Three games, one save file
An open world above. A dungeon below. A wallet that is really yours.
They share one adventurer, one satchel and one economy — the pet you catch in the grass fights at your side ten floors down, and everything either one earns is yours on-chain.
The Wilds
A persistent open world that is yours alone — one seeded map per account, the same every time you walk back into it. Wild creatures roam the meadows and hide in the tall grass. Weaken one in a turn-based battle, throw a soul crystal, and it is yours.
The Delve & the Tower
Ten floors of dice-driven dungeon across six difficulties, and an endless tower that only stops when you do. Walk into a monster to swing at it. Gear decides these fights — and the deeper you go, the better it drops.
Play-to-own
Every weapon, every creature, minted automatically to your own Koinos address the moment you keep it. You approve nothing and pay nothing — the signature is silent and the game covers the chain's cost. Nothing in the game is sold for money.

Adventure mode
The Wilds
Step out of the Keep into a 56×56 open world that belongs to your account. The seed is minted once and kept, so the lake, the ruins and the trader's tent are exactly where you left them — only the creatures move.
🌿 Walk in, and something walks out to meet you
Wild creatures roam the map in plain sight — walk into one to challenge it. Others wait in the tall grass, where every step is a 13% chance of an ambush. Monsters prowl here too, and those you fight the dungeon way: bump into them and swing, with your gear deciding the outcome.
Four zones ring the spawn glade — the Glade Fringe, the Deep Meadow, the Old Woods and the Far Wilds. Range further out and the creatures get stronger, rarer and richer — epics are the ceiling out here, and all but unheard of until the outer zones. Legendaries are not caught at all: two are earned by taking a line to its end, and three exist for something else entirely.
⚔️ Battles with a type chart and a real decision every turn
One of your creatures stands against the wild one. Strike for reliable damage or spend the cooldown on an elemental surge — and 14 elements push each other around, so fire scorches plant but hisses out against water. The readout tells you which way it cuts before you commit.
Switch a fresh creature in, pour a tonic down a hurt one, or flee if the fight has turned. And if nothing you own can stand? Your adventurer draws steel and fights it themselves — which is exactly how a brand-new player wins their first companion.
🔮 Catching
A wild creature at full health shrugs off a crystal. Wear it down and the odds climb — a Soul Crystal holds an uncommon creature about 45% of the time, a rare about 28% and an epic about 14% — and a Grand Soul Crystal is nearly twice as likely to hold any of them.
Both are bought with 💠 Crystals, the currency of the Wilds: pried from glowing nodes, shaken loose by victories, and dug out of chests. Spend them at the trader's tent in the glade — or at the Vendor back in town, at the same price.
Crystals
Nodes give 1–2. A won battle shakes one loose 35% of the time, rising +12% per zone out. Chests hide more. They buy every supply in the Wilds — and two of them level a legendary relic at the Forge.
Springs & fires
A hidden spring puts your whole party back to full and knits half your own wounds, then needs a while to gather its light again. The glade fire patches you up between forays. Both are free.
Leave whenever
Walking home is not a retreat: everything you caught and gathered comes with you, banked in full. The world keeps its shape for next time.
The dex
91 creatures. 46 families. One that forks three ways.
Hand-drawn, four-direction sprites — they walk beside you in the world, fight for you in battles, and lend you their abilities down in the dungeon. 43 of them spawn wild, 45 more are earned by evolving the ones you caught, and three legendaries are reserved for something else entirely.

🪶 Evolution is earned, never bought
There is no merging and no fee. A creature you fight with earns experience, and that XP carries it to Lv3. Past that it keeps learning — and when it crosses the mastery line (1,200 XP for the first evolution, 2,400 for the second) that one creature walks into the Roost and a different species walks out.
Nothing else is consumed. The one you raised is the one that changes — it keeps its shine, and its old relic retires as the new form mints. Each stage you reach also opens another perch, so a fully-grown line lets you field three companions at once.
