There is a particular pleasure in discovering a strategy game that starts with a handful of modest options and gradually lets you build something utterly ridiculous. One moment, you are carefully managing a few cards and trying to keep a battle under control. A few encounters later, your carefully assembled combinations are triggering one another in spectacular fashion, your pawns are becoming terrifyingly powerful, and the numbers on screen have grown so large they almost seem to be taking the mickey. Cubic Cosmos is built around that wonderfully addictive transformation, taking the familiar foundations of a roguelike deckbuilder and pushing the idea of growing stronger with every decision to delightfully excessive extremes.
Developed and published by Inkstone Atelier in partnership with Lilith Games, Cubic Cosmos is a fast-paced card battler that challenges players to build an army of pawns, combine abilities and assemble a deck capable of demolishing increasingly formidable opponents. Its premise revolves around a mysterious goddess and a seemingly endless cycle of cosmic combat, with each run offering another opportunity to find a way forward. There is a narrative framework here, but the real attraction is mechanical rather than literary. This is a game about experimenting, spotting opportunities, making clever decisions and watching a collection of seemingly ordinary cards become an unstoppable engine of destruction.
For fans of roguelike deckbuilders, that promise is immediately appealing. The genre thrives on the tension between careful planning and unexpected opportunities, and Cubic Cosmos appears particularly interested in the moment when a decent strategy becomes absurdly effective. With more than 240 cards, over 50 equippable Relics, 12 unlockable heroes and multiple difficulty settings, there is plenty of scope for experimentation. The challenge is not simply to win a battle, but to discover just how far you can push your chosen strategy before the game finds a way to push back.
Building an Army One Card at a Time
At the heart of Cubic Cosmos is building a powerful deck, but the experience extends beyond simply collecting cards with impressive numbers. Players assemble an army of pawns, develop their attributes and combine their abilities to create synergies that can transform the flow of a battle. Individual cards have their own uses, but their true value often emerges when they work alongside other pieces of the deck. A seemingly modest ability can become the key component in a devastating combination, provided you have built the right foundations around it.
That emphasis on synergy is one of the genre’s greatest strengths, and Cubic Cosmos appears determined to make it the centrepiece of its design. Rather than treating every card as an isolated attack or defensive option, the game encourages players to think about how their abilities interact. One effect can trigger another, buffs can strengthen subsequent actions, and the right sequence of plays can produce an outcome far greater than the sum of its parts. When those interactions come together, the satisfaction comes from understanding why the strategy worked, not merely from watching an enemy lose a large amount of health.
The game’s lane defence elements add another consideration to the usual deckbuilding formula. Positioning and the way pawns operate together can influence how effectively a strategy deals with the opposition, giving players more to think about than simply choosing whichever card produces the largest immediate number. This helps create a tactical dimension beneath the game’s extravagant damage potential. The most successful players will need to recognise which pieces of their army deserve investment, how their abilities complement one another and when a particular combination is worth building an entire run around.
Of course, assembling a perfect deck is rarely a straightforward process in a roguelike. The cards, Relics and events available during a run can encourage you towards a strategy you had not originally intended to pursue. Sometimes the smartest decision is to strengthen an existing combination, while on other occasions a newly discovered effect might offer a better route to victory. That uncertainty is essential to keeping repeated runs interesting, because a game that allowed players to construct the same perfect deck every time would soon lose much of its appeal.
The Joy of Absurdly Powerful Combos
Cubic Cosmos distinguishes itself through its emphasis on persistent stat scaling and the extraordinary potential of its card combinations. Many deckbuilders ask players to work within relatively strict limits, with cards providing predictable amounts of damage or temporary improvements that expire at the end of a turn. Here, the emphasis is on allowing power to accumulate throughout a run, with permanent upgrades and compounding effects capable of turning modest attacks into devastating weapons. The prospect of dealing damage in the hundreds, thousands or even millions gives the game a wonderfully over-the-top personality.
There is something deeply satisfying about this approach when it is supported by meaningful decisions. Watching a pawn grow stronger because you have invested in the right upgrades gives each encounter a sense of progression, while a carefully assembled chain of abilities can reward several turns of planning in a single explosive sequence. The most enjoyable moments in games like this often arrive when a strategy finally clicks into place. You recognise an interaction you might have overlooked earlier, make the necessary adjustments, and suddenly find yourself dismantling opponents who previously seemed impossible to defeat.
The potential for long chains and repeated turns is particularly exciting. A well-constructed deck can create situations where one action sets off a cascade of additional effects, with every trigger contributing to an increasingly devastating result. These moments can make a player feel less like someone playing cards and more like an engineer who has finally got a complicated machine running exactly as intended. When a game encourages experimentation and then rewards it with spectacular results, it becomes remarkably difficult to put down.
There is, however, a delicate balance between allowing players to feel powerful and making that power too easy to achieve. If upgrades and damage multipliers become excessive without requiring much thought, the tactical challenge can eventually disappear beneath the numbers. Cubic Cosmos will be at its strongest when players must work for those enormous combinations, weighing immediate gains against long-term improvements and deciding which synergies deserve their attention. Its power fantasy is an appealing selling point, but the decisions leading up to that fantasy are what can sustain it over dozens of hours.
Twelve Heroes and Plenty of Ways to Play
Variety is essential in a game built around repeated runs, and Cubic Cosmos offers a substantial selection of unlockable heroes. Its 12 characters are spread across three classes, each with unique abilities that can influence how a deck develops and how players approach combat. Different starting strengths and special mechanics can encourage different priorities, meaning that a strategy that performs brilliantly with one hero may require considerable adjustment with another. This gives the game a reason to be revisited beyond simply trying to beat a previous high score.
