To earn free Diamonds in Infinity Nikki, work through available quests and exploration, claim daily and achievement rewards, and check the in-game Events screen for limited-time activities. What is available depends on your story progress and the current version. The official notices cited here do not establish an active redemption code or a fixed Diamond total for October 4, 2026, so treat old code lists and earning estimates with caution.
Start with quests and story progress
Quests and story content are a direct route to rewards: official announcements describe quests that grant Diamonds and other items. Some events and features require progress through a particular main-story chapter or world quest before they unlock. Check each activity’s stated requirement in the game rather than assuming it is available from the start. Official event notice Official version notice
Explore newly available regions
Exploration can bring rewards as you open regions and collect items such as Whimstars. Official version notices describe rewards tied to exploration, but that does not mean every collectible awards Diamonds. Check the reward description for each activity and prioritize areas currently accessible to your account. Official version notice
Claim daily tasks and achievements
Look at the daily task interface regularly: an official notice describes daily tasks that award Diamonds and growth materials. The Courses interface is also worth checking for achievements, including region-specific achievements added in version updates. The notices do not establish a current guaranteed Diamond amount, so rely on the in-game reward display for what you can claim. Official version notice

Check challenges and permanent features
Mira Crown activities and other challenges can offer rewards, but their unlock conditions and reward details can vary with the version. Open the feature in-game and review its requirements and reward list before spending time on a challenge. Official event notice Official version notice
Prioritize limited-time events before they end
Event rewards are temporary and can involve an exchange currency rather than direct Diamond payouts. For example, the September 2026 Sunlit Rendezvous event let players collect Sunward Seeds and exchange them for rewards including Diamonds; it ended September 23, 2026, so it is not a current offer on October 4. Other activities described in the Version 2.8 notice had different dates and story requirements. Official event notice Official version notice
- Open the in-game Events screen and check which activities are currently available.
- Read the event’s story prerequisite, task requirements, reward list, and end date.
- Claim earned rewards and exchange event tokens before the deadline; do not assume unclaimed rewards remain available afterward.
Use current official sources to verify redemption codes
No currently valid code for October 4, 2026 is established by the official notices cited here. Codes are time-limited, so a code appearing on an older list may have expired. Before trying one, confirm it in a current official announcement and check any stated region, account, or expiry conditions. Official announcements
Why there is no reliable fixed Diamond total
The documented opportunities depend on the game version, which regions and story content you have unlocked, and whether you complete limited-time activities. The cited official notices do not establish an aggregate free-Diamond amount per day or update. Check the reward details in your own game rather than planning around an unofficial total.
Keep free rewards separate from paid currency
If your goal is to earn rewards without paying, focus on the in-game activities above. A top-up is a purchase, not a free-reward method; avoid third-party sellers claiming to provide free Diamonds.
