What do you mean "first places"
We fix positions on the main/in the section and in the "top/popular" lists for the last 7 days (sliding) window, with segmentation:
We take into account only active versions of the game (without takes of "skins").
Base Metrics (Ranking Core)
Launch CR = First Spin/Card Views. Target: ≥ 38-50%.
ASL (min/session) and SPS (spin/session): not lower than median section.
HR (Hit Rate): 28-40% is the rhythm of the base game.
BER (bonuses/100 spins) or MFR (mini-events/100 spins): event every 8-25 spins or bonus ≈ 1/85-1/140.
Fav/Add (favorites/100 unique): ≥ 10-15%.
Reopen: ≥ 30-45%.
PW100 (profitable backs ≥1×/100) or NPS (share of sessions with a total ≥ start): PW100 ≥ 10/NPS ≥ 30%.
TTI (web, before the first spin): ≤ 4-6 s.
Crash/Error Rate: ≤ 0.5% of sessions.
Scoring (final score for the top)
We normalize the metrics by the percentiles of the week, "cut off the tails" (winsorize 1-2%).
Penalties (up to − 15%): Crash/Error, abnormal traffic from one source, long "quiet" series (DSR), duplicates of "skins."
First Place Tolerance Threshold
A game falls into the pool of candidates if at the same time:
Mechanics more likely to go to the top
Hold & Win/Re-Spin - short cycle "target → respin → good," high SPS, strong Fav/Add.
Cluster/Tumble with progress multipliers - "live" base, high ASL, even Reopen.
Megaways + random modifiers - setup variability, high launch CR.
Light Free Spins (light FS + Retryggers) - an affordable bonus, stable interest of new players.
Sticky/Walking Wilds - series of 2-4 spins, "hope effect," the growth of Reopen.
Collect & Fill (collection/meters) - visible progress, increased replayability.
Technical requirements for holding the top (web)
HTML5/WebGL, the weight of the first screen ≤ 5-8 MB, lazy downloads.
TTI ≤ 4-6 s, re-entry ≤ 2 s, stable 50-60 FPS.
Skip animations, large CTA (≥ 44 px), ≥ 16: 9/19. 5:9/4:3.
Correct return from the background, resistance to changing orientation/network.
Zero critical errors per 1000 + test sessions.
Balance of the "first places" list
Provider quota: no more than 2 positions from one studio.
Release age: at least 30% - new items (≤ 45 days), at least 30% - evergreens (≥ 6 months).
Variety of mechanics: Respin, Cluster/Tumble, Megaways, Light FS, Sticky/Collect.
Anti-manipulation: eliminate bursts from a single channel/geo not replicated for 48 hours.

Pre-publication checklist
1. Normalize metrics (percentiles D − 6... D0), remove duplicate versions.
Operational routine
Updated weekly at a fixed time (for example, Mon 00:00).
Monitoring: emergency recalculation at Crash> threshold or abnormal traffic.
Stability control: tolerance of account fluctuations ± 15% WoW; more - audit.
Removal from the top: two reports in a row, scoring drop> 15% or violation of Crash/TTI thresholds.
Red flags (do not let up)
TTI> 7-8 s, start "weight"> 10-12 MB, microfreezes on mobile.
HR <26%, long silent series> 40 spins without mini-events.
Fav/Add <8%, Reopen <30% in the valid sample.
Obsessive Buy Feature as the main gameplay in the base.
Traffic anomalies not confirmed by repetition after 48 hours.
Responsibly
The first places in the catalog are not equal to the guarantee of winnings. Recommend time/bank limits, breaks, sober risk assessment. Play only licensed projects in your region.
Bottom line: the catalog leaders are slots with a quick start, a "live" base (events every 8-25 spins), understandable progression and pure UX, confirmed by CR, ASL/SPS, BER/MFR, Fav/Add, Reopen, PW100/NPS. Keep strict tolerances, transparent scoring and balance by mechanics/providers - so the "first places" will really reflect the choice of players, and not a marketing showcase.

First Place Tolerance Threshold
A game falls into the pool of candidates if at the same time:

- (BER normal or MFR ≥ "event every 8-25 spins"),
- Fav/Add ≥ 10%, Reopen ≥ 30%,

💡Extremely high volatility without compensating MFR/random mods less often holds the first positions: CR, Fav/Add and Reopen fall.
