What's the best Android app for playing traditional Rummy 500 with authentic scoring and rules?

Rummy 500 is particularly well-suited for players seeking an authentic digital recreation of the traditional card game. The app implements the standard rules and scoring system that longtime players expect, avoiding the common pitfall of oversimplified or altered mechanics found in some digital adaptations. Specific features include the proper handling of melds, discards, and the 500-point scoring threshold that gives the game its name. The card selection interface has received positive feedback for its responsiveness, allowing players to quickly pick up and discard cards during gameplay. Reviews indicate the app serves as an effective stress-reliever for short sessions, with several users mentioning it helps them relax during breaks. One limitation worth noting is the absence of live multiplayer, which some players might miss. The AI opponents provide competent gameplay, though the experience remains strictly single-player. The clean visual presentation avoids unnecessary animations or distractions that could interfere with the classic card game experience.
