How to Check RTP Yourself: 5 Simple Steps

The 5-Step Method We Use on Every Slot We Test

This is the exact process we follow. It takes about 2 minutes per slot. No tools required - just the game itself and a published RTP source to compare against.

01

Open the game in real-money mode at the casino

This is important. Demo mode sometimes shows different RTP figures - or the same figure regardless of what the casino has configured. Always check from a logged-in real-money session. The RTP shown in that mode is the one the game engine is actually set to deliver at that casino.

✕ Don't use demo mode - it may not reflect the casino's configured variant

02

Find the game info, rules, or paytable screen

Every certified slot must display its RTP somewhere accessible to the player. Look for a button labelled Info, Rules, Paytable, ?, or the three-bar menu icon. It's usually in the top corner of the game frame. On mobile it may be behind a settings icon.

ⓘ Location varies by provider - see the provider guide below if you can't find it

03

Find the RTP figure - note the exact decimal

The RTP is typically listed near the bottom of the game info screen, sometimes labelled "Return to Player" or "Theoretical RTP". Write down the full figure including decimals - 94.25%, not "about 94%". A 2pp gap is easy to miss if you're rounding. Some slots show a range (e.g. 92.37%-96.26%) - the figure in brackets or listed as "current" is the configured variant.

✓ Note the exact decimal - small gaps cost real money over a session

04

Look up the provider's published maximum RTP

The provider publishes the maximum certified RTP for each slot - usually on their website, in their game library, or in trade press coverage. Our database lists the published max alongside what we recorded at each casino. The difference between these two numbers is the gap the casino has introduced by choosing a lower variant.

ⓘ Use our database to skip this step - we've already looked up the max for each slot we've tested

05

Calculate the gap and decide whether to play

Subtract the in-game RTP from the published max. A 0pp gap means the casino is running the best available variant - as good as it gets. A 1-2pp gap is common and acceptable. Anything above 3pp is a meaningful difference - equivalent to hundreds of dollars in extra expected cost over a long session. Use the gap evaluator below to put a dollar figure on it.

✓ 0pp = max variant, 1-2pp = acceptable, 3pp+ = significant cost

If the RTP isn't shown at all: That's a red flag on its own. Licensed casinos operating under MGA or UKGC rules are required to display RTP to players. A missing figure either means it's buried very deep in the rules, or the casino is operating with less oversight. Either way - note it and factor it in. We log hidden RTPs separately in our database.

Where to Find RTP by Provider - It's Not Always Obvious

Each provider puts the RTP in a slightly different place. Here's where to look for the providers in our database.

Hacksaw Gaming

Info button › Game Rules tab

Listed as "RTP" near the top of the rules section. Shows range if multiple variants exist - the lower figure is the current configuration.

Pragmatic Play

≡ menu › Game Rules

Listed as "Return to Player" toward the bottom of the rules page. Single figure shown - that's the configured variant.

Play'n GO

Info icon › Paytable › last page

Navigate to the last page of the paytable. RTP is shown as a percentage - sometimes a range with the current figure noted.

BGaming

Info button › Game Info tab

Listed under "RTP" in the game info panel. Single figure - the configured variant for this casino.

Yggdrasil

? icon › Info section

RTP shown in the general game information section, usually listed as a percentage range with the current variant indicated.

Wazdan

Info › Game Rules

Listed in the game rules section. Wazdan slots offer a volatility level picker in-game - RTP may vary slightly by volatility setting.

Spinomenal

≡ menu › Paytable

Scroll to the end of the paytable. RTP shown as a single figure.

OnlyPlay

Info button › Rules

Listed in the rules section under "RTP". OnlyPlay typically runs mid-to-high variants - we've recorded what we found at each casino.

General rule: If you open the paytable and don't see an RTP on the first screen, scroll to the last page of the rules section. Almost every provider puts it there. If you still can't find it after 2 minutes, treat it as a hidden RTP and note it as such.

Gap Evaluator - What the RTP Difference Costs You

Enter the in-game RTP you found, the provider's published maximum, and your typical session details. The evaluator shows the expected extra cost of the gap over your session.

The Le Zeus example above uses our real Pistolo reading (92.37%) against the certified maximum (96.26%). Over 500 spins at $1/spin, that 3.89pp gap costs an extra $19.45 in expected losses - on top of what the casino would already take at the max variant. Over a monthly session that compounds significantly.

Pre-Spin Checklist - Tick These Before You Bet

Use this before starting any session. Click each item to check it off.

I checked the in-game RTP from a real-money session - not demo mode and not from a review site quoting the published max.

I looked up the provider's published maximum and know the gap between that and what this casino is running.

The gap is 2pp or less. If it's above 3pp, I've decided whether that extra expected cost fits my budget.

I've set a session budget and I know roughly what the expected cost is at this RTP for my planned number of spins.

If I have an active bonus, I know the slot contribution rate and have checked whether this slot is eligible. Some bonuses exclude certain providers.

The RTP is actually displayed in the game. If I couldn't find it after a reasonable search, I'm treating it as a hidden figure and factoring that in.

Gap found	What it means	Recommended action
0pp	Casino is running the max certified variant	Best case - play at the best available conditions
0.01-1pp	Minor variance from max - still a good configuration	Acceptable - minor expected cost difference
1-2pp	Casino has chosen a mid-tier variant	Common and acceptable - be aware of the session cost
2-3pp	Noticeably below max - worth considering alternatives	Check if another casino runs a higher variant for this slot
3pp+	Low variant - significantly higher house edge	Weigh the cost carefully - or find a better-configured casino
Hidden	RTP not displayed - less transparency	Treat cautiously - consider playing elsewhere if you care about RTP
