About Opti
Every creature you hatch is the only one of its kind.
Every creature has its own genome, size, pattern and serial number. Rare mutations exist, from Chromatic to the almost mythical Anomalous. The odds are real numbers, shown in the app. Be the first in the world to find something and the game remembers you forever.
Rarity, serial numbers, hatch results, breeding results and world firsts are decided on our servers using published probabilities, and never altered for individual players.
Nothing bad happens if you take a break: no starving pets, no lost streaks. Your collection lives on your account, so it is the same on every phone you sign in to.
Features
What you do in Opti
Hatch
Turn the seed, tap it, hold it until it glows, and feel it crack. What comes out has never existed before.
One of a kind
Every creature has its own genome, size, pattern and serial number. Rare mutations range from Chromatic to the almost mythical Anomalous, and the odds are shown in the app.
Raise and breed
Pet, feed, play and train to grow your bond. Breed two creatures and see what their bloodline becomes.
Collect
Fill your Codex across species, mutations, biomes, sizes and bloodlines, and show your best creatures to other collectors.
Fair by design
Opti is free. Echo Shards buy fixed items only: time skips, extra expedition slots, Discovery Paths and cosmetics. Real money never buys randomized creatures and never changes rarity odds, and a Discovery Path shows its exact before and after chances before you buy. No loot boxes.
In practice

Adults. Opti is for players aged 18 and over, and you confirm your age when you create your account.
Yes. Opti is free, with optional Echo Shards you can buy for time skips, extra expedition slots, Discovery Paths and cosmetics (the Aurora share-card palette and a brass profile frame). There are no loot boxes: real money never buys randomized creatures and never changes rarity odds. A Discovery Path, bought with shards, makes one chosen common or uncommon species more likely within its rarity tier for 7 days, and the exact before and after chances are shown before you buy.
Yes. Your collection lives on your account, so it is the same on every phone you sign in to.
Every creature has its own genome, size, pattern and serial number, and rare mutations range from Chromatic to the almost mythical Anomalous. The odds are real numbers, shown in the app. Be the first in the world to find something and the game remembers you forever: other players see each world first, linked to its discoverer. Serial numbers of deleted creatures are never reissued, so every serial stays unique.
Nothing bad. There are no starving pets and no lost streaks.
Your display name, how many world firsts you have earned, and the creatures you choose to showcase. Never your email address, purchases or balance.
Yes. Open a player's profile and tap ••• at the top right to report the collector or their name, or to block them: after a block, neither of you can see the other. A creature's name can be reported from the creature's screen. You can unblock players any time in Settings → Blocked collectors.
In the app: World tab → Settings → Delete my account. There is a 7-day grace period: sign in and choose Keep my account to cancel. After 7 days the deletion is permanent. Without the app, email privacy@nlongvity.com from the address on your account.
