halls. It usually involves attacking pre-built bases or trying out a strategy. If you successfully complete the attack and get 3 stars, you get the free Gems reward. You can try multiple times to adjust the attack strategy.
For example, the current Last Town Hall 18 Challenge rewards you with 25 Gems, 400 XP, and a Power Potion.
