Promosystem is a release radar for online slots: upcoming titles, week-one launches, and a growing archive of everything we’ve already covered. We are an editorial site — not a casino. No accounts, no deposits, no bets on this domain.
What we actually do
- Watch the drop calendar — studios ship constantly; we surface what’s coming and what just went live.
- Open the demo first — if HTML5 loads without a registration wall, we say so; if it doesn’t, we don’t pretend.
- Stick to published numbers — RTP, volatility, max win, buy/ante menus when the provider (or a solid donor) states them.
- Keep old URLs — when a “new” slot ages out of the fresh window, it stays in the catalogue. Permanent pages, changing badges.
What we don’t do
- We don’t run games or hold player funds.
- We don’t invent paytables or “community win” stories.
- We don’t rewrite Slotcatalog casino-bonus grids or geo SlotRank tables into reviews — operator cards on the site are separate.

Maya Okonkwo — Release radar editor

She writes for players who want the fresh drop without the press-release fog: dates, mechanics hooks, and whether the free demo loads clean.
Ethan Caldwell — Games analyst (RTP & math)
Ethan breaks down RTP, volatility, max win, and buy/ante menus when they’re published. Former ops-side iGaming desk; he prefers verified numbers over studio slogans and keeps reviews usable on mobile — short friction notes, no franchise essays.
Priya Nair — Studio & demo correspondent
Priya maps who ships what (Pragmatic, Hacksaw, Push, Nolimit, and the long tail) and checks that HTML5 demos open without a registration wall. Less lore, more “does it run, what’s new this week, and which provider page should you start from.”
