I run a draft league association and their 7s Developmental League on site. Multiple draft leagues play a preseason tournament and a regular season separate from each other. The winner of the tournaments and the regular seasons receive autobids to the highest level of playoffs. The highest tier of playoff is called the Bloodbowl Champions' League and there they play in a group stage and knockout round like irl UEFA. The runner ups play in the mid tier playoff in the form of a round robin called the Roz El Cup. The rest of the teams will play in the low tier knockout tournament called the Major Blood Bowl Invitational.

The current leagues in order of establishment.

Ulthuan First League (UFL) is an elf based league with a common roster comprising standard and secret league elf players.

Kislev Premier Alliance (KPA) is a league of secret teams, but does not allow stunty teams.

Imperial Bloodbowl Association (IBA) is a league of standard teams + Slann & Bretonnian rosters, but does not allow stunty teams.

Xtreme Lustrian Bloodbowl (XLB) is a league of stunty teams only.

Planned leagues

Naggaroth Football League (NFL) is a rotational premiership league that incorporates the regular season champion from the prior season of each associated league. All members of the NFL's season play in the BCL tournament. It is a bragging rights league that ties the association together and takes away perrenial powers from their home league the next season so that new teams can rise in their absence. It will be promulgated once there are 6 leagues within the association for scheduling purposes.

Tilean Super Confederation (TSC) is a human based league with a common roster comprising standard and secret league human players that add in x2 blockers.

Arabyan Football Union (AFU) is an orc based league with a common roster comprising standard and secret league orc players.

Developmental League

National Collegiate Bloodbowl Association 7s (NCBA 7s) is a 7s league based on NCAA college football in the US. The only limitations are client sized field, 11s kickoff events, and 8 turn halves. However, it is a great way to play. In any case, the players cycle into the 11s draft of which all teams are involved with.
