CASE STUDY / CLIENT WORK
xG Predictor: A football prediction game built around xG
A free-to-play football game where fans predict match scores and expected goals, compete in leaderboards and mini-leagues, and play for a jackpot.
BLUESPACE STUDIO / SOFTWARE ENGINEERINGWhat the client needed.
Make an xG-based football prediction game easy for fans to play while handling match data, scoring and competition rules behind the scenes.
What we worked on.
Scoreline and xG prediction entry, round scoring, leaderboards, mini-leagues, player accounts, jackpot eligibility and football-data administration.
Predict more than the final score
Most football prediction games ask fans to guess the result. xG Predictor goes a step further. For each featured match, players predict the final score and the expected goals (xG) for both teams. xG measures the quality of chances a team creates, so getting close takes more than guessing who will win.
Players earn points based on how close their predictions are to the official figures. An exact xG and scoreline prediction can also put eligible players in contention for a cash jackpot.
The game players see
We worked on the experience from entering a round to submitting a prediction. Players can choose the home and away xG values and final score, change their picks before kick-off, or use an auto-generated prediction. They can also share their picks with friends.
When the match is underway, players can follow the xG. Once official results are available, the game evaluates their predictions and awards points.
Those points feed into weekly, monthly and season-long rankings. Players can see how they compare globally, within their country and among fans of their chosen team. They can also create private mini-leagues, invite friends and compete together.
What runs behind the game
The player-facing experience depends on quite a few moving parts. We worked on fixture and result data, round scheduling, prediction evaluation, leaderboard calculations, jackpot eligibility and the administration tools used to run each round.
We also built supporting notification and prediction-export workflows for the team operating the game. They matter when a round needs attention, but the product itself is about giving football fans a different way to make predictions and compete.
xG Predictor launched publicly in February 2026. We continued refining the game and its operational tools as new requirements came up.
