How we analyze this game’s features

Highlight Features

Multiple Expanding Symbols

Multiple Expanding Symbols is an enhanced version of the 'Special Expanding Symbol' feature, a powerful system where, primarily during a free spins bonus, two or more types of regular symbols can simultaneously gain the 'Special Expanding Symbol' ability through retriggers. The core of this feature is to go beyond the limitation of the original method where only one symbol expanded, providing immense potential for multiple types of symbols to cover the screen simultaneously as the round progresses.

Multi-Mode Free Spins

Multi-Mode Free Spins refers to a structure where two or more independent free spins bonus rounds, each with different trigger conditions, internal rules, and potential, exist within a single slot game. This concept is different from 'Selectable Free Spins', where the player 'chooses' one from several menus. Instead, it aims to provide a rich experience, as if multiple different bonus games are hidden within one game.

Bonus Buy Efficiency

Average Bonus Buy Price

This slot's bonus buy price sits within the usual range for comparable slots. Buying the feature can be a reasonable option if your goal is to reach the free-spin round without waiting for a natural trigger. The trade-off is that you skip the base-game spins that would normally happen before the feature, including any wins or volatility from that part of play.

Quality-Degrading

The localization lowers the slot’s overall quality compared with the original-language version, so we recommend a comprehensive review or removal of the localized content.

Below, we share our observations on some of the specific localization issues identified in Book of Aferist.

Select the question-mark icon at the end of each item to read a related case study.

  • The same issues seen broadly across other slots from TrueLab also appear in this game. 
  • Differences in character size between languages were not considered, leaving localized text excessively large or small and reducing readability. 
  • The text assembly script is poorly designed. Word order for subjects, verbs, and objects can differ from English, but the implementation does not account for those differences. 
  • Original-language and translated terms are mixed together. As a rule, each sentence should use one language. Mixing a language without letter case with a Latin-script language that distinguishes uppercase and lowercase makes the entire sentence look noticeably unstable. This inconsistency can also make the product feel unfinished. 
  • Obvious mistranslations, malformed sentences, or inappropriate expressions affect the user’s understanding of the game’s content. 
  • The source-language script contains errors, or some wording has been written in a way that is unsuitable for translation.

This localization assessment is based on the Korean version, but evaluates localization as a whole rather than translation alone.
It focuses particularly on issues likely to occur in other language versions as well.
This assessment is limited to localization and is separate from the overall quality of the slot itself.
