Who does YOSTAR compete with?
The rivals identified
Nemeses(1)
The Mahjong App competes for the same casual strategy gaming audience by providing digital practice for American Mahjong, while Mahjong Soul focuses on Japanese Riichi rules.
Contenders(6)
The legacy benchmark for narrative-driven gacha games; HBR is widely considered its modern spiritual successor in terms of writing depth.
Differentiators
- Deep integration with the broader Sony Music Entertainment ecosystem

Mahjong Friends Online targets the same Riichi Mahjong player base by offering a manual, social-focused alternative to the automated, character-driven experience of Mahjong Soul.
Kemono Mahjong competes by capturing the purist segment of the Riichi Mahjong market that rejects the gacha-heavy, live-service monetization model of Mahjong Soul.
MahJongo competes by offering six distinct Mahjong rule sets, including Riichi, which directly overlaps with the core gameplay of Mahjong Soul.
