Pricing

See what things cost

$3 per player to have Manifold show up and run your tournament (the support service), plus surcharges for long-round and long-day events. Manifold subscription tiers exist for other services but the $3 service is flat-rate — what you see is what you pay.

About this place

Manifold Chess started as an in-person chess club in 2022–2023; today it's the chess wing of the broader Manifold services umbrella. Our focus is small operational tools that make hosting real in-person tournaments easy: Swiss pairings via the FIDE-endorsed bbpPairings engine, paper outputs, persistent rating pools for clubs that want their players' progress tracked over time.

Manifold Chess operates under 624984 B.C. LTD., a small BC corporation. Privacy and refund policies are linked below.
