Week 37

The platform shed nearly a tenth of its active islands in a single week, dropping from roughly 51,400 to 46,248 active islands, while the total island count barely moved (up 0.5% to 287,353). That divergence tells you what happened: new publishing held up (4,847 new islands, down only 2.7%), but islands that had been marginal fell below the 5-play activity threshold in large numbers. The active ratio dropped to 15.1%, its lowest point in recent memory and 9.3% below last week. New creator registrations fell 9.7% to 696. This is a consolidation week, not a growth week, and the pruning is concentrated in islands that were never gaining meaningful traction.

The 4.2% rise in average session length to 12.8 minutes is the single most important counter-signal to an otherwise soft week. With total plays down 9.5% but total minutes down only 5.6%, the math confirms that the players who showed up stayed meaningfully longer per session. Average minutes per unique player came in at 39.7. The favorite-to-play ratio jumped 17.7% to 0.0048, while the recommend-to-play ratio fell 23.8% to 0.0028. Players are bookmarking what they like but not actively pushing it to others, which typically reflects a period when audiences are consolidating around familiar favorites rather than discovering new content. The average island drew 1,524 unique players and 85 concurrent players.

Top by Uniques

Two structural patterns dominate the top-uniques and top-growth lists this week. First, the entrenched skill-gaming cluster (BOX PVP, PILLARS, Piece Control 2v2, GO GOATED! Zone Wars) lost 8-13% in unique players each, in line with the platform-wide contraction, but held their ordinal ranks, confirming their floors are deep. Second, a wave of Brainrot variants is fragmenting the trend across more islands: STEAL THE BRAINROT grew 9.7% in uniques and 64.5% in peak CCU, Piece Control 1v1 grew 14.1%, and GROW THE BRAINROT (takuman_kamikz) jumped 76% in peak CCU. The Football Arena [BVB] breakout (204,794 uniques, up from near-zero) is sui generis and almost certainly event-driven. Creators reading these lists should note that the trend is spreading, not peaking, but the individual islands harvesting it are multiplying, which compresses individual share.

D1 / D7 Retention Distribution

0-5% bucket WoW: +7499 islands (D1), +10481 islands (D7) · 90-100% bucket WoW: +216 islands (D1), +100 islands (D7)

The platform-wide D1 retention average rose 0.71 percentage points to 37.3%, and D7 rose 1.17 points to 24.4%, both improvements that run counter to the traffic declines. The bucket distributions show the gains were driven by the middle tiers: the 50-70% and 70-90% D1 buckets each added more than 2,000 islands week-over-week, meaning a meaningful number of islands are building genuine stickiness. At the top of the leaderboard, 1V1 PRO clean (infinitepixel) held the D1 rank at 82.6% and led D7 at 81.9%, a combination that is essentially unmatched on the platform. Star Wars Droid Tycoon and the Brainrot cluster appear in both the D1 and D7 top-10, which means their audiences are not just returning the next day but sustaining the habit across a week. The retention-adjusted engagement (RAE) list is dominated by tycoon islands, with Turbo Ramp Tycoon and Only Up Volcano leading on the D7-adjusted version. If your island drives traffic but does not appear near these lists, your acquisition funnel is working but your loop is not.

Hive leads by unique reach (15.9 million across 12 islands) but ferins leads on every intensity metric: 26.8 million total plays from just 6 islands, a 59.8% average D1 retention, and a peak CCU sum of 772,100 that is more than 8 times hive's 93,695. That gap illustrates the difference between a broad portfolio generating steady volume and a concentrated portfolio generating outsized concurrent demand. Bullseye is the portfolio depth story: 22 islands, 25.5 million total plays, 11.1 million unique players. Outside the top three, rvb dropped 11.9% week-over-week while pandvil fell 10.6%, both sharper declines than the platform average, suggesting their audiences were disproportionately part of this week's drop-off.

THE LADDER (codeseany) held the top average-minutes-per-player position at 845 minutes per unique player, and FREE BUILDING PRACTICE 1V1 (bnstudios) held second at 770 minutes. These are not anomalies of small sample size; they represent islands that have turned Fortnite Creative into a practice tool with near-permanent session durations. The breakout growth lists reveal two separate forces at work this week. Football Arena [BVB] and HARD PARKOUR 0670 DEATHRUN (rodrii, 110,847 uniques, up 20,580%) appear at the top of both unique-player and recommendation growth lists simultaneously, which is the clearest signal of organic viral lift in the data. The session-time growth list is noisier, led by islands with small absolute bases, but TOWER TYCOON (thecampingrusher) growing to 36 minutes per player after a 3,537% increase is a name worth tracking if that number holds next week.

