RULEBALL

Choose a rule. Change the match.

Pick Barn Doors and both goals become twice as wide. Against a squad built around Snipers, their deadly accuracy suddenly matters less. Every rule affects both teams; your edge comes from choosing one that better fits your squad and the matchup.

Combine 28 rule cards with 12 player traits. Card synergy hints come from simulated matches.

One club, three leagues, three cups

Lead your club through Sunday, Pro and Legend: five matches per league, or 15 matches on a winning run through the whole campaign. Meet 15 rivals, different squads and three distinct finals. Strengthen your team in the transfer window between matches.

Decisions beyond the pitch

Choose a starting style: speed, power or tactics, each with its own strengths and trade-offs. Take the safer route or face a stronger rival for an extra reward if you win. Consider offers from a scout, sponsor or trainer. See the terms and costs before deciding. Complete three contracts and collect local badges for your club cabinet.

After a title, carry one offered rule card you own or one offered player into the next stage — or choose a fresh start. Your first title also opens a pool of eight additional rules to acquire in later seasons.

The Legend title is not the end. Compete for more cups with one chosen condition: stronger rivals, a smaller starting budget or elimination after your first defeat.
