Slots of the month featured on casino home pages

What we consider "presence on the main"

We take into account only the first screen (desktop/mobile) and the "quasi-first" when auto-scrolling:
  • Hero banners (H1/H2/H3).
  • Top Ribbon/Featured Strip (first 6-8 tiles).
  • Featured Grid: line 1 (up to 8 tiles) and line 2, columns 1-4 on mobile.
  • Below - is not considered "main." Positions receive weights (see PosW).

Period and coverage

Period: current calendar month (AU).

Coverage: operators/skins aggregated by unique backends; duplicates of "white labels" are consolidated.

Traffic shares: the weight of the casino is proportional to AU traffic (mobile/desktop - 70/30).

Anti-cheating and data cleaning

We note PromoFlag: paid pins, exclusives, sponsorship rotations.

We exclude "event" banners without a direct click in the slot (reg lands, tournament lands).

Dedup by titles/series (Mega/Megaways/XL versions) - count game families.

AU slice: locale, currency, timezone; bots/internal viewings - out.

Key metrics

Exposure:
  • SOV\_ home (Share of Voice,%): the share of AU traffic where the title was present on the main ≥1 day of the month (weighted by casino traffic and device).
  • Time\_ on\_ home (% days): fraction of days of the month when the title was "on main."
PosW (Position Weight, 0-1): average position weight:
  • H1=1. 00, H2=0. 85, H3=0. 70, TopRibbon 1–4=0. 65, 5–8=0. 55, Grid R1=0. 50, Grid R2 C1–4=0. 40.
Post-click behavior:
  • CTR\_ home→game (%): Clicks from the main slot lobby.
  • F2S (First-to-Spin,%): the proportion of transitions who made ≥1 spin.
  • MSL\_ home (min): The median session time of traffic from the master.
  • RR7\_ home (%): return to title in 7 days from the "home" audience.
  • Decay (κ): CTR/F2S drop rate by rotation days (exposure stability).
Risk and quality control:
  • σ\_ loss100 (bet ×): variance of net result per 100 spins in the "home" audience.
  • HR/BEF/CBC: base frequencies (hit rate, bonus entry, "price" of natural input) - to separate "beautiful banners" from real mathematics.

Composite indices

1) Main presence index (HPI, 0-100):
  • HPI = 0. 40·SOV\_home + 0. 25·PosW + 0. 20·Time\_on\_home + 0. 10·CTR\_home→game + 0. 05·(1−PromoShare)
  • where PromoShare is the share of promo pins in the total exposure (we fine for the "purchased" showcase).
2) Post-click engagement (PCE, 0-100):
  • PCE = 0. 35·F2S + 0. 25·MSL\_home + 0. 20·RR7\_home + 0. 10·(−Decay) + 0. 10·BS
  • where BS is the "bankroll smoothness" (invert σ\_ loss100).

TOP threshold: HPI ≥ 65 and PCE ≥ 60 for at least 14 consecutive days per month.

Why do these slots end up on the main

New releases with understandable features (Hold & Win, cascades + multi).

Evergreens with high conversion from main (stable F2S).

Seasonal themes (Egypt/Asia/Ireland/Outback) under campaigns.

VIP-oriented (high cap, managed variance).

The casino leaves the title in the first screen if the CTR/F2S does not "pour" and there are no complaints.

Archetypes of the "main" and their profiles

1. Hero hit: H1/H2 with high SOV\_ home; need F2S ≥ 55%, Decay low.

2. TopRibbon-aquisitor: cheap rate, frequent mini-events; draws a new audience.

3. Evergreen: average volatility, stable at MSL\_ home and RR7\_ home.

4. High-roller showcase: high cap, buy-centric; show dosed (control σ\_ loss100).

5. Theme campaign: Outback/season/brand collab; good CTR but keeping an eye on Decay.

Section Display Checklist (Editorial)

Title card in "Hottest Pokies of the Month":
  • HPI (percentile of the month) and PCE.
  • SOV\_ home/PosW/Time\_ on\_ home/CTR/ F2S/Decay - short tags.
  • PromoFlag: "yes/no," PromoShare (%).
  • Mechanics profile: H & W/cascades/cluster/mega; HR/BEF/CBC.
  • Recomend. bankroll (× rates) and volatility (icon).
  • Why on the main: 2-3 factors (conversion, topic, campaign).
  • Mobile note: Checkup crop banner/tile (important for AU-mobile).

Section filters: mechanics, Promo = off, bet, mobile/desktop, VIP focus. Sort by HPI (default) or PCE.

Quick Player Recommendations (AU)

If you want short sessions: look for cards with F2S ≥ 55%, MSL\_ home 6-10 minutes, moderate volatility.

If the "movement" and feature are important: see BEF ≥ medians, CBC ≤ medians, Decay low (slot "does not burn out" in 2-3 days).

Risk sensitive: Avoid high σ titles\_ loss100 and PromoShare> 50% (often "flash" without hold).

Jackpot hunter: choose titles with an honest buy≤CBC and a smooth base mark - otherwise you will get tired to feature.

The practice of rotations (how casinos keep the "main" effective)

Test window 72 hours: if CTR↓> 30% and F2S↓> 20%, the slot goes below the fold.

A/B creatives: at least 2 banner options (mobile crop is required).

Dedup rule: no more than 1 slot of one family in the first screen.

Genre quotas: 40% - new items, 40% - evergreens, 20% - campaigns/VIP.

Typical distortions and how to extinguish them

Purchased showcase: penalty through (1 − PromoShare) in HPI.

One-day bursts: 14 days of stability required.

Duplicate skins: combine into one backend.

"Beautiful banner," empty math: PCE cuts false start.

Desktop only: AU mobile dominates → 70% weight.

Mini-glossary

SOV\_ home is the proportion of AU traffic where the slot was on the main.

PosW: weighted average weight of the position (Hero> Ribbon> Grid).

F2S: "click from home → first spin" conversion.

MSL\_ home: median session time for the "home" audience.

Decay: Reduce metrics in rotation (lower is better).

HPI/PCE: exposure and engagement indices after click.

Conclusion

Top "Slots of the Month on the Main" is not a list of banners, but the intersection of two planes:

1. HPI: the real share and quality of presence on the first screen at the AU casino.

2. PCE: what happens after clicking (F2S, MSL\_ home, RR7\_ home, Decay).

Only titles that are visible and hold - fall into the "Hottest Pokies of the Month (AU)" without marketing noise.
