Rune Dice Steam Demo Review
Verdict: Play
Rune Dice nails the chain reaction fantasy and gets more layered the deeper you go.
Rune Dice is a roguelike deck builder from Smart Raven Studio where you launch dice across a board, matching numbers merge and spring into more matches, and the chain reactions deal damage to enemies fighting above. It looks simple in the first few minutes. It is not simple for long.
Rune Dice is a roguelike deck builder where you launch dice across a board to trigger merges and chain reactions. Each class brings its own abilities, and the rogue's backstab mechanic was a standout in the demo. The game grows more layered as a run develops, making it clearly suited to PC over mobile.
Pros
- Satisfying chain reaction mechanic
- Multiple classes with distinct abilities
- Strong Steam reception at 93% positive
- Free demo available now
Cons
- Combat ball can be easy to miss
- Dice ricochet occasionally unpredictable
- Early impression undersells its depth
First impressions
I am a dice goblin and this was made for me. I saw it on X and clicked play immediately. That instinct turned out to be correct, which does not always happen.
The first few runs feel close to a mobile game. Simple board, simple decisions, satisfying feedback loop. That impression does not last. The longer a run goes the more layers accumulate, and by the time you are deep into a good run the number of things happening simultaneously makes it clearly a PC game. I went in expecting something casual and came out wanting to optimise.
The chain reaction
The chain reaction is the thing. You launch a die across the board, it hits a matching number, they merge, the merged die springs toward another match, that merges too, and so on until the board settles. The higher the value on the merged dice, the more damage dealt to enemies above.
When it all goes off at once the screen fills with movement and numbers. It is deeply satisfying in a way that is hard to explain until you have seen it happen.
Class and map structure
I played mage and rogue in the demo. Each class has its own specific dice abilities on top of the general ones available to everyone. The rogue has backstab, which lets you target high damage dealers in the enemy back line before they can act. That alone made rogue my preferred class. Removing the biggest threat before it fires changes how you approach every fight rather than just adding a damage number.
Between fights you pick a reward: a new die, healing, or a buff. The map has branching paths, shops, shrines, harder battles, chests, and a final boss at the end of each area. Completing specific achievements unlocks higher level starting characters and additional classes, which gives you a reason to keep running even after you understand the system.
Small issues and verdict
The battle happening above the board is easy to miss when you are focused on the dice below. It is small and the action on the board is more visually immediate. Worth consciously checking what is happening up there, especially in longer fights.
The ricochet of the dice does not always go where you expect. That might be the game. It is probably a skill issue on my part. Either way it catches you out in the early runs.
Steam sits at 93% Very Positive overall from over 300 reviews, and 96% Overwhelmingly Positive recently from 119. The full game is coming soon, which makes now a good time to try the demo before it goes away. Download it if you enjoy chain reaction mechanics and want something that rewards figuring out how the pieces interact.