Shinies
About 1 in 100 creatures gleams. A shiny has its own artwork — not a colour filter — its own slot in the Collection, and it passes the shine on when it evolves.
They fight for you everywhere
Your companions battle in the Wilds and act when you attack in the dungeon, each rolling its own ability. Three perches, and their effects stack.
Collect every form
The Collection counts variations, not names: plain and shiny for creatures, and every crafted grade for gear. It is a lifetime record — selling something never un-finds it.
The whole dex, in order, named — coloured by rarity: uncommon · rare · epic · legendary. 12 lines run three stages, 19 run two, and 15 never evolve at all. See every one as a table, with its stats →
The dark half
Ten floors down, and a tower with no top
Grid movement, bump-to-attack, and a d20 under every swing. There is no attack button — the step is the swing.
🏰 Six delves, one descent
Each difficulty is a different world with its own colour, its own monster strength and its own reward multiplier. Every rung is open from the start but one: The Maw stays sealed until someone has already survived the Abyss.
Every floor can turn strange: an omen bends the rules for a whole run, and a shrine offers three blessings and lets you keep exactly one.
| Difficulty | Rewards | What changes |
|---|---|---|
| Normal | ×1 | The gentle one. Learn the dungeon. |
| Hard | ×2.2 | Monsters carry innate buffs and hit 20% harder. |
| Expert | ×5 | Enemies half again as strong; rarer loot opens up. |
| Nightmare | ×8.5 | Max-level monsters, near-double strength, and more of them. |
| Abyss | ×13 | The floor of the world — the first delve where legendaries drop. |
| The Maw | ×18 | Beyond the Abyss. Sealed until you clear it. |
The Endless Tower
A boss every third floor and no ceiling at all. It changes clothes every ten floors, and from floor 13 on, every rarity tier is on the table. It always wins eventually — the question is how far you got.
The Daily Delve
One seeded dungeon a day, identical for every player, one scored attempt. Bounties run alongside it, and the podium pays.
Monster Hunts
Every kill counts forever. 10 kills of a species makes you its Hunter (+5% damage), 50 its Slayer (+10%), 250 its Bane (+15%) — permanently.
Forge · Enchant · Craft
Three workshops that turn loot into a stronger adventurer
Gear levels with gems, gains affixes by gamble, and climbs five grades by being fed copies of itself.
⚒️ The Forge — levels, and they always land
Every item runs Lv0 → Lv3, and enhancement never fails: 300, then 700, then 1,000 gems. Legendary relics ignore gems entirely and take 2 💠 Crystals a level.
✨ Enchanting
Unlocked at 10,000 AUR. 400 gems a try for a random prefix or suffix from 24 affixes — starting at a 10% chance and climbing +10% every time it fizzles, up to a 95% ceiling. Patience does most of the work that luck would.
🛠️ The Crafting Hall — two of a kind make something better
Feed the bench two fully-forged copies of an item and one better one comes out. Four copies climb two grades in a single craft; eight climb three. What goes in is gone, relics and all — so a Radiant is a real achievement, and the game can say so.
Shine only survives if every copy in the batch was shiny. Four shinies forging into one two grades up is the deepest chase in the game.
+ 2,500 AUR
+ 10,000 AUR
Grades multiply an item's whole stat line — and the top two add procs of their own.
And when you want a change
Seven more ways to spend an evening
Expeditions
Send benched heroes and idle creatures on timed trips — three parties at once. They come home with gems, gear rolls and crystals, and every level on a creature in the party adds +5% to the gems they bring back.
The Arena
Crown a champion and fight other players' champions in a server-run best-of-five. 25 gems in, 45 out on a win, an Elo ladder, ten bouts a day.
PVPD
Build a dungeon, then raid the dungeons other players built. Everyone plays both roles, with separate ratings for raiding and for dungeon-mastering.
The World Boss
A mountain of HP for the last three days of every month, which everyone holding 500 AUR chips at together. You are expected to die; your best damage is your score, and the board pays AUR.
