How to Create a Prediction Pool: A Complete Step-by-Step Guide (Rules, Scoring, Software)

A prediction pool is a popular social game where participants predict the outcomes of sports matches. The goal isn't to win money, but to rack up as many points as possible and land at the top of the leaderboard. This article walks you through how to create a prediction pool from start to finish - for friends, colleagues, or a sports club.

Whether the Ice Hockey World Championship, the football Euros, or a new Premier League season is coming up, a prediction pool adds an extra layer of excitement to watching sport. We'll cover the rules, the scoring, and how to pick a tool that can save you dozens of hours of work.

What a prediction pool actually is (and isn't)

Before we get into how to create a prediction pool, let's get the terminology straight. At its core, it's a points-based competition. The organiser (the admin) picks a sporting event - say, a hockey league's play-offs. Before each match, participants predict its exact result ("the home side wins 3-1"), and once the match ends, points are handed out for accuracy according to rules set in advance. Whoever has the most points when the tournament wraps up wins.

The crucial part is that no money is involved, which is the fundamental difference from betting with a bookmaker. In a pool, you're playing for points, bragging rights, and maybe a symbolic prize (a bottle of wine, a travelling trophy); with betting, you stake real money against a bookmaker at fixed odds. Because there's no financial stake, a prediction pool is completely legal and safe to run - a company can organise one for its employees, a school for its students, or a group of friends at the pub, without a second thought.

Three ways to create a prediction pool

Once you've decided to run one, you have three options for managing it, each with its own trade-offs.

1. Pen and paper

The oldest and simplest method: a sheet of paper, a pen, and a ruler. Draw up a table with participants' names and a column for each match, and score predictions by hand once each match finishes.

• Pros: zero technical overhead, ideal for a small group over a single weekend.
• Cons: tedious for longer tournaments (a football World Cup with 104 matches, for instance), prone to counting errors, and there's no running leaderboard unless you recalculate it by hand every time.

2. A spreadsheet in Excel or Google Sheets

The classic choice for anyone who wants a bit of automation. You build a spreadsheet where participants fill in their predictions, and formulas can award points automatically.

• Pros: flexible, free, and easy to share online.
• Cons: requires a decent grasp of formulas, you still enter results by hand, and people constantly forget to submit their predictions, so you end up chasing them. See our full comparison of a prediction league versus Excel.

3. A dedicated app (like trefa.app)

The modern, most convenient option. A web app built specifically for prediction pools handles most of the work for you, from loading the fixture list to the final scoring.

• Pros: full automation. Fixtures and results load automatically, the leaderboard updates after every match, participants join easily via a link, and push notifications remind them so nobody forgets to predict.
• Cons: you're limited to whatever features the app offers. That said, a pool is free for any number of players. You only pay for extra features.

For a one-off event with five friends, pen and paper will do the job just fine. For a company competition with 50 colleagues, a dedicated app is realistically the only sane choice.

How to create a prediction pool step by step

Let's walk through the whole process, from the idea to announcing a winner. This guide is universal, but it works best when paired with a dedicated app.

Step 1: Choose your competition and matches

The first decision is what to predict. You've got two main options:

• A short tournament: the Ice Hockey World Championship, the football Euros, the Olympics. These work well because they have a clear start and finish, and they draw in even people who don't normally follow sport. See our World Cup 2026 prediction game hub for an example.
• A long-running league: the English Premier League, or a national hockey league. A pool like this runs for months and suits die-hard fans more than casual participants.

In an app like trefa.app, you simply pick a competition from a list and the system loads the full fixture list and dates automatically.

Step 2: Set clear rules and scoring

This is the most important step. The rules need to be simple and clear to everyone from day one, since well-designed scoring is what keeps the competition exciting right up to the final match. In an app, you just click through a few settings to decide the points.

Step 3: Invite participants

How do you actually get people into the game?

• With an app: generate a unique invite link or QR code and send it by email, WhatsApp, or Slack, or pin it to the office noticeboard. People join with a single click - on trefa.app they sign in with their existing Google account, so there's no form and no password to forget.
• With a spreadsheet or on paper: you have to share the file, or track everyone down in person, and add names by hand.

