Free Embeddable Casino Calculators
Four small tools you can drop into a blog post, a trip-planning page, or a forum wiki with one iframe tag. No signup, no key, no cost. Each one runs on the same engines as the Felt Trainer practice tables, so the house edges it shows are the ones the trainers actually use.
How to embed one
Copy the tag under the widget you want and paste it wherever your page accepts HTML. The width is fluid; change the max-width to fit your column and leave the height alone unless the widget gets cut off. Each frame keeps a small "Felt Trainer" credit at the bottom that links back here. That credit is the whole price, and the reason we can keep the tools free.
What you get, and what you don't
- Accurate math. The widgets import the engines directly. When a rule or payout changes in the trainer, the widget changes with it, and the test suite checks that the two agree. Details in how we compute house edge.
- No ads, no cookies. Nothing in the frame sells anything or tracks your readers beyond a cookieless pageview count.
- No real-money links. The widgets never link to a gambling operator, so they are safe on pages that need to stay clear of gambling promotion.
- Fixed colors. The frame looks the same on every host. If that clashes with your design, tell us through the feedback button and what you're building; a themed variant is on the list if enough people ask.
Calculators, a what-to-play picker, printable cheat sheets, and a table-rule comparison, all free.
Frequently Asked Questions
Are the Felt Trainer widgets free to embed?
Yes. Copy the iframe tag and paste it in. No signup, no API key, no cost. Leave the small Felt Trainer credit inside the widget in place; that's the deal.
Where do the numbers come from?
The same open game engines that run the practice tables. Every house edge is computed from the engine's payout rules and cross-checked by automated tests, so a widget can't disagree with the trainer or the payout charts.
Do the widgets set cookies or track visitors?
No cookies, no fingerprinting, no ads. Each frame loads a small page from felttrainer.com and records a cookieless pageview with Plausible. Nothing goes to third parties.
Can I change the size or colors?
Size, yes: edit the width, height, or max-width in the tag. Colors are fixed so the tool reads the same everywhere. Ask through the feedback button if you need a themed version.
