Card tournament organizing, in your pocket
What is this?
DeckDelve is a free tool for judges and organizers running card game tournaments — Magic, Pokémon, One Piece, Union Arena, Yu-Gi-Oh!, Lorcana, or any TCG. Seat players with drag and drop, run timed Swiss rounds with real tiebreakers, and hand the whole event to another judge's phone with a QR code.
Your data stays yours
No accounts, no sign-ups, no tracking, no ads. Tournaments live only on your phone and move only when you show someone a QR code. Once loaded, DeckDelve works fully offline — even in venues with no signal.
☕ Keep it ad-free
DeckDelve is built and maintained by one person and will never show ads. If it saved your event night, a small tip keeps the lights on and new games coming.
