Today we're opening zest.win to everyone. After months of building, training and back-testing behind closed doors, the official alpha is live — and to celebrate, anyone who registers before July 31, 2026 gets one month of full access, free. No card, no coupon code. Sign up, verify your email, and everything is unlocked.
What is zest.win?
zest.win is AI-powered match prediction for professional esports. We cover three titles at launch:
- League of Legends
- Counter-Strike 2
- Dota 2
For every professional match on our radar, our models publish win probabilities before the game begins — not just who wins, but the markets that actually matter:
- Series and map winners — including proper three-way handling for Dota 2 best-of-2s, where a 1–1 draw is a real outcome (roughly a third of BO2s end that way) and gets its own probability.
- In-game objectives — first blood, first tower, first dragon and Baron in LoL; first Roshan and race-to-kills markets in Dota 2; pistol rounds and first-to-X rounds in CS2.
- Totals and margins — predicted kill totals, match duration, round totals and margins, early-game gold and XP differentials.
Every prediction comes with a breakdown of what the model sees, and a side-by-side comparison against live bookmaker odds so you can spot where our probabilities and the market disagree.
Probabilities you can actually trust
A prediction service is only as good as its honesty. Two things we committed to from day one:
Calibrated probabilities. When our model says 70%, it should win about 70% of the time. Every model we ship goes through a dedicated calibration step and is monitored for drift — a model that goes stale gets retrained, not left running.
A public track record. Every prediction we publish is graded against the real result and shown on our track record page (/track-record) — per game, per market, across model versions. We don't get to quietly delete the misses. If the models are good, the numbers will show it; if they're not, you'll see that too.
What "alpha" means
We're calling this an alpha because we're honest about where we are:
- Models retrain continuously — expect probabilities and accuracy to keep improving (and occasionally wobble) as new data flows in.
- Some markets are newer than others. Our Dota 2 coverage, including the BO2 draw model, is the freshest addition.
- The UI, coverage and features will evolve quickly. Things may move around.
What you get in return for tolerating rough edges: full access to everything, and a direct line to the people building it. Feedback during the alpha genuinely shapes what we build next.
The alpha offer
Here's the deal, in full:
- Register at https://zest.win any time up to and including July 31, 2026.
- Your account is automatically granted one month of full access — every game, every market, every prediction.
- No payment details required. When your month is up, you decide whether to stick around.
After July 31, new sign-ups won't include the free month — so if you want the full tour on the house, now is the time.
Get started
- Create an account & activate your account — all it takes is an email.
- Check today's matches for live predictions.
- Browse by game, follow your favorite teams and tournaments, and keep an eye on the track record (/track-record) as results settle.
Found something broken, confusing, or missing? Tell us. This is an alpha — you're not just early, you're part of building it.
See you on the winning side.
