Peaceful

Peaceful is a vertical jade identification puzzle mobile game. The gameplay is simple yet increasingly tests your eyesight as you play. Each round, four rough stones of similar appearance are displayed on the screen. Players select one stone and press to open a window, observing the internal glow and veining through the cut, judging whether it is genuine jade with a greenish hue, or a fake disguised with yellow light, white frost, cracks, or brown veins. Correct choices add points, while wrong choices accumulate mistakes; three mistakes end the round. As the score rises, the features of genuine jade and fake stones become increasingly similar, requiring more careful discernment. Suitable for quick sessions in spare time, and also for challenging higher records across consecutive waves.
