How does 100% RTP actually work?
If you fancy playing some 100% RTP Originals at either of these great casinos then it’s important to be aware of how the mechanism actually works. The games themselves have a base 0.1% edge. The game rules don’t change. When you are within your zero edge allowance, all of your bets receive a 0.1% instant rakeback, therefore making your net edge zero.
What is the Daily Allowance?
Both casinos currently have a daily allowance of $50,000. This means that you can play at 100% RTP up to $50,000 in wagers. After this the standard policy is that the o.1% that you got in rakeback no longer applies and you are now playing at 99.9% RTP. Which although not perfect is still so much better than traditional slots! The reason for this is that if a casino allowed you to play unlimited then the variance would be too much and the run the risk of bankruptcy. We must admit that we would like to see these limits raised but as it stands for a new product we think a $50,000 daily limit is pretty generous.
There is a difference however in the stake sizes. Check them out briefly below with a little explainer:
- Gamdom – $50,000 stake limit. Gamdom state that you can win up to $1,000,000 on their 100% RTP games as their limit is very high, perfect for any VIP Gosus! However, if you are wanting to play at these limits then note that one round of Dice with this stake size would use your 100% RTP daily limit.
- Duel – $1,000 stake limit. Duel offer a significantly reduced limit which for the average player is still pretty high. Playing at this level would get you 50 rounds before you use your daily limit – not bad we think.
What is RTP and why is it important?
Casino degens will already know what RTP is but for those Gosus in the early stages of their casino journey RTP is in simple terms the Return-To-Player you can expect. Sometimes this is also called House Edge. What this means is that for every x amount wagered you can expect x% back.
For example, this is what could happen to your Bankroll when playing Wanted Dead or a Wild which has a 96.38% RTP. This means for every $1 wagered you would get $0.96 back. The smaller peaks and troughs are the volatility elements of the game.
IMPORTANT: This is a simulation not the actual way your bankroll will play out.
So 100% RTP, can I win?
The short answer is yes you can. But it is essential you know how it works before you start playing and think you are guaranteed wins. It is true that casinos who operate 100% RTP do not make money through the games themselves because the game has turned into a 50/50. Unlike slots where the casino has a built-in advantage over you, 100% RTP turns it into a neutral game and theoretically completely fair but more on provably fair later. A casino will only make money out of standard variance, not any ingrained advantage.
Take a look at the two graphs below. Both simulate a player betting $1 x 100,000 times.
You can see that in one scenario the player loses and in another the player wins. This is because of the phenomenon known as the Random Walk. It is statistically normal for the results to be anywhere within specific boundaries (up to $2,000$ or more), even in a perfectly fair game. But the key is that you would never lose as much as playing a slot with a baked in house edge. And you have a fair chance at walking away with a winning session.
100% RTP and Provably Fair
For a casino to make a big claim like 100% RTP then it needs more than a “trust me bro”. As any OG Gosus will know we are very big on provably fair technology. Before it was a buzzword we were highlighting its importance and were the first crypto casino guide to have a built-in Provably Fair Checker that is free to use.
Provably Fair technology replaces that trust with mathematics. While RTP tells you the theoretical odds, Provably Fair allows you to verify every single round to ensure the casino didn’t manipulate the outcome. In the crypto world, 100% RTP + Provably Fair is the gold standard because it means the game is both mathematically neutral and impossible to rig. Both the Gamdom and Duel Originals claim to be provably fair and they have passed our test. Some of our players also report that the games work well and do not express any concerns about rigged game or cheating.
