Football World Cup 2026 Prediction Game with Friends (Free, No Betting)

The Football World Cup is traditionally a time when even casual fans turn into experts on tactics, offside traps, and refereeing decisions. The 2026 tournament, jointly hosted by the United States, Mexico, and Canada, will be exceptional in many ways. For the first time, 48 teams will take part, a record 104 matches will be played, and for Czech fans, it carries an extra spark: the Czech national team is returning to the World Cup after twenty long years.

Watching the games is naturally more fun when there is something at stake. That is exactly why private prediction games spring up in pubs, offices, and family group chats. In the past, organising such an activity required a dedicated individual who spent their evenings poring over complicated spreadsheets and chasing people up so they wouldn't forget to submit their predictions. Today, there are much more elegant ways to do it.

World Cup 2026 prediction game with friends: what it actually is

Trefa.app is a Czech app for private sports prediction games for groups of 5–50 people, which is free and does not involve betting real money. It serves as a closed digital space where you can create your own league, invite your mates, and compete together to see who can most accurately predict the outcomes of upcoming matches.

The core idea is to move traditional paper or spreadsheet-based competitions into a modern environment that handles all the admin automatically. The app downloads the latest match schedules itself, collects users' predictions, automatically calculates points after the final whistle, and updates the leaderboard. This means your prediction game with friends practically runs itself with zero maintenance.

Because the system functions as a Progressive Web App (PWA), there is no need to download anything from app stores. You simply add the website to your phone's home screen, and it behaves just like a standard native app, complete with push notifications. These pre-match reminders solve one of the most common issues with similar competitions.

"We ran it in Excel for two seasons, but half the lads kept forgetting to submit their predictions. Now the app pings us half an hour before kick-off and everyone's in."

This approach has proven highly successful in practice. As of May 2026, the platform has 148 active users, with an average of 1.38 prediction pools per user. The format's popularity across different sports is also highlighted by the fact that 12 active pools were running simultaneously during the recent 2026 Ice Hockey World Championship.

Why predict the World Cup with friends instead of using a bookmaker

The main difference between a private league and a traditional bookmaker lies in the very nature of the competition. At a bookmaker, you are always playing against "the house" – an institution with a mathematical edge whose goal is to make a profit. In the app, you compete exclusively against your friends, colleagues, or family members on a completely level playing field.

The crucial factor is the absence of real money. Trefa.app is a free-to-play platform. You don't deposit any funds, there is no risk of financial loss, and the system does not use betting odds. This makes the environment entirely safe, removes the need for identity verification for over-18s, and means it isn't subject to gambling regulations. It is an ideal free prediction game for small teams, allowing younger family members or colleagues who would never use a traditional bookmaker to join in without any worries.

Another advantage is the social aspect. While betting is usually a solitary and isolated activity, a private league acts as a great team-building tool. It provides a natural conversation starter for lunch breaks or evening pints. Furthermore, each group in the app has its own private chat where members can discuss how the matches are unfolding, send reactions, and engage in friendly banter without anyone outside their circle seeing the messages.

How to set up a mini-league for 5–10 friends in 2 minutes

The process of setting up your own group is designed to be as quick as possible. There is no need to fill out lengthy registration forms or invent passwords that you will inevitably forget five minutes later.

Logging in is handled entirely through your existing accounts (Google, Microsoft, or Apple). Once you are logged in, you simply click the button to create a new prediction pool. You give it a name, select the tournament – in this case, the 2026 Football World Cup – and the system instantly generates a unique invitation link in the format trefa.app/join/... along with a corresponding QR code.

You just copy this link and send it to your mates in your WhatsApp group, Messenger chat, or company Slack. When your friends click on it, they go through the same quick login process.

To ensure no strangers can access your private league, the system uses an approval mechanism. As the administrator (creator), you can see everyone who has clicked the link, and you must approve their entry. Only after your approval does that person become a fully-fledged member who can start submitting their predictions.

Which World Cup 2026 matches your league mustn't miss

According to official information published on fifa.com, the tournament will run from the 11th of June to the 19th of July 2026. A massive number of matches will be played over these 39 days, but for Czech fans, the centre of attention will be Group A, where our team has been drawn.

