A card-based RPG soaked in Slavic folklore where a young witch bargains with demons and rewrites fate. Genuinely strange, genuinely good.

Black Book is a card-based RPG rooted in authentic Slavic mythology, developed by Morteshka, a small Russian studio that clearly did its homework. You play as Vasilisa, a young woman who was supposed to marry her beloved but instead finds herself bound to a grimoire of dark power after his mysterious death. The goal is to unseal the Black Book itself, a legendary artifact said to grant any wish, by collecting its seven seals. That premise sounds familiar, but the execution leans hard into folk horror atmosphere and regional mythology that most Western RPGs never touch. Domovye, kikimory, leshy, and dozens of other creatures from Slavic tradition show up not as generic monsters but as characters with their own logic, grudges, and rules. The worldbuilding rewards curiosity: dialogue branches often expand lore rather than just move plot, and the game includes a built-in bestiary that reads like genuine ethnographic notes. Combat is deck-based. You build a hand of spells from cards acquired through progression, and fights play out in turn-based exchanges where energy management and card synergies matter more than raw numbers. It is not as deep as a dedicated deckbuilder like Slay the Spire, but it holds up surprisingly well through the mid-game. There is real build variety in how you assemble your deck, and experimenting with curse-stacking versus direct-damage approaches feels meaningfully different. The difficulty curve is gentle enough for RPG tourists but has enough teeth to keep genre regulars engaged without becoming a slog. Boss fights occasionally spike harder than the surrounding content, which can feel slightly uneven, but rarely unfair. The narrative structure mixes main-quest story beats with side quests that feel lifted directly from regional folk tales rather than generic fetch errands. This is where Black Book earns its reputation. A side story about a village plagued by a domovoi, for instance, plays out with the internal logic of actual folklore rather than game-design convenience. Choices carry weight within individual stories even if the macro narrative converges toward its ending regardless. Vasilisa herself is a quietly compelling protagonist: grief-driven, morally pressured, and written with enough nuance that her compromises with dark powers feel earned rather than edgy for their own sake. The voice acting is available in Russian with subtitles, and I strongly recommend it - it adds enormously to the atmosphere. Where Black Book stumbles is pacing. The middle third of the game leans on travel sequences and repeated minor encounters that dilute the momentum built by the stronger story chapters. The card-combat system, while enjoyable, does not evolve as dramatically in the back half as you might hope, and a few late-game abilities feel redundant rather than exciting. Players expecting the branching consequence systems of a full CRPG will also find the narrative more linear than the setup implies. Choices shape tone and unlock lore, but they rarely redirect the story significantly. For anyone who grew up on Slavic folklore, or who is tired of the same Norse-and-Celtic fantasy settings, Black Book is genuinely refreshing. It is a compact, atmospheric, well-written RPG that respects its source material and trusts the player to find it interesting without handholding every cultural reference. At its best, it feels like a fairy tale you have never heard before, told by someone who believes every word of it. Monika, Scout Team

Every store in this table quotes us in euros, so the EUR figure is the price the seller actually set, not our arithmetic — which is why EUR is also the currency we rank in. We only list an offer here when the store gives us its price in euros, so nothing in this table is a number we invented.

Pick USD, PLN, GBP, CAD or AUD in the header and we convert from EUR at the European Central Bank reference rate — converted amounts are prefixed with ~. Your bank or the store may apply a different rate at checkout. We never hide offers based on where you are: everyone sees this whole table.

We may earn a commission when you buy games through links on this page — at no extra cost to you. It never affects our rankings or verdicts.
