The phrase refers to a tool, generally implemented as a website or application, designed to estimate the likelihood of obtaining specific characters or items in the gacha-based system of the video game Genshin Impact. These tools operate by applying statistical models to the game’s publicly known or datamined gacha rates and pity systems. For instance, an individual seeking a particular five-star character could use such a calculator to approximate the number of in-game currency units, known as Primogems, they would likely need to spend to acquire the character.
The utility of these calculation tools stems from the inherent randomness of gacha mechanics. While the game developers provide base probabilities and guarantee systems (pity), predicting specific outcomes remains challenging. The tools offer users a means to manage their expectations and resources within the game. By providing an estimated cost range, they aid in financial planning for players who choose to spend real-world currency to acquire in-game currency. They also permit players to compare the efficiency of different banner types and strategies. These instruments emerged organically from the player community, reflecting a need for transparency and control within the game’s acquisition system.
