Primeira Liga 2026/27 Prediction League: a private score predictor for your group
The new Primeira Liga season starts on Friday 7 August 2026. Every fixture is already in trefa.app — 306 matches, 18 clubs, 34 rounds. Set up a private prediction league for your mates, your núcleo or your office, with your own scoring rules and nothing staked.

A Primeira Liga 2026/27 prediction league is a points game where your mates, colleagues or supporters' club predict the exact scores of Portugal's top flight. The season starts on Friday 7 August 2026 and the app keeps the table.
In trefa.app the whole season is already loaded — 306 fixtures across 34 rounds between 18 clubs. It opens on Friday 7 August 2026, when Estoril host Famalicao at 20:15 Portuguese time, and the final round is Sunday 16 May 2027. Nothing is staked and nothing is paid out: no entry fee, no odds, no prize pot, just points and bragging rights. Predict the entire league, or narrow it down to the fixtures of the one club you actually support.
What a Primeira Liga prediction league is — and why it isn't betting
Everyone in a closed group calls the same fixtures, the app compares each prediction with the real result and turns it into points. What makes it different from most of what surrounds Portuguese football online is what is missing: there is no stake, no entry fee, no odds and no prize fund. The app accepts no deposits and pays out no winnings.
It is not a bookmaker: there you play the house for a payout, here you play the people in your group chat for a place in a table. And it is not the office collection where everybody throws in a note and one name comes out of a hat — that is a money game, and it is why plenty of groups quietly avoid organising one.
For a group scattered across several countries — the normal state of a Portuguese supporters' group these days — it also removes the most awkward part: nobody moves money across borders.
How to set up a Primeira Liga prediction league, step by step
It takes a few minutes on a phone or a laptop, and needs no technical knowledge.
- Sign in with Google. On the login page you sign in with your Google account. No password to invent, no registration form.
- Create a league and pick your club. Open create a league. A tree menu walks you through it — choose Football, then Primeira Liga 2026/2027, then optionally tick the club you follow.
- Set the rules and the colours. Configure the scoring the way your group argues it should work, and choose a colour palette.
- Invite people. The app generates a unique invite link and QR code. Drop it in the WhatsApp group, post it to the núcleo's page, or let people scan it in the bar. Whoever clicks, plays.
Do add it to your phone's home screen. Trefa.app is a PWA — you will not find it in the App Store or on Google Play; you save it from the browser with one button and it behaves like a normal app.
What you predict, and how the points work
The core of every league is the exact score. You call 2–1, and how close you land decides what you take: points come from a correct scoreline, from the right goal difference with the wrong scoreline, or simply from picking the right winner.
There is no scoring system handed down from above. As the founder you decide what an exact score is worth, what a correct winner is worth and how a called draw is rated — so two leagues rarely look the same. For a starting point rather than a blank page, the breakdown in scoring rules works identically for a núcleo, a group of friends or an office.
Groups who want more than a scoreline can also switch on predictions for the goalscorer, the assist and the time of the first goal, with the organiser setting the minute brackets. All of it is optional and all of it is scored automatically once the match finishes; the full list is on the features page. Nobody retypes results into a spreadsheet — the table recalculates itself after full time.
Predictions close the moment a match kicks off, so nothing can be changed afterwards and there is no arguing about who called what. The app pushes a reminder before the deadline.
All 18 clubs — or just yours
The 2026/27 line-up in the app is: Academico Viseu, Alverca, Arouca, Benfica, Casa Pia, Estoril, Estrela, Famalicao, FC Porto, Gil Vicente, Guimaraes, Maritimo, Moreirense, Nacional, Rio Ave, Santa Clara, SC Braga and Sporting CP.
This is the feature supporters' groups reach for first. Few people want to invent a scoreline for a Monday-night fixture between two clubs they have no feelings about — if you follow Braga, you want to call Braga games.
Team selection when you create the league lets you tick one club, or several. Everyone then sees only the fixtures your chosen clubs appear in, home and away. Nothing else from the division shows up or gets predicted. So out of 306 fixtures, your list comes down to your club's 34.
You can adjust it later — if three rounds in you decide the rival's games should count too, you add that club in the settings. A club cannot be removed once somebody has predicted one of its fixtures. Tick nothing at setup and you get the full division.
How this plays out across Europe is covered in the supporters' club prediction league for national leagues 2026/27; the English equivalent of this guide is the Premier League 2026/27 prediction league.
