Shinkansen Nervous Breakdown is a free puzzle game for Android devices developed by ZOUSAN. It is a picture matching room game for Shinkansen and trains. The game consists of a set of question cards with two pictures of the bullet train, which will transform into a three-car train of the Shinkansen when they align correctly. If you fail to line up the cards, the game becomes a nervous breakdown for solo play.

The game features 20 types of Shinkansen, both new and old, that appear at random. The player can lock the level and fix the number of cards. If you want to play with fewer cards, tap the "Fix number of cards" button. The game provides voice compliments for correct answers and cheers for incorrect alignments.

The game has a time limit and may not operate normally when played too quickly. It is best to play the game slowly and relaxedly. Shinkansen Nervous Breakdown is an enjoyable puzzle game for train enthusiasts who love to test their matching skills.
