Revision history: 50/50

The 50/50 is the featured-character guarantee structure popularized by Genshin Impact and now standard across HoYoverse games and their competitors. When a player pulls a top-rarity character without an active guarantee, there is a 50% chance it is the banner's featured character. If it is not (the player "loses the 50/50" and gets an off-banner character from the standard pool), the next top-rarity result is guaranteed to be the featured one. [1]

Combined with hard pity at 90, the structure gives a clean worst case: 180 pulls always secures the featured character. This bounded arithmetic, more than the base rate, is what players budget around, and phrases like "I'm guaranteed" (a banked 50/50 loss) are core community vocabulary.

Variations on the coin flip:

• Genshin Impact's Capturing Radiance (Version 5.0, August 2024) softens losses: HoYoverse publishes a 55% consolidated featured share, with an automatic conversion after three consecutive losses. [2]
• Weapon banners typically run 75/25 with the same loss-guarantee structure (Honkai: Star Rail, Zenless Zone Zero).
• Wuthering Waves removes the flip entirely on its weapon banner: every 5-star there is the featured weapon.
• Older designs like Fate/Grand Order have no flip and no loss protection at all; the featured share is just a fractional rate-up.

Whether a lost 50/50 still feels worthwhile depends on the standard pool's quality, which is one reason standard-pool powercreep is watched closely by players.
