Let's get the disclosure out of the way: we build Felt Trainer, so grade this page accordingly. And let's get the concession out of the way too - Wizard of Odds is still the best casino math reference on the internet. We check our own numbers against it. If what you want is an encyclopedia, you already found it.
But an encyclopedia is a specific kind of tool. Wizard of Odds teaches the way a textbook does: tables of edges, essays on strategy, practice games off to the side. That works if you enjoy the math for its own sake. It works less well if what you actually have is a trip in three weeks and a game you've never played. Reading about the Pass Line and standing at a table making the bet are different skills - and the second one is the one the casino tests.
Read Wizard of Odds when you want to know. Use Felt Trainer when you want to rehearse. Felt Trainer is a free, no-signup practice table for craps, blackjack, roulette, baccarat, and three poker-based games, with a coach that flags the smart play on every single turn and tutorials that walk you through your first hands. The house edges shown are computed from the same engine you're playing on, so the numbers can't drift from the game.
| Wizard of Odds | Felt Trainer | |
|---|---|---|
| What it fundamentally is | A math reference with practice games | A practice table with the math attached |
| Cost / signup | Free, no signup | Free, no signup |
| Depth of odds analysis | Unmatched - decades of it | Core bets for every game, engine-verified |
| Real-time coaching | On some games (blackjack, video poker, UTH) | Every game, every bet, with the why |
| Guided first-timer tutorials | Article-based | Yes, in-game, step by step |
| Trip prep (etiquette, tipping, hand signals) | Limited | Built for it |
| Multiplayer practice | No | Craps, with friends |
| Interface | Functional, dated | Modern, phone-friendly |
| Advantage-play depth (card counting, etc.) | Extensive | Not our lane |
Both sites are free with no account required. Comparison reflects the sites as of July 2026.
You want rule-variant analysis ("what does H17 cost me at a 6-deck table?"), advantage-play theory, or the edge on some obscure side bet a casino just invented. That's what it's for, and nothing else comes close. Plenty of people should have both tabs open: theirs for the reference, ours for the reps.
The trip is booked and the goal is confidence, not scholarship. You'd rather make fifty practice bets with a coach correcting you than read fifty paragraphs and hope it sticks. Or a craps table is the specific thing that intimidates you - our first-table walkthrough rehearses the parts no odds table covers: the dealer's calls, where your hands go, when you're allowed to act.
No signup, no download, no real money. Just reps.
Felt Trainer is a free, no-signup alternative focused on practice: playable craps, blackjack, roulette, baccarat, and poker trainers with a real-time coach that explains every bet as you make it. Wizard of Odds remains the deepest free reference for the underlying math.
Yes. For raw casino math - house edges, rule variations, strategy analysis - Wizard of Odds is still the most complete free resource anywhere. The common complaints are the dated interface and the encyclopedia-style teaching, not the accuracy.
Wizard of Odds is a reference you read, with practice games attached. Felt Trainer is a practice table you play, with the math attached: a coach flags the smart play on every turn, guided tutorials walk you through your first hands, and the house edges are computed from the same engine you play on.
