Beginner PV, Google Play, and HoloJan Visual
Beginner Assist Helps Players Read the Table
The new PV is aimed directly at people who may be interested because of Hololive but have little experience with mahjong.
Beginner Assist can display possible yaku and recommend a tile to discard. After a match, the game-record function also lets players revisit their decisions and review how the hand developed.
Talent Interaction Goes Beyond Mahjong Matches
HoloJan is built around the idea of playing with an oshi. Newly recorded voices and match stamps are joined by Situation Scenarios unlocked through playing with talents.
Affection is also tied to Character Stories. Matches, gifts, and the talk function provide additional ways to deepen the relationship with a selected talent.
Four Modes Cover Solo, Friends, and Online Play
Four major match options have been announced. Ranked Match and Tournament focus on online competition, while Single Mode lets players proceed at their own pace.
Friend Match provides a separate option for playing directly with friends without always entering ranked competition.
37 Talents and Oshi-Themed Customization
A total of 37 talents are currently scheduled to participate, spanning early Hololive generations through holoX, ReGLOSS, and FLOW GLOW.
Players can also customize match presentation around their favorite talent, including riichi animations, sticks, tiles, tables, and frames.
Why This Matters
1) Newcomers are a core audience
Beginner Assist means people drawn in by Hololive do not need to arrive with established mahjong knowledge.
2) Talent progression exists outside the match itself
Stories, affection, gifts, and talk give players progression beyond simply winning or losing.
3) Customization reinforces the oshi-focused concept
Multiple parts of the table and match presentation can be themed around the chosen talent.
