A head-to-head bingo board for two OSRS clans on the same tiles at the same time. Free 5x5 board, plus the rules that keep a clan battle fair.
Clan versus clan is the format that turns a quiet bingo into a rivalry. Both clans run the same board, over the same window, and the comparison is direct - which is exactly what makes the tile selection harder than for an internal event.
Any tile that depends on something one clan has and the other does not decides the match before it starts. A board with four raid tiles is a win for whichever clan raids. The pool below is deliberately spread, so neither side can pick its own strength.
Agree the board together and publish it to both Discords at the same time. A board written by one side is a board the other side will dispute at the end.
Normalise for size. Either cap the number of counted members per clan or score tiles-per-member rather than raw totals.
Appoint one host from each clan and have both approve every submission. Cross-approval removes the single biggest objection to a loss.
The board above is drawn from this pool. Swap any tile for another at the same difficulty and the points stay balanced.
Both clans play the same board over the same window, with tiles agreed in advance, one host from each side approving submissions, and a size normalisation so a 100-member clan is not competing against a 20-member one on raw totals.
Cap counted members, or score on tiles completed per active member. Both sides agree to it before the start, in writing.
This board is free to copy, edit and post. Tracking 25 tiles across a clan - submissions, screenshot approval, team standings, Discord updates - is the part that eats a host's weekend. An OSRSHub server does that for $12.10/month.
