Best investment of my life. Almost just from these Charts and the Trainer, I've become a winning player at €5 (maybe even €10, though I also worked on my postflop game, so it should work for you too if you're an MTT player) (edited)
That really is the “dopamine” danger of this Trainer. It's so well made that sometimes I'd rather grind in the Trainer than actually grind.
By the way, I also took a look at the Strategy Guides, and they're really great! Very well put together, they cover all the fundamentals for a solid game. If I'd had this sooner, I would have saved a huge amount of time learning, especially vs fish!

This is excellent: I got caught clicking too fast and made the same mistakes again haha... Then I understood that it was showing me my mistakes, and it really helped reinforce my awareness of the mistake compared with the Chart.
Yes, I understand. I thought about it while writing, and I don't really have visibility on the results or your expectations. From my point of view, you're TOP level for responsiveness/communication/customer service/development, so I see no reason why things shouldn't go in the right direction! I wish you all the best anyway; I promote you whenever I can 😄
Finally! After nearly 8 months of (almost) daily work, I've reached the end of the PF course 🥳 It's funny because when I was playing €2, I told myself, “Once I've finished the PF course, I'll move up to €5 so I'll feel comfortable.” In the end, thanks to you I moved up to €10 well before that ❤️ (edited)
Great work! It's genuinely brilliant to use the Preflop Pack alongside the tracker. Thanks @Madspin for introducing me to it (edited)
Preflop Pack finished. And without help ^^' after forcing myself to work on GTO vs reg... now I just need to keep reviewing until it becomes automatic. It taught me some genuinely EV+ moves vs reg, especially 3-bet bluffs. Since mid-May, when I bought PST and the Preflop Pack, I've moved up to €10 and from early June until today I've clearly taken a step forward and finally settled at that stake. 51 cEV — 9k games. Thanks Mad, Gandalf and Olivier for all your work ;) (edited)
Really cool! Your brain absorbs it very well—it's a kind of instinctive learning that takes shape. Seeing the mistake again immediately and taking another action on it is so good! 👏
make the most of it, it's a gold mine—I wish I'd had this information when I started
amazing to review mistakes directly in the Trainer this is going to make learning so much easier, TOP
Yes, it's very important to repeat and come back to it regularly; that's why the Arena is brilliant, because I work on at least one Chart every day
Hello, just a message to thank you for the site's content. It's really great; I think it's the right balance between thorough, precise content and something that remains very educational.
To illustrate the clear progress since using the Preflop Pack + tracker, here are 4 screenshots from April onward, one per month (I joined PST on April 20, marked by the pink line on the first graph). Clearly I hadn't understood the importance of preflop 😱 (strongly declining redline), so that became the first area for improvement, with the Preflop Pack of course. Results were still nothing special in May (2nd graph), then after putting in some work, you can see things take off around May 20, confirmed in June and July, with cEV shooting up (to be fair, the bar was low! 🥶)... still needs confirming over the long term, of course. There is still a lot to learn and many preflop situations to absorb. It takes a long time to internalize the Charts and identify your biggest leaks (thanks Leak Finder, it's very well made! 👍), but I feel a real desire to keep going and real satisfaction in seeing the work and awareness built with this amazing tool, PST, materialize in the graphs. A huge thank-you to @Gandalf and @Olivier for imagining and creating PST. I wish you all the best for what comes next, because knowing it isn't finished and that you still have many developments in store is really exciting! 🤗
Hey team ✌️ I wanted to take a few minutes to thank you... Honestly, you've created much more than a tool. You've built a real gem of an ecosystem: tracker, explanations, Academy, Leak Finder, Discord... In the end, we almost have no excuses left for playing badly—although I still manage to find some 😁 I'm still clearly a beginner at Spins, but I can feel real progress and honestly, it feels so good... What I especially appreciate is that you don't just throw stats at us and hope we figure them out. You take the time to explain the “why”, and that's what makes all the difference 💪 And I can't forget the two guys I follow religiously on YouTube. You can feel the sincerity, the teaching ability, and above all the passion for sharing. It's genuinely enjoyable to watch 😉 On my side, I have a job that's taking literally all my time right now. Despite that, I still manage to make progress in poker thanks to your tools... thanks to you. Step by step, I'm starting to understand what I'm seeing, why I make certain mistakes, and how to correct them. When I don't have time to play, I can still analyze, learn, and improve. And honestly, it really makes me want to keep going. Another strong point is that with every update, you can feel that you're still trying to improve the product. You're not simply selling software; you're building genuine tools to help players improve. So thank you, sincerely...
I completely agree with everything I've just read. Poker Sciences isn't claiming to offer us a tool that solves Spins as a whole, but rather a tool for calibrating, understanding, exploiting and refining our overall approaches and strategies in Spins. So far, it's mission more than accomplished with the Preflop Pack and the tracker, which genuinely complement each other and are both very advanced in their own right. Combining the two gives you an incredibly high-quality all-round tool that you can find almost nowhere else for the same budget. I'm already licking my chops thinking about what will be built/developed for postflop. (edited)
Everything in one tool.
