Case study
WiiiN: an online tournament system for tennis leagues
In a classic tournament, losing means you are out. For WiiiN we designed a web app for tennis leagues with its own online tournament system: a bracket in which every player keeps playing matches whatever the results, plus social features.

For WiiiN we designed a platform for playing in tournaments and training. At its heart is a bracket in which every player keeps playing matches regardless of results: winners move to the right side of the bracket, while those who lose carry on playing on the left.

- A platform for amateur and professional players
- A tournament system with a bracket where one loss doesn't knock you out
- Continuous play that supports training and player development
- Social features for players, coaches and organisers
- Tools that make organising tournaments easier
A tournament where losing doesn't end your game, it just moves you to the other side of the bracket.

Goals
01
A shared platform
Bring amateurs and professionals together in one place for tournaments and training.
02
Playing on after a loss
Design a tournament system where every participant stays active regardless of results.
03
A community around the game
Support player development and relationships between players, coaches and organisers.


Who it's for
The platform meets the needs of different groups within the sports community.
- Amateur and professional players - taking part in continuous play and training through regular matches.
- Coaches - tournaments as a tool for developing their players.
- Event organisers - simpler tournament organisation on the platform.
- The community - social features that connect the people taking part.
Tournament system: a bracket where nobody is knocked out
At the core of WiiiN is a bracket that changes how players take part in a tournament.
In a classic tournament, a loss means the end of the game. In WiiiN, winners move to the right side of the bracket, while those who lose keep playing on the left. Every player plays further matches regardless of results, which matters most for training and development.
The player who lost their first match is the one who most needs another.
