One day after launch, a $12 dice game from an indie studio is outselling the latest entry in one of the most storied franchises in strategy gaming. That’s not a hypothetical — that’s the Steam Top Sellers chart right now.

Rune Dice, developed by Smart Raven Studio and published by Kwalee, currently sits at #7 on Steam’s Top Sellers list as of May 20, 2026. One spot below it at #8: Sid Meier’s Civilization VII, a game with a 30-year legacy, a AAA budget, and a publisher behind it that spent decades building the brand. Civilization VII is also on a 40% sale, knocking it down to $41.99. Rune Dice costs $12.74 with its launch discount.

The numbers tell two very different stories. Civilization VII has 13,750 concurrent players — a healthy figure by most standards — but carries a Mixed rating on Steam, with only 50% of its 33,743 reviews landing positive. A player with 2,256 hours logged reported that a May 20 update left the game literally unplayable, writing that the production button “does not do anything.” Another with nearly 45 hours wrote that they had “lost all hope for Civ7 and future Firaxis Games.”

Rune Dice, by contrast, has 2,192 concurrent players surging 47.6% from its previous tracking period, and an 88% positive rating across 78 reviews. Small sample size, sure. But the trajectory is unmistakable.

How Steam’s Machine Fired

Steam didn’t leave this breakout to chance. The platform featured Rune Dice as a “Win” pick and placed it on its Specials list, giving it prime real estate in front of millions of daily browsers. For an indie launching into a crowded market, that kind of curation is rocket fuel.

The game also released with a free demo on Steam and Nintendo eShop — a low-friction onramp that clearly converted. One player who logged three hours noted they had “played the demo more than any other demo” before buying the full version.

Why the Loop Works

Rune Dice is a roguelite deckbuilder where dice have the same face on every side. There’s no luck of the roll. Instead, you fling dice across a battlefield like billiard balls — when two dice with the same number collide, they merge into a higher-numbered die, which then gets magnetically pulled toward other matching dice on the field. Chain reactions cascade. Combos stack. Your character attacks based on what you built.

Reviews across multiple outlets and player feedback converge on the same point: the merge mechanic is satisfying in a way that bypasses rational analysis. A.J. Maciejewski, reviewing for Video Chums, called it a “delightful indie that’ll have you flicking dice until the wee hours of the morning.” LadiesGamers gave it Two Thumbs Up and described the core loop as watching “half the board starts merging together like a magical domino effect.”

The game offers eight hero classes with distinct dice and abilities, procedural maps, boss encounters, and a roguelite progression system where failed runs still unlock upgrades. A player with 10 hours praised its portability: “You can fully exit the game and pick a run back up where you left out; you’re never stuck having to play.”

Both reviews noted dice physics as a weakness — occasionally failing to register a merge that looks like it should connect. Video Chums also observed that the core loop can become repetitive over longer sessions. Video Chums scored it 7.6/10, acknowledging the simplicity that makes it accessible also limits its long-term depth.

Small Games, Big Charts

The broader picture here is straightforward. Civilization VII launched in February 2025 to a Metacritic score of 79 and a player base that’s been vocal about its disappointment ever since. Rune Dice launched yesterday, costs roughly a third of Civ VII’s sale price, and is winning on momentum and word of mouth.

This isn’t about one game being “better” than another — they’re different genres targeting different audiences. But when a $12 indie dice roguelite is charting above a franchise that defined the 4X strategy category for a generation, something in the market has shifted. Players are finding more value in tight, focused loops than in sprawling ambition that doesn’t land. Steam’s curation can open the door. The gameplay has to keep people in the room.

Rune Dice is available now on PC via Steam, PlayStation 5, Xbox Series, and Nintendo Switch.
