"Easy! Mahjong Solitaire" is a simple puzzle game that utilizes mah-jong tiles. With an easy-to-follow rule, players can enjoy the game anytime and anywhere. The game starts immediately upon launch, and players have the flexibility to pause and resume at their convenience. The absence of menu panels or option screens allows for instant gameplay enjoyment.

The gameplay rule is straightforward, distinct from "Shanghai Mahjong." Players need to pair up identical mah-jong tiles on the screen to clear them all. The selection process involves directly touching the tiles with your finger, following specific conditions for tile removal. The game ends in a "GameOver" if no more valid moves are possible, prompting a shake of the iPhone/iPod touch for a new game to begin. Additionally, as players progress, they encounter increasingly challenging puzzles and a Time-Attack mode for a faster-paced experience.
