This Week's Standout Titles

CookieRun: Kingdom
CookieRun: Kingdom🇰🇷 Android

CookieRun: Kingdom jumped +12 after a BTS collab promo and update maintenance extension. Major IP synergy, but without sustained events, the lift may fade.

Arknights: Endfield
Arknights: Endfield🇰🇷 Android

Arknights: Endfield's '탈로스 II의 촬영가' event, running June 5-21, drove a +15 rank rise via community Discord engagement. Event-driven growth, not organic.

少女前線2:追放
少女前線2:追放🇯🇵 Android

Girls' Frontline 2: Exilium rose +12 with 'Radio Wave Addiction' event and a Voymastina collab skin starting June 1. Skin sales likely fueled the spike.

Data Movement Analysis

旦那様の一発逆転人生

旦那様の一発逆転人生's +14 rank climb and +43% revenue surge tie to a 7th-anniversary Senran Kagura collab. Anniversary events often spike, then revert.

Pokémon GO

Pokémon GO's +12 rank rise came from the 'Safari Zone: 인천' live event and Galar Expedition. Live events drive short-term engagement, not retention.

ファイアーエムブレム  ヒーローズ

Fire Emblem Heroes' +14 jump is from a limited 5-day revival banner with 40-summon spark. Short banners create urgency but risk post-event drop.

🇯🇵
🇯🇵jp

JP market: flat revenue, high rank volatility. LINE: Disney Tsum Tsum surged, but concentration on events suggests no organic growth.

🇰🇷
🇰🇷kr

KR market: strategy genre dominates at 35.4% revenue, with 14.2% weekly uptick. Strategy-led growth is stable, but genre concentration is a risk.

What to Watch Next Week

ヘブンバーンズレッド
ヘブンバーンズレッド🇯🇵 #17 · Android

ヘブンバーンズレッド at #17 may drop if no new event launches; its story-driven model relies on frequent updates to retain rank.

Wuthering Waves × Cyberpunk
Wuthering Waves × Cyberpunk🇰🇷 #17 · iOS

Wuthering Waves × Cyberpunk at #17 could see a boost if the collab event expands; cross-IP hype often lifts ranks temporarily.

BrownDust2 - Full Burst RPG
BrownDust2 - Full Burst RPG🇰🇷 #18 · Android

BrownDust2 - Full Burst RPG at #18 might rise if its next event cycle starts; character-driven RPGs often rebound post-event lulls.

Editor's Note

0/5 forecasts hit · Next week: watch if Endfield's event sustains or fades. JP and KR markets may see a correction as event-driven spikes cool. Focus on retention metrics.
