Deck-Building Game Localization
Native translators. Genre expertise. LocQA included. Get a free quote →
Deck-building games — from Slay the Spire-style roguelike deckbuilders to digital CCG adaptations to collectible card games — have become a beloved genre with passionate international communities. The genre’s localization challenges are distinctive: card text requires extreme precision because ambiguous wording creates gameplay exploits; keyword systems must be internally consistent across hundreds of cards; and card-space constraints mean translations must be both accurate and brief. SandVox provides deck-building game localization for studios targeting international card game and deckbuilder communities.
Unique Localization Challenges
- Card text precision — card effect text must be unambiguous; any vagueness creates gameplay disputes and community frustration
- Keyword consistency — game-specific keywords (Exhaust, Ethereal, Retained, etc.) must be translated consistently across the entire card set
- Text box constraints — card text has strict character limits; translations must be accurate AND short enough to fit the card layout
- Rules language — card game rules text uses very precise, standardized language conventions that differ from narrative game writing
- Large card sets with updates — deck-builders regularly add new cards; each expansion requires consistent application of established keyword and formatting conventions
What We Localize
- Deck-building game translation by gaming linguists with card game and deckbuilder genre expertise
- Card keyword glossary development with cross-card consistency enforcement
- Card text rules language adaptation for precision and natural expression in target language
- Text box fit optimization for translated card text within card layout constraints
- In-engine LocQA for card text display, tooltip formatting, and collection UI
Our Process
- Keyword glossary — all game-specific keywords, status effects, and mechanical terms established before card translation begins
- Rules text language guide — conventions for expressing game mechanics (targeting, resolution, etc.) in target language established
- Card translation with keyword consistency checking against established glossary
- Text box fit review — all translated card texts verified for character limit compliance
- In-engine LocQA testing card display, tooltip interactions, and collection filtering UI

Frequently Asked Questions
How should deck-building games handle game-specific keywords across translations?
Game-specific keywords in deck-building games require systematic treatment: (1) Establish keywords first — before any card translation begins, all keywords, status effects, and mechanical terms must be translated and approved. These form the foundation for all subsequent card translations. Changing a keyword mid-project means retroactive changes across all cards using that keyword. (2) Keyword translation approaches — the two main approaches are: (a) translate the keyword to a target-language term (Exhaust → Ausblenden/Exaustion in German) or (b) localize the keyword while keeping game-recognizable structure (keywords that are bolded proper nouns may be left in English with localized explanation in tooltips). Approach depends on the game’s design philosophy. (3) Community standardization — for games with established communities, check whether players already use community translations for keywords; deviating from established community vocabulary creates confusion. (4) Tooltip expansion — card text is limited, but tooltips can explain keyword mechanics in more detail; the keyword term itself needs to be short, but the tooltip explanation can be fuller. (5) Consistency enforcement — use TM with keyword flags; when a translator reaches a card with a keyword, the TM should surface the approved keyword translation automatically.
What makes card text localization different from narrative game localization?
Card text localization is functionally a precision technical writing task, not a narrative creative task: (1) Legal-grade precision — card effects must be unambiguous in the target language. A vague translation creates player disputes (‘Does X happen before or after Y?’). The standard is: if a native speaker reads the card, they should understand exactly what it does with no ambiguity, in exactly the same way as the original. (2) Register — card text uses a specific impersonal register (‘Deal 5 damage to an enemy’, not ‘You deal 5 damage to one enemy’); this register convention must be consistent across all cards and match the game’s own style guide. (3) Space constraints dominate — translation creativity is severely limited by text box space. A translator who produces perfect literal accuracy in three sentences when the text box fits two must find a shorter equivalent, not just translate. (4) Rules interactions — card text often contains rules terminology that has specific legal meanings in the game system (timing, targeting, resolution order). Translators must understand these rules implications to translate accurately. (5) Playtest review recommended — having native-speaking players review translated card text for gameplay clarity (not just language quality) is valuable for competitive or complex deck-builders.

Frequently Asked Questions
Deck-building games (Slay the Spire, Dominion, Monster Train) share card game localization challenges: precise mechanical terminology, consistent keyword usage across all cards, and high string density. The deck-building genre also features upgrade mechanics, synergy descriptions, and meta-game text (run results, statistics, unlocks) that must be accurately localized. Card effect text in inflected languages (German, Russian, Polish) must use correct grammatical forms for every referenced game object. SandVox builds terminology glossaries before any deck-building game localization and enforces keyword consistency across all cards and UI.
A typical indie deck-builder (200–500 cards, 20,000–50,000 total words) into Japanese costs approximately $3,600–$17,500. Into German approximately $2,400–$11,000. Popular deck-builders like Slay the Spire and Monster Train have been localized into 10+ languages — their commercial success demonstrates the strong ROI of localization for the genre. SandVox offers deck-building game packages that include card text, UI, run result text, achievement descriptions, and ongoing DLC content localization.
Deck-building games have particularly strong audiences in: Japan (Slay the Spire is enormously popular among Japanese indie game players), Simplified Chinese, Germany, South Korea, France, Russia, and Brazil. The genre’s strategy depth appeals to engaged, high-spending players in all these markets. Japanese is consistently the highest-ROI localization for indie deck-builders. SandVox recommends JA, ZH, KO, DE, and FR as the core languages for deck-building game localization.
Synergy descriptions reference other cards by name — ‘deal damage equal to the number of [Wound] cards in your discard pile’ requires the translated name of Wound to be used consistently everywhere it appears. SandVox’s terminology management system tracks every card name, keyword, and mechanic as a registered term. When that term appears anywhere in the translation — in a card description, a tooltip, a run summary — the exact registered translation is used. Post-translation, a consistency QA pass specifically checks for all term references to verify consistency.
