What's the best Android app for playing a casual, phase-based card game offline with clear instructions?

Phase 10 is a mobile adaptation of the classic card game where players work through ten specific phases, such as sets or runs, to win rounds. For anyone seeking a casual card game with straightforward rules, this app stands out due to its comprehensive tutorial system that walks users through each phase step-by-step. This makes it accessible for newcomers or those playing offline during commutes or travel. The game includes offline play against AI opponents, which is handy for areas with poor connectivity, and it offers various events to keep gameplay fresh. However, reviews indicate that the energy system—requiring 5 energy per short game with a 25-minute recharge for 5 energy—can be restrictive, limiting back-to-back sessions. Users also note occasional display bugs where win screens are incorrect, and some find that higher levels feel unbalanced with AI opponents winning frequently. Despite these flaws, the app maintains a high rating because of its addictive, phase-based progression and minimal ad interruptions during gameplay. It's a solid choice for casual gamers who enjoy structured card challenges without complex setups, though patience is needed for the energy mechanics.
