Slots by provider.

We rank studios by verified average RTP across their tracked catalog. The current leader is OneTouch at 98.46% average across 5 tracked titles. Individual game RTP still varies inside every studio — check the per-provider page for the top-RTP demos.

The individual game is decisive. A high-RTP studio can still ship a 92% novelty title, and a low-average studio can ship a 97% flagship. The provider average is a useful bonus-clearing heuristic (it tells you which catalog to pick a game from), but the exact game RTP number on the paytable is what actually governs the math.

At licensed operators, yes — testing labs like eCOGRA, iTech Labs and GLI audit the RNG and payout tables for every certified market. The RTP printed in the game info screen is the certified figure. Watch for configurable RTP — some studios ship 92% / 94% / 96% variants of the same title; the operator picks the setting, so the paytable is the source of truth.

Look for high RTP (≥ 96%), medium volatility, and no "excluded" flag in the operator T&Cs. NetEnt, Play'n GO and Nolimit City generally clear this bar; some Pragmatic Play flagships (Sweet Bonanza, Gates of Olympus) can be excluded from wagering contribution — always check the operator's excluded-games list. Full detail in the wagering guide.

We take the arithmetic mean of the certified paytable RTP for every game in the studio's catalog that we've verified — no weighting by popularity. Studios with fewer than five tracked titles are excluded from the hub to avoid outliers. Currently 182 studios and 5 255 games qualify. Refreshed September 2026.

By tracked catalog depth: Pragmatic Play, Play'n GO and NetEnt lead the volume table. Depth matters for player retention (the operator lobby stays fresh) but does not affect long-run EV — a studio with 200 mid-RTP titles is worse for bonus clearing than a boutique with 20 high-RTP titles.
