Weekly Ranking Report — 2026-W42

The South Korea App Store Top Grossing chart saw significant movement during week 2026-W42. A total of 83 games experienced ranking changes, with 12 new entries breaking into the chart and 12 titles dropping out of the tracked positions. The competitive landscape continues to evolve rapidly, reflecting shifts in user acquisition strategies and live-operations events.

The standout performer of the week was 뱅드림! 아워 노트 by BILIBILI HK LIMITED, which surged 42 positions from #88 to #46 in the Top Grossing chart. This dramatic ascent is typically indicative of a major content update, a seasonal promotional event, or a well-executed user acquisition campaign that drove a spike in in-app purchase activity.

On the downside, 세포 특공대 - 전략형 타워 디펜스 experienced the largest decline, falling 22 spots from #71 to #93. Such drops can signal the natural decay following a temporary event boost, increased competition from rival titles, or a shift in user spending patterns. It is important to note that a ranking drop does not always imply absolute revenue decline — other titles may have simply outperformed during this period.

The top three grossing positions are currently held by 로블록스(Roblox) (#1), 메이플 키우기 (#2), and 가십하버: 합성 & 스토리 게임 (#3). 로블록스(Roblox) claimed the #1 spot this week, demonstrating strong revenue performance. The estimated monthly revenue for the #1 position in the South Korea App Store is approximately $8.1M.

Notable new entries this week include 명일방주 (entering at #52), 우마무스메 프리티 더비 (entering at #53), SD건담 지 제네레이션 이터널 (entering at #69). Fresh entries into the Top Grossing chart often indicate successful launch campaigns, viral social media attention, or cross-promotion from established IP franchises. Tracking whether these new entrants sustain their positions in subsequent weeks provides valuable insight into their long-term revenue potential.

The South Korea mobile gaming market remains one of the most competitive segments globally. With 100 titles actively tracked in the Top Grossing chart, the barrier to entry continues to be high for new developers. Consistent monitoring of weekly ranking shifts enables data-driven decisions for user acquisition budgets, content scheduling, and competitive benchmarking.