Manager Miroslav Koubek's squad will face three very different opponents. If you are interested in a detailed breakdown of our national team's chances, you can read our article on the Czech Republic at the 2026 World Cup. For your prediction game, the key thing is knowing the exact kick-off times, which are quite specific due to the time difference with North America.

Here is a summary of the three Czech group-stage matches (all times are in Central European Summer Time – CEST):

1. Friday 12 June 2026, 04:00 – South Korea vs Czech Republic (played in Guadalajara, Mexico)
2. Thursday 18 June 2026, 18:00 – Czech Republic vs South Africa (played in Atlanta, USA)
3. Thursday 25 June 2026, 03:00 – Czech Republic vs Mexico (played at the famous Estadio Azteca in Mexico City)

A crucial point when planning to watch the games together: the only group-stage match at a "reasonable" time for a European fan is the Thursday clash against South Africa (18th of June at 18:00). The other two matches take place in the middle of the night. This will test not only the dedication of the fans but also the reliability of the push notifications reminding your league members to submit their predictions before kick-off.

Alongside the Czech matches, your league shouldn't miss the tournament's other major milestones. The opening match of the championship will see Mexico take on South Africa on Thursday, 11th of June, at the Estadio Azteca. The group stages will offer plenty of other attractive fixtures – it will be fascinating to watch Brazil play Scotland in Group C, tournament favourites England in Group L, or the reigning champions Argentina in Group J. The entire tournament will then culminate with the final on Sunday, 19th of July, at 21:00 CEST at the MetLife Stadium in New Jersey.

Ideas to spice your league up

Predicting the exact scores is a great foundation, but any good group of mates loves to tweak the rules to suit themselves. Although the app strictly calculates points for correct scores and match winners, you can easily agree on your own extra rules offline.

A common addition is introducing symbolic rewards. It doesn't have to be anything major – the loser might have to buy a round of coffees, pay for lunch, or get a small gift voucher for the winner. A travelling trophy also works brilliantly. For inspiration: Marcel's pool has 41 members (it's a public league run by an enthusiastic fan), and competing for a physical trophy is exactly what gives their month-long battle its prestige.

Another popular way to keep things interesting is agreeing on "side bets" directly in the league's chat. For example, before the tournament starts, you could bet on who will become the top scorer for the Czech team or who will rack up the most assists.

During the late-night matches, which you will probably watch in smaller numbers or on catch-up, bingo cards work a treat. You can fill them in advance with typical tournament moments – lengthy VAR reviews, tears from losing fans in the stands, or specific clichés from the television commentators. These little extras help keep the group active and engaged even when there isn't much thrilling action happening on the pitch.

Frequently asked questions

Does it cost money?

No, using the app is completely free for standard private groups. You don't pay any fees to set up a league, invite users, or submit your predictions. The app also never asks for any payment details.

Can we split the prize money / entry fees?

The app does not support any financial transactions, collecting entry fees, or paying out winnings. Any wagers for a travelling trophy, a coffee, or lunch must be agreed upon and settled physically amongst yourselves outside the platform.

What if a friend has an Android, not an iPhone?

The platform works exactly the same on both operating systems. The interface smoothly adapts to the screen size, and all features, including the chat and notifications, are available regardless of the brand of phone a user owns. Naturally, it also works perfectly on a standard computer.

Does it work without the App Store / Google Play?

Yes. Trefa.app is a web application. You don't need to search for it in app stores, download bulky installation files, or worry about regular updates. Just open it in your browser (such as Safari or Chrome) and use the "Add to Home Screen" option to create an icon directly on your phone.

What if someone in the group doesn't have a Google account?

Logging in isn't limited to just Google. Users can also use their Microsoft or Apple accounts. Thanks to these three providers, practically anyone with a smartphone or computer can log in without any hassle.

What if someone forgets to predict a late-night match?

The system is designed to notify you about upcoming matches. If a user enables push notifications, the app will send them a timely reminder that they need to submit their score. Furthermore, predictions can be filled in several days in advance and then changed as often as you like right up until the official kick-off time of the match in question.

Does it also work in German / English?

Yes, the app fully supports Czech, English, and German. The great thing is that the language is set at the individual user level. This means you can have a Czech user receiving their morning recaps in Czech, alongside a German colleague who has the entire interface and emails in their native language, all within the same league. Everyone predicts the same matches and appears on the same leaderboard.