Whether you're running a prediction pool with friends or a large office competition, the key is making it as easy as possible to jump in.

Step 4: Predict, watch the leaderboard, and enjoy

Once the competition kicks off, everything runs on its own (assuming you're using an app). Participants submit predictions before each match, and once it ends, the system updates results and recalculates the leaderboard automatically. Watching the standings shift and needling your colleagues about it is honestly the best part of the whole thing.

How to set up fair and fun scoring

Good scoring is the make-or-break element of any prediction pool: it should reward accuracy while still giving a slow starter a real chance to come back. Here's a tried-and-tested model, similar to what most apps, including trefa.app, use by default.

Basic scoring per match

• Exact score: the biggest reward. You predict 3:1, the match finishes 3:1. (e.g. 5 points)
• Correct goal difference: winner and margin right, but not the exact score. You predict 2:0, the result is 3:1. (e.g. 3 points)
• Correct winner or draw: right on who wins, wrong on the score or margin. You predict 3:0, the result is 1:0. (e.g. 2 points)

It's also worth adding a bonus for correctly calling a draw, since people tend to under-predict them.

Bonus questions

To keep the competition exciting all the way to the final, add bonus questions that only get scored at the end of the tournament: who wins it, who ends up top scorer, how many goals are scored in the final.

A tip for admins: whatever system you choose, explain it to everyone up front - it saves you from arguments and confusion later. For a deeper dive, see our guide to scoring rules for a company prediction pool.

Who is a prediction pool for? Three real-world examples

1. A company prediction pool. A great, low-pressure form of team building. People from different departments who don't normally cross paths suddenly have something to talk about, and the healthy competitiveness helps too. It's far cheaper than a big company event, and since no money is at stake, it's safe from an HR standpoint. See our worked example: a company hockey pool for 2026.

2. A prediction pool with friends. The classic setup: a group of mates, a WhatsApp group, endless trash talk. The winner gets the glory, the losers buy the next round, and with an app there's no more arguing about who predicted what.

3. A sports club or community. Want to get fans, parents of young players, or club members more involved? Run a pool around your own team's matches or a major tournament - a great way to build community.

Common mistakes when setting up a prediction pool (and how to avoid them)

1. Overly complicated rules: nobody understands how points are calculated, and people lose interest fast. Fix: stick to a simple model (exact score > goal difference > winner).
2. Irregular scoring: forget to update a spreadsheet for a couple of days and enthusiasm fades fast. Fix: use an app that automates it for you.
3. Poor communication: participants don't know the deadline or where to find the standings. Fix: use a tool with automatic reminders and a clear, always-current leaderboard.
4. Choosing the wrong tool: running a 100-person pool on paper is a nightmare. Fix: weigh the group size and tournament length, then choose between paper, a spreadsheet, and an app accordingly. See how it works for the full picture.

Frequently asked questions

What is a prediction pool?

What do I need to set up my own prediction pool?

Three things: a sporting event to predict (such as the Ice Hockey World Championship), clear scoring rules, and a tool to manage it - pen and paper, a spreadsheet, or a dedicated app that does most of the work for you.

How do I set up scoring in a prediction pool?

Most pools award the most points for the exact score, fewer for the correct winner, a draw, or the right goal difference. You can also add bonus questions, such as who wins the whole tournament.

How do I invite people to my prediction pool?

With an app, you just share a unique link or QR code, and participants join with a single click. With a spreadsheet or paper version, you have to reach out to people and add them by hand.

Do I have to score the results manually?

No. Paper or a spreadsheet require manual scoring, but modern apps like trefa.app do it automatically - as soon as a match ends, the system recalculates points and updates the leaderboard.

Can I run a prediction pool in Excel?

Yes, and it is a common choice, but it has real downsides: manually building the table, writing formulas, constantly updating results, and distributing the standings. For larger groups or longer tournaments, that is a lot of work.
