Slot RTP Checker — Live UK Deployed RTP Database

Standard RTP checkers pull a single number from a provider database. That number — the theoretical RTP — represents the maximum return the slot can deliver. It is accurate only if your casino deploys the top configuration.

This RTP checker shows three additional data points for every slot with UK verification data:

UK Best — the highest deployed RTP we have verified at any UKGC-licensed casino. This is the actual return you receive if you play at that specific operator.

UK Worst — the lowest verified deployment. This is the same game, with the same graphics and the same bonus rounds, paying out less per spin because the operator selected a lower tier.

Spread — the gap between best and worst, measured in percentage points. A spread of 5.23pp on Big Bass Bonanza means one casino returns £52.30 more per 10,000 spins at £1 than another. That is the cost of not checking.

Slots with a 0.00pp spread are either fixed-RTP titles (the provider does not offer variable configurations) or titles where we have verified only one UK casino so far. As we add more verified deployments, some zero-spread slots may reveal a gap.

Search by slot name to find a specific game. The results show every UK casino where we have verified the deployed RTP for that title.

Filter by provider to see all slots from a specific studio — useful for understanding provider-level deployment patterns. Pragmatic Play, Play'n GO, and NetEnt all use multi-tier RTP systems. Eyecon and some Hacksaw Gaming titles use fixed RTP.

Filter by casino to see every slot we have verified at a specific operator. This is the fastest way to answer the question: does my casino run top-tier RTP?

Adjust the minimum spread filter to surface only the slots where casino choice creates the biggest cost difference. Setting the minimum to 2.0pp hides titles where the gap is too small to matter.

If a slot you play regularly is not listed, or shows no UK deployment data, you can verify the deployed RTP yourself by opening the game's info panel or paytable at your casino. The deployed RTP is stated at the bottom of the rules section on every UKGC-licensed slot.

An RTP checker shows you the Return to Player percentage for online slots. Most RTP checkers show the provider's theoretical maximum. RTPTrack shows what UK casinos actually deploy — which is often 2-5 percentage points lower.

Our verification process triangulates four sources: in-game info panels at UKGC-licensed casinos, operator help centre and game catalogue pages, certified provider documentation, and corroborating community evidence. Every entry carries a confidence rating (high, medium, low) and a verification date. Read the full methodology on /how-it-works.

The April 2026 Remote Gaming Duty increase from 21% to 40% has begun reshaping UK slot deployments. Operators are passing through approximately 90% of the cost via reduced payouts. Track the latest deployment changes and provider-by-provider impact in our Remote Gaming Duty analysis.
