Rummy-type games are very popular in some parts of the planet. In the Phillippines, Tong-its is the most successful, and since it was introduced in the 80s it has grown in popularity and this has led to the development of games for Android such as Tongits Offline.
One of the features of this variant of rummy is that it is played by 3 players, has rules that might remind some of the American game tonk and of some aspects of poker and mahjong, and where the main objective is to end up without cards or with as few points as possible at the end of the match.
The game features an interface that recreates a game table, good graphics, and the opportunity to play in three levels of varying difficulty, going from the easiest to the most difficult with a high level of bets. The money you will bet with is, of course, make-believe, but you can buy more at the game store since that will allow you to progress in tournaments and to try to head the global leaderboard.