The appeal of distinct heroes lies in the way they alter the player’s thinking. Some runs might encourage aggressive combinations designed to overwhelm enemies quickly, while others may reward a more measured approach focused on strengthening pawns and exploiting the relationships between cards. Discovering these differences can be as enjoyable as unlocking the characters themselves, particularly when a new ability opens up a strategy that had not previously seemed viable. It also encourages players to move beyond their favourite combinations and explore the wider possibilities available.
The card pool provides another substantial source of variety. With more than 240 cards and over 50 Relics, there are numerous potential combinations to investigate, although the sheer size of a collection is only valuable when its individual components have a purpose. Relics are particularly important because their effects can shape an entire run, encouraging players to adapt their deck around the bonuses they acquire. A useful Relic might reinforce an existing plan, while an unexpected one could tempt you into building something entirely different.
Random events add further unpredictability between encounters. These moments can introduce opportunities, complications or decisions that change the direction of a run, helping prevent the overall experience from feeling like a repetitive march through identical battles. Not every random outcome will necessarily be favourable, but uncertainty is part of what makes the roguelike structure work. The important thing is that players should feel capable of responding intelligently to whatever the game presents, rather than being entirely at the mercy of luck.
A Challenge for Every Kind of Strategist
Cubic Cosmos offers several ways to test your abilities, from its endless adventures to daily challenges and more demanding difficulty settings. The availability of fixed and random boss encounters provides both familiarity and surprise, allowing players to practise against known threats while staying alert to the unexpected. Daily challenges are a welcome addition for anyone who enjoys a specific objective to pursue, particularly when the usual freedom of a roguelike can make choosing a direction surprisingly difficult. A defined challenge gives each session a clearer purpose.
The scaling difficulty system, which offers more than ten levels, should provide a useful progression path for players who become comfortable with the basic mechanics. A deck that comfortably handles early encounters may struggle when enemies become tougher and mistakes carry greater consequences. Higher difficulties can also expose weaknesses that are easy to overlook when the player is simply overwhelming everything in their path. They encourage a deeper understanding of card interactions, resource management and the value of building a strategy that can survive an unfavourable draw.
Mastery Mode takes that philosophy further by putting carefully developed decks under additional pressure. It is an appealing idea for players who want their understanding of the game tested beyond simply reaching the end of a successful run. Building a powerful combination is one thing, but knowing how to use it when the opposition becomes more demanding is another. A mode dedicated to testing that knowledge gives experienced players a reason to keep refining their strategies long after the initial novelty has worn off.
The range of modes also helps accommodate different moods. Sometimes you want a relaxed run in which you experiment with an unfamiliar combination, while on other occasions you want a serious test that forces you to make the most of every opportunity. A good deckbuilder should support both approaches without losing its identity, and Cubic Cosmos has the ingredients to do just that. Its long-term appeal will ultimately depend on how well its difficulty and random encounters continue to challenge players who have already learnt its most effective tricks.
Presentation That Knows Where to Focus
Cubic Cosmos appears to place its priorities firmly on mechanics, and that is not necessarily a criticism. In a card battler, clarity and responsiveness matter enormously, especially when a single action can trigger a chain of effects that shift the state of a battle. Smooth input buffering is a welcome inclusion, suggesting attention to the practical experience of playing rather than merely the theoretical possibilities of the card system. When players are constantly making decisions, a responsive interface can make the difference between a satisfying tactical flow and an unnecessarily cumbersome experience.
The cosmic premise gives the game a broad fantasy framework, but its narrative is relatively minimal. The mysterious goddess and the cycle of combat provide a reason for the repeated battles, yet the story does not appear to be the main attraction. Players seeking rich character development, extensive worldbuilding or a sweeping science fiction narrative may find the setting underexplored. However, those who prefer their card games to focus on strategy rather than lengthy dialogue are unlikely to consider that a major drawback.
There is a trade-off here. A stronger narrative could have given the different heroes and cosmic encounters more emotional weight, making each victory feel like a meaningful step towards breaking the cycle. On the other hand, keeping the story in the background allows the gameplay to maintain its momentum, with fewer interruptions between the player and the next strategic decision. Cubic Cosmos seems comfortable making that choice, and its success will depend on whether the card system provides enough depth to compensate for the limited storytelling.
For a game whose main appeal lies in experimenting with combinations, that focus is understandable. The numbers, triggers, upgrades and the changing possibilities of each run are intended to provide the drama. It may not leave players thinking deeply about its characters or lore, but it has a more immediate objective: to make the next battle irresistible and the next combination even more satisfying than the last.
Final Verdict
Cubic Cosmos has the makings of a thoroughly addictive roguelike deckbuilder, particularly for players who enjoy finding unusual synergies and turning a modest collection of cards into a machine of spectacular destruction. Its combination of pawn development, lane defence, permanent upgrades and chain reactions gives it a distinct flavour, while its extensive card pool, unlockable heroes and varied game modes provide plenty of reasons to return. The promise of building combinations that deliver astronomical damage is certainly entertaining, but the real attraction is the strategic tinkering required to make those combinations work.
Its minimal storytelling may leave the wider universe feeling underdeveloped, and the focus on ever-increasing power will need to be balanced carefully to ensure that battles remain challenging rather than becoming a procession of enormous numbers. Nevertheless, Cubic Cosmos understands the appeal of a well-designed deckbuilder: every run offers another chance to discover something new, every upgrade can change your plans, and every successful combination makes you wonder what else might be possible. For tactical card fans, that sense of experimentation and escalating power could prove difficult to resist.
