How it plays
READ EVERY MOVE
Every awake monster shows its intent: an attack and its damage, a ranged shot, a charge along a line, a blast, a summon. Walls block sight and ranged attacks, and you choose the target of your cards. Telegraphed attacks can be dodged, so where you stand matters as much as what you play.
HOW A TURN WORKS
Tap a tile to walk, tap a monster next to you to attack. Your hand of five cards spends energy; block soaks damage until the turn ends. Take the stairs to go deeper.
FIVE STRATA, FIVE BOSSES
Five strata of five floors each: lantern-lit catacombs, a drowned archive, fungal hollows, a forgotten forge and the heart of the Cipher. Every stratum brings new monsters and ends with its own boss, and every boss warns you before it strikes. From floor 3, elite monsters may appear: defeat one for a relic or a card upgrade, or leave it be.
BUILD YOUR DECK
After each floor, pick one of three cards or reroll. 40 cards you can upgrade and 24 relics that change how a run plays out. Shrines let you upgrade a card, remove a card or heal. Chests hold gold plus a potion, a card scroll or a chance at a relic. A wandering merchant waits on the third floor of every stratum to take your run gold.
Wick, a small living lantern, lights the way on your first floor.
Three heroes
Warden
Thick armour, solid block. Tough and forgiving.
Arcanist
Ranged spells, low health. Positioning is everything. Unlocks on floor 3.
Shade
Hit hard, leave fast. For experts. Unlocks on floor 7.
Between descents
ALWAYS A NEXT GOAL
Echoes from every run buy permanent upgrades. Delver Rank (1–50) and Hero Mastery (1–10 for each hero) bring new cards and relics into your drafts. The Codex records every monster, card and relic you discover. Reach the bottom to open Ascension 1–10. 18 achievements to earn.
DAILY AND WEEKEND
The Daily Dive gives every player the same dungeon and a rule of the day. On weekends the Echo Tide adds bonus echoes to every run (from Delver Rank 5). Daily rewards, daily missions, a leaderboard and statistics.
YOUR RUN IS SAFE
Your run is saved at the end of every turn. Close the game at any time and continue your descent from the same floor.
Fair play
Free to play — optional in-app purchases, contains ads
Every stratum, hero, card and relic is unlocked by playing. The Delver's Pass is optional: it removes ads and adds conveniences such as bonus echoes, a free continue each run and a free card reroll each floor. Optional in-app purchases. Contains ads: banners on menu screens only (never during a run or in the store), an occasional full-screen ad between runs, and no ad when the game opens. Rewarded videos are always your choice.
PRIVACY
No account and no sign-in. Your progress is kept on your device; leaderboard entries (an optional name and your score) are stored on our server. Ads are served by Google AdMob, with a consent choice where the law requires it. Anonymous gameplay analytics can be switched off in Settings, and the game does not record your screen.
