For first-time prop bettors who want to know why a bet is worth it, not just whether to tail it.
ET Parlays (The Lab) is a sports-betting research tool for newer bettors. It grades player props with the reasoning shown and checks your bet slip leg by leg before you place it. You bet wherever you already bet; ET is the Lab.
The Tool
Every prop. Graded. Explained.
Not just a pick: you see the tier (S/A/B/C), the stats behind it, and exactly why it's a play.
The Method
Three principles. One lab.
We don't tweak the model when the slate has a bad night. The doctrine is the product.
01
Tier grades, not tip sheets.
Every prop scored S/A/B/C from the model. You see the math. A B stays a B; we don't repackage it with marketing copy.
02
Trust and verify.
A ranked board if you want a fast read. A sortable Board if you want to scan the slate yourself. Both, every day.
03
Bring your own book.
Slip Check runs any slip against the ET database, so you see exactly how each player grades on today's slate. Book-agnostic by design: bet where you want, check the read here first.
Coverage
Six leagues. Done right.
We don't pad the marketing with sports we haven't built yet. What's listed is what's live.
MLB
Full slate, every prop tiered. Read against the matchup before first pitch.
NBA
Same depth as MLB. Every prop tiered, every matchup read before tip-off.
WNBA
Full slate coverage with the same grading depth as NBA. Tiered props on every game.
WTAATP
Tennis
Grand Slams with serve-model predictions and same-match correlation surface, the only tool modeling joint leg outcomes.
World Baseball
KBO + NPB. Props nowhere else will touch. Built for the gaps when domestic markets sleep.
NFL
Kickoff Sep '26
Already built: model, Top 10, Player Lab. Waiting on kickoff to unlock for everyone, Week 1 Sep '26.
Football
Next up
EPL, La Liga, and the Champions League are what's being built next. No date until it's actually live.
What's Inside
Seven tools. One opponent.
How It Works
Research to receipt in minutes.
01
Pick your sport
MLB, NBA, WNBA, Tennis, or World Baseball (KBO · NPB). Every game on today's slate is loaded with the full prop breakdown and tier grades. NFL is built and waiting for kickoff, Sep '26.
02
Find your edge
Every prop is tiered S through C. S-tier marks the model's highest-confidence calls, where the data alignment is cleanest. Tap any stat chip to see what's driving it.
03
Build and check
Add legs to the parlay builder, or paste a slip from any sportsbook into Slip Check. See how each leg grades against today's slate before you lock it in.

ET Parlays is the Lab, not a sportsbook. We don't take bets or sell picks — we help you price them. If you tap through to a book, we may earn a referral fee (Terms §5); it never changes a grade.
Common questions
Do I bet through ET?
No. ET never takes a bet. You wager at your own sportsbook, right where you already do. ET is the Lab: it grades the board and checks your slip before you place it.
Is this legal?
Yes. ET is a sports-analytics tool, not a sportsbook. It's research and education. You place your own bets at licensed books, where betting is legal.
Will books limit me for using it?
You're reading data, not running bots or arbitrage spam. We can't speak to every book's terms, but using research to make your own bets is as normal as checking a box score.
What if I can't read odds yet?
That's exactly who ET is built for. Every grade shows the reasoning, and the Lab Guide teaches de-vig, implied probability, and the rest as you go.
Are you paid by sportsbooks?
Never for a grade. Memberships fund the Lab, and we may also earn a referral fee if you tap through to a book and sign up there — that's spelled out in Terms §5. What no book can buy: a grade, a ranking, or a spot on the board. Price Check shows the best number wherever it is, partner or not, and a bad line gets called a bad line.
Can I cancel?
Anytime, in two clicks — either plan. Annual plans also carry a 30-day, no-forms money-back guarantee: a full refund inside your first 30 days, no questions asked.

Honestly, I'm pretty new to sports betting and usually all the numbers and data confuse the hell out of me. But ET Parlays actually breaks down the player and game odds in a way that makes sense. It just gives you good info so you aren't blindly throwing your money away.
