The app brings together 7 games from the rummy family. This site covers Rami 40 and Rami 51 in detail; here are the essentials of the other five, as played in the app with the reference rules. Each game also has its own help page in the app.

Melds: groups of cards of the same rank, no runs. Twos and jokers are wild cards, with at most 3 per group.
Canasta: a group of 7 cards. Without wild cards, it scores 500 points; with wild cards, 300.
Initial meld: a minimum that depends on the team's score (15 if the score is negative, 50 below 1500, 90 below 3000, 120 thereafter).

Gin Rummy
Players: 2, with a single 52-card deck and no jokers; 10 cards each.
Basic idea: melds stay in your hand. You may knock when your unmatched cards are worth 10 points or less.
Gin: all cards in melds; you score the opponent's unmatched card points plus a bonus of 25, or 31 with 11 cards in melds.
Undercut: if the opponent has as many or fewer unmatched card points than the player who knocks, the opponent scores 25 points plus the difference.
End: the first player to reach 100 points; a game bonus of 100 (200 if the other player has scored nothing), and 20 points per round won for each player.
Buraco Aberto

Canastra: a run of 7 cards. Without wild cards 200 points, with wild cards 100; a clean thirteen-card run 500, a clean fourteen-card run 1000.
Bonuses and penalties: going out (batida) 100; morto never taken, subtract 100 points.
End: the first team to reach 3000 points. Above 1500 points, the team must lay down at least 75 points for its initial meld.