Category Share of Plays

Fastest-Growing Categories

Top Categories by D1

Category Intensity (Plays / Island)

Star Wars holds 37.8% of category-labeled plays (8.2 million), nearly double LEGO in second at 21.9% (4.75 million). KPOP DEMON HUNTERS is the surprise at third with 18.8% share (4.1 million plays). Category intensity, measured as plays per island, tells a different story: KPOP DEMON HUNTERS leads at 2,526 plays per island and LEGO is close at 2,446, while TMNT sits at just 208 despite appearing in the top-8 by total plays. That means TMNT's raw volume is spread thinly across many islands, with most capturing very little. Among genres tagged in the Discover row, Simulation & Tycoon is the standout: 50-minute average sessions, 50.2% weighted D1 retention, 39.1% weighted D7 retention, and a peak CCU sum of 1.14 million. No other genre comes close on any of those three dimensions simultaneously. The opportunity callout this week is Roguelike: the genre has an opportunity score of 91 with an Easy difficulty rating, with a median of 26 days to first row placement and 42% of islands reaching it within a week. The binding constraint is player volume, as row islands run roughly 11.9 times the New-row baseline, so enter with realistic traffic expectations.

Supply vs. Exposure

Epic's genre chart is a separate ranking system from the Discover row genre categories above. All genre-chart totals this week are exact (no estimated figures). Roguelike is the supply-growth story: its island count rose 8.3% week-over-week to 353, the only genre with meaningful supply expansion this week. Every other genre contracted in island count, with Shooter losing 3.9% to 62,270 and Battle Royale down 2.4% to 14,223. Sports & Racing was the one exception outside Roguelike, growing 2.3% to 4,256 islands. On the chart-leadership side: GO UP FOR BRAINROTS (ferins) held the Simulation & Tycoon #1 rank all seven days. VIOLET 2.0 (s2y), Bed Wars (goodgamers), Murder Mystery (goodgamers), and PILLARS (hive) each held the #1 position in their respective genres for the full week with an average rank of exactly 1.0. Jump For Eggs (smuti) leads Survival but was only present for 1 of 7 days, so that ranking should be read cautiously. The largest chart movers were TIKTOK PILLARS! (frozenarctic) climbing 68.9 ranks in Party & Mini Games, and FANTASY DUNGEON (orenzi_cre8t) rising 51.6 ranks in Roguelike. Supply-to-exposure figures for reference: Shooter has 62,270 total islands versus 141 currently in the Discover row; Roguelike has 353 total islands versus 102 in the row; Simulation & Tycoon has 5,413 total islands versus 133 in the row.

The favorite-to-play ratio improved 17.7% this week while the recommend-to-play ratio fell 23.8%, a split that points to a specific behavioral gap: players are saving islands for themselves but not sharing them. The highest fav-per-player ratios this week (Hunt Down the Playerman at 1.8, PARTY DREAM 2.2 at 1.6) exceed 1.0, meaning players are favoriting more than once per play session, which happens when they share an island on a shared account or re-favorite after an update. For the majority of creators, the practical lever is in-session prompting: islands with strong recommend rates this week (SOLO ENDGAME ZONE WARS, LAST CITY: FLOOD ZONE WARS) tend to be competitive formats where the result of a match creates a natural moment to tell a friend. If your genre does not create that moment organically, consider end-of-session summary screens or challenge prompts that make sharing feel like a completion action rather than an ask.

Three things to watch entering Week 38. First, whether the Brainrot trend fragments further as more small islands capture slices of that audience (GROW THE BRAINROT's 76% peak CCU growth and 17.4% D1 improvement are early indicators of a second-tier wave). Second, whether Football Arena [BVB]'s explosive debut holds any volume without whatever drove the initial spike: a collapse would confirm event-dependence, while sustained traffic above 50,000 uniques would signal genuine product-market fit. Third, whether the active-island ratio recovers from 15.1% or continues declining: two consecutive weeks below 15% would indicate a structural supply problem, not just a seasonal one. Session length is the green shoot to protect. If that 12.8-minute average holds or extends while traffic recovers, the ecosystem exits this contraction in better shape than it entered it.