Primeira Liga 2026/27 by the numbers
| What | Detail |
|---|---|
| Competition | Primeira Liga 2026/2027 (the Portuguese top flight) |
| Clubs | 18 |
| Fixtures in the app | 306 (whole season) |
| Rounds | 34 |
| First fixture | Fri 7 August 2026, 20:15 local — Estoril v Famalicao |
| Final round | Sun 16 May 2027 |
Opening night of the Primeira Liga 2026/27
| Date | Kick-off (Portugal) | Fixture |
|---|---|---|
| Fri 7 Aug 2026 | 20:15 | Estoril v Famalicao |
The rest of the opening round follows over that weekend and is in the app alongside the opener. One practical note for anyone reading this outside Portugal: kick-off times in the app are shown in Central European Time, one hour ahead of Lisbon in summer, so the Friday opener appears there as 21:15.
For claques, núcleos and supporters' clubs
Portuguese clubs are organised differently from most of Europe, and it matters here. Beyond the club itself there are claques — the organised supporter groups behind the goal — and núcleos, the local branches that carry the club's name in a town, a region or a foreign city. Both are exactly the shape of group this is built for: fixed membership, a shared club, and long gaps between matchdays.
Claques and núcleos. A season-long table keeps a branch talking between matchdays instead of going quiet from Sunday to Saturday, and nobody collects anything from anyone.
Núcleos abroad and Portuguese communities overseas. Members in different countries, time zones and WhatsApp groups all see one fixture list and one leaderboard, and the invite is a single link — no meeting, no paperwork, no transfers.
Cafés, bars and clubhouses. The regulars tap their calls in before kick-off, and by full time it is settled who the resident expert is.
Offices. The Primeira Liga runs from August to May, most of a working year, and a prediction league among colleagues needs no organiser rewriting a table every Monday.
Online communities. Running a club Facebook group, a Discord or a subreddit? A shared table lifts interaction and joining is one tap.
Following your club into Europe as well
Portuguese clubs do not only play the domestic season, and running a second league for European nights means two leaderboards and twice the admin.
The multi-league setting merges several competitions of the same sport into one prediction league: fixtures interleave into a single chronological list and points add up into one table. You pick the competitions at setup and can add more later, and a follow a club across leagues toggle puts your club into every one automatically. How the continental competitions work this season is covered in the European cups 2026/27 prediction league.
Your club's colours
So the league looks like it belongs to your group, the admin can apply a colour palette drawn from real club colours.
The palettes are not named after clubs and this is not official club branding — just visual inspiration. Changing colours touches neither the fixtures, the scoring nor anything already predicted.
When a prediction league isn't the right fit
Worth being straight about the limits. For a one-off call on a single fixture, a season-long table is overkill. If your group's whole point is playing for a cash pot, this is the wrong tool by design — there is no mechanism to take money in or pay it out. And if what you enjoy is transfers and picking a starting XI, that is fantasy football, a different game. What this does well is keep a fixed group engaged across a long season with nothing at stake but pride.

Frequently asked questions
When does the Primeira Liga 2026/27 season start?
The season opens on Friday 7 August 2026, when Estoril host Famalicao at 20:15 Portuguese time. The final round is played on Sunday 16 May 2027.
Is a prediction league the same as betting?
No. There is no stake, no entry fee, no odds and no prize fund — the app accepts no deposits and pays out no winnings. You compete for points and a position in the table, not against a bookmaker.
How much does a Primeira Liga prediction league cost?
A pool of up to five participants costs nothing; from the sixth member onwards it is charged per member. The current terms and prices are on the pricing page. No bets, no deposits, no payouts — you play for points and your place in the standings.
How many Primeira Liga fixtures are ready in the app?
The whole season: 306 fixtures across 34 rounds between 18 clubs. The schedule loads automatically from a sports data feed, so you never type in a fixture, a date or a kick-off time.
Can I predict only my own club's matches?
Yes. Team selection lets you tick one club or several, and only the fixtures they appear in show up — home and away. Out of 306 league fixtures your list shrinks to your club's 34.
In what time zone are kick-offs shown?
Kick-off times inside the app are shown in Central European Time, which is one hour ahead of Portugal in summer. The 20:15 opener in Estoril therefore appears in the app as 21:15.
Can I combine the Primeira Liga with the European competitions?
Yes. The multi-league feature merges several competitions of the same sport into one chronological fixture list and one shared leaderboard, and a toggle follows your club across all of them. There is more in the article on the European cups prediction league.
How many people can play, and can a stranger find our league?
A league works for five friends as well as for a núcleo with dozens of members spread across several countries. It is private and cannot be searched for — you get in only through an invite link or QR code.
