Dungeon Odyssey

Review by eFreeware

Dungeon Odyssey is a free idle role-playing game from Super Planet, built on the web comic of the same name. The comic is credited with 21.7 million cumulative views, and the game retells its central story: Kim Jinwoo, born in the deepest reaches of an underground dungeon, rising from a lowly cave-dweller to king of the labyrinth. It sits in the Role Playing category on Google Play, carries an Everyone rating and has passed 100,000 installs with a 4.6 average from 4,680 ratings.

The main reason to consider it is how little it asks of your hands. Combat runs on a few taps before the growth continues on its own. For anyone who already follows the comic, the draw is the cast: 18 characters from the series appear, among them the loyal servant Dominique, the under-elf princess Rikshasha and Angela, and part of the game is freeing those allies from a curse.

It is worth setting expectations early. This is an idle game with ads and in-app purchases. The appeal is incremental numbers going up in a world you already recognize, and the review below looks at how that loop is put together.

Taps, auto-growth and a boss every hundred floors

The core loop is deliberately shallow at the surface. You tap a handful of times, the fight takes over, and your character keeps growing without further input. Waves of enemies arrive one after another, and every 100 floors a giant boss blocks the way. That rhythm gives the game a clear sense of forward motion without demanding attention for long stretches.

Between fights, the growth systems do the real work. Equipment is summoned and merged, relics are gathered, and elemental skill builds come together. The growth is meant to run alongside the labyrinth itself, and the numbers you accumulate feed directly into how far you can push.

The twist that separates this from a plain idle grind is what happens when you stall. Instead of hitting a wall and waiting, you can trade all your power for labyrinth upgrades, then use the strength you gain from that to descend further. It turns a dead end into a decision about when to cash in and start climbing again.

I would expect the first hours to move quickly, since idle games of this shape tend to hand out early progress generously enough to teach the systems. The longer-term pull is the merge-and-build layer, where choices about equipment and elemental skills start to matter more than raw tapping.

Daily runs, the Citadel and Labyrinth War

Beyond the main climb, the game spreads its content across several named modes. The content includes a daily labyrinth run, an Overlord's Citadel, a Trial of the Abyss, an Underground Vein and a Labyrinth War. Each gives a different frame for the same underlying growth, which is a sensible way to keep an idle game from feeling like one long corridor.

The developer presents these as trials to overcome on the way to becoming king of the labyrinth, and that framing fits the source material. Daily Labyrinths in particular suggest a routine you return to, while the Citadel, the Trial of the Abyss and the Underground Vein read as more structured challenges. Labyrinth War is another of the named modes.

The 18 collectible characters tie into this. Freeing allies from their curse gives the roster a purpose beyond a gallery, and fans of the comic will likely recognize the names before they see the art. I would treat the roster as the long-term collection goal that runs alongside the floor count.

The game was released on August 2, 2026, and the most recent update on October 7, 2026 added new content and resources along with minor error fixes. That is normal for the genre and worth factoring in if you prefer a game that stays put.

Ads and purchases in a free idle game

Dungeon Odyssey is free to download and contains ads, and it offers in-app purchases.

What matters practically is that a free game with ads and purchases is a different commitment from a paid one. If you dislike ads or in-app purchases, that is a real consideration before you install.

The content rating is Everyone, which fits a game built on tapping, merging and collecting rather than anything graphic. The comic's dark underworld setting is the backdrop, though the rating stays broad.

My advice is to treat the free download as a trial of the loop itself. If the tapping, merging and floor climbing hold your interest, the presence of ads and purchases is worth knowing about.

Readers of the comic and idle-game regulars

The clearest audience is people who already know Dungeon Odyssey as a comic. The 21.7 million cumulative views suggest a sizable readership, and this game is built to let that readership play through Kim Jinwoo's journey rather than just follow it. Recognizing Dominique, Rikshasha, Angela and the rest is a large part of the pleasure here.

The second audience is idle-RPG players who want something to check in on. One-handed combat, automatic growth and a boss every 100 floors make it easy to pick up for a few minutes and put down again. If your favorite part of the genre is watching a build come together through equipment merges, relics and elemental skills, this offers that without requiring long sessions.

It is less suited to someone looking for a hands-on action RPG or a narrative game with heavy dialogue. The story of the comic is the setting and the goal. Conquest, collection and growth are the focus, and that is what it delivers.

The 4.6 average across 4,680 ratings is a reasonable signal that the loop lands for the people who try it, though ratings from a game this young say more about first impressions than long-term staying power.

A steady climb for comic fans and idle players

Dungeon Odyssey does one thing clearly: it turns a popular web comic into an idle RPG you can push forward with a few taps. The floor-by-floor climb, the boss every 100 floors and the option to sacrifice your power to upgrade the labyrinth give the loop a shape beyond simple waiting, and the 18 characters from the series give it a face.

The trade-offs are straightforward. It is free with ads and in-app purchases, and it is built around automatic growth rather than active play. The comic's plot is woven into the collection and progression.

If you read the comic and want more time in that world, or you enjoy idle games with merging, relics and elemental builds, this is a sensible one to try. Install it for the loop, not for the plot, and the free download will tell you quickly whether the climb holds your attention.
