Weekly Ranking Report — 2026-W31

The South Korea App Store Top Grossing chart saw significant movement during week 2026-W31. A total of 82 games experienced ranking changes, with 15 new entries breaking into the chart and 15 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 젠레스 존 제로 - 주년 기념 by COGNOSPHERE PTE. LTD., which surged 88 positions from #89 to #1 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, 메이플스토리M experienced the largest decline, falling 40 spots from #59 to #99. 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 젠레스 존 제로 - 주년 기념 (#1), WOS: 화이트아웃 서바이벌 (#2), and 운빨존많겜 (#3). 젠레스 존 제로 - 주년 기념 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 열혈강호: 넥스트 (entering at #6), 이환 (entering at #27), 몬길: STAR DIVE (entering at #40). 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.
