How to Play Pachio-kun - Puzzle Castle
Quick start
Try a stage-clear goal first and practise A rotation separately from B picture swapping. D-Pad: position the falling pair. A: change the pair's orientation. B: swap its two pictures. Plan the conversion before placing it: falling after a clear does not start an automatic chain.

Pachio-kun - Puzzle Castle — About this game
Pachio-kun: Puzzle Castle is a falling-block puzzle built around reversals. Matching characters placed on opposite sides turn the intervening family blocks into their own kind; a line of at least four matching blocks then disappears. The P emblem and obstructive Boruzo blocks complicate those conversions, and falling blocks do not trigger the usual automatic chains. Rotate a pair and swap its pictures separately to prepare the next enclosure. High-score play develops a castle town, while stage-clear play sets specific puzzle goals.
