Made by players for players

We started not with a platform, but with a question: how do these games really work? We built tools that we could trust, tested them live, and prove they work.That’s how 101RTP started — built to give every player the same advantage.

Our vision & mission

Our vision

To give players the knowledge and tools to play with the same insight the house uses.

Our mission

We began by studying the games ourselves. Now we help players see the full picture.

101RTP: from idea to MVP

How a group of players turned curiosity into a real advantage.

December 2015

It began with roulette bonuses — tested through Monte Carlo simulations, only for personal use.

February 2017

After one casino unfairly took a $12,000 win, we realised players needed someone on their side.

October 2020

We analysed our first slot, Twin Spin by NetEnt, to study multipliers and tournament behaviour.

December 2020

The team grew: we added our first member dedicated to bonus value analytics.

2021

We moved into backend development — building a stable system for data collection and storage.

January 2021

We entered a new phase — jackpot tracking began on 27 January 2021. Since then, we've monitored over 1,000 jackpots across hundreds of sites, analysing licences and breakeven points.

July 2021

We registered the 101RTP domain on 26 July 2021. We call it our unofficial birthday.

2022

We created a private interface to test tools internally before release.

2024

We launched the public version with $1.3M investment — showing clear results and earning player trust.

April 2025

The current 101RTP platform launched in April 2025. It lets players track Max Win probability, EV, and slot potential for smarter play.

I write about what actually matters — slots, betting, and casino mechanics. In my downtime, I'm either deep in video games, reading everything from fantasy to poker non-fiction, or planning my next trip to some ancient ruins. Maybe it will be a temple in Cambodia or an amphitheatre in Greece? Who knows.View all articles

How we’re different

Built not from theory, but from years of real play and results.

Insights casinos won’t
share

We show the numbers casinos keep quiet about — so you can play with full clarity.

We speak your
language

We’ve been there: сhasing bonuses, spotting fakes, learning from real play. The tools we built for ourselves are now yours.

Tips from
winners

We’ve played, tested, and won. Everything here comes from real results — not talk.

FAQs

What is 101RTP and what does your team do?

We’re players who built mathematical tools for ourselves, which have generated over €1 million in profit. Now we share everything with the Irish gambling community.

Are your online casino reviews independent and unbiased?

Absolutely. We rank casinos based on 8 main and 30+ additional verified parameters.

How does 101RTP test and rate casino sites?

We play with real money, test actual withdrawals, verify RTP through statistical analysis, and stress-test support. We go through the whole process and document what happens during every stage.

Do you work with licensed and legal online casinos only?

Yes. We only recommend casinos licensed by reputable jurisdictions like Malta, Curacao, or the UK that accept Irish players legally.

How do you make sure a casino is safe and trustworthy?

We test withdrawal speeds with real money, analyse bonus terms, and monitor player complaints. If we wouldn’t trust a casino with our own bankroll, we don’t recommend it.

Do you get paid for casino reviews or rankings?

We earn affiliate commissions when you sign up through our links, but we don’t accept payment to adjust rankings. Our reputation as players matters more than any partnership deal.

What does 'RTP' mean and why is it important for players?

RTP is the percentage a slot pays back over time. For example, 97% RTP means €97 returned for every €100 wagered long-term. Higher RTP means better odds.

How do you verify payout speed and withdrawal policies?

We make real withdrawals ourselves. Our team members set different amounts and different payment methods. We document processing times, not what’s written in the terms.

Do you test casino bonuses before recommending them?

Yes. We run millions of simulations through our Bonus Value engine to determine actual Expected Value and ROI.

How can I contact the 101RTP team?

Use the email provided on our site or reach out through our social media channels. We’re players who help players. So, if you’ve got a legitimate question, we’ll answer.