Knucklebones
The Gambler Ghost deals a real dice duel on a 3×3 board — match values to multiply them, and destroy the same value in his column. Wager 50 gems of the run's haul.
The NFT Market
Trade relics with other players. A smart contract escrows the relic and settles the sale atomically — 90% to you, 10% to the treasury. Whoever holds the token owns the item, in-game too.
Weekend ladder
Friday to Sunday, your best winning delve on Hard or deeper takes the board. The top of it splits a real AUR prize pool.
The Web3 part, which you can ignore entirely
Everything crypto normally asks of you is gone
No wallet extension. No seed phrase. No gas. Nothing to buy in. You sign in like any normal game — and a real Koinos account is created for you behind the scenes.
What money buys — and what it doesn't
The shop sells exactly two things: gems, and an Expedition Pass. That is the whole list, and it always has been. No item is sold for money — not a weapon, not a creature, not a level.
The Pass is a real advantage and we would rather say so than pretend otherwise: +25% gems on every run, a daily AUR claim, and a small chance of an item along with it. What it is not is a private shelf — everything it can give you drops for everyone else too.
Gear at the Vendor is priced in AUR, the token you earn by playing. You can buy AUR from other holders if you would rather skip the grind, and some people will. Nothing you can reach that way is closed to a player who never spends a penny.
No gas. Really.
Koinos runs on mana — a resource that regenerates instead of a fee that burns. The game's wallet pays it for every player through mana sharing.
So there is no gas popup between you and the dungeon, no balance to top up before you can play, and no transaction you have to understand. It is a Web2 experience with Web3 underneath it.

Bring a friend — you each earn 1,000 AUR
Share your invite link. Once your friend has genuinely played — three delves, the Tower to floor 3, delve floor 5, fifty monsters and their first on-chain relic — you both get paid. Every one of those is checked against runs the server itself recorded, so nobody can claim it without playing. Funded by 2,000,000 AUR set aside for it, first come first served, and it closes when the fund is spent.
Straight answers
Questions people actually ask
Do I need a crypto wallet?
No. Sign in with Google or an email address and a real Koinos account is made for you. Those two routes are convenience accounts: the game holds the key for you, encrypted, which is what lets the same account follow you to any device. You can export it any time in Settings and take the account with you — the account itself never depends on us.
Is it really free? What's the catch?
It is free, and the game pays every chain fee for you. The shop sells gems and an Expedition Pass — and nothing else. The Pass is a genuine leg up (+25% gems, a daily AUR claim, and the odd item), so it is not nothing; what it is not is exclusive. Every item it can hand you also drops for players who never spend anything.
What does "the NFT is the item" actually mean?
Every non-consumable you own is minted as a token to your own address, with its level, grade, affixes and shine written on the token itself. Whoever holds it owns the item in-game too. Sell it on the marketplace and it leaves your satchel; buy one and it appears there.
Where do creatures come from?
The open world, and only there. 43 species roam the map and hide in the tall grass; you weaken one in battle and catch it with a soul crystal. Another 45 are the evolved forms — never found wild, only earned — and three legendaries are held back for something else entirely. The dungeon drops gear and gems; it has not dropped a creature since the Wilds opened.
How do I evolve one?
By fighting with it. Battle XP carries a creature to Lv3, and past the mastery line it evolves at the Roost — one creature transforming, nothing merged, nothing charged.
Can I play on my phone?
Yes — it is built phone-first and installs as an app from your browser's menu (Add to Home Screen). Your account follows you across devices, so you can delve on a phone and forge on a laptop.
Do I lose everything if I die?
Not much. Dying costs 40% of the loose gems from that outing — in the dungeon and in the Wilds alike. Everything else is safe: items you picked up are yours, and creatures you caught stay caught.
The grass is rustling.
Two minutes from now you could be naming your first companion. There is nothing to install and nothing to pay.
