Made by players for players

We, a team of players, started calculating roulette bonuses using Monte Carlo simulations – purely for personal use.

A reputable online casino unfairly confiscated a $12,000 win, clearly showing the need for an honest, independent resource for players — this happened on 14 February 2017.

The team had parsed its first slot — Twin Spin by NetEnt — to analyse multiplier frequencies and gain a competitive edge in tournaments. This took place on 11 October 2020.

We hired our first team member to work on bonus value calculations.

We shifted focus on backend development to create a robust system for collecting, processing, and storing data.

The project entered a new phase with the start of jackpot tracking on 27 January 2021. From that point on, the team monitored over 1,000 jackpots across hundreds of websites worldwide, covering a wide range of gambling licences, and calculated breakeven points.

The domain 101RTP was acquired on 26 July 2021 — a milestone now considered the project's unofficial birthday.

A fully functional internal frontend built for private use.

The platform launched publicly, accompanied by $1.3 million in investment. We proved our value — and earned trust.

The MVP launched — the platform you're using today. Players can now objectively assess Max Win chances, calculate EV, and identify high-potential slots for smarter play.
