THIS IS FOR YOU IF You run tournaments, league nights or larger organized-play sessions and want the seating​/​standings layer handled in one place. THIS IS NOT FOR YOU IF • You need a rules engine or automatic hand scoring • You need a two-player mode • You need cloud sync between devices • You expect an annual card, hand list or official tournament rules • You want a mobile app or installed desktop app IMPORTANT You enter point totals yourself. The tool does not judge hands or teach play. For some player​/​round combinations, zero repeats are mathematically impossible; the tool reports the repeats it could not avoid instead of hiding them. LICENSE One purchaser may use the files on their own devices and run as many of their own events as needed, including paid-entry events. Resale, sharing, gifting or redistribution of the files is not included. This is version 1.0. Future updates are not promised as part of this purchase.
