### 5/5 — The best way to play puyo puyo on mobile

*2019-06-11, version 2.5.2*

It’s great! There are a lot of customizable features and my only complaint is the lack of special pieces like in puyo puyo 2, but it’s simple, fun, and a great puzzler

### 5/5 — Holy Crap this is amazing

*2019-05-23, version 2.4*

This is honestly the perfect puyo simulator if you are trying to learn or just play casually. It has no gravity and even has undo/redo buttons. The minimalistic pixel puyos are so cute as well. What more can you ask for?

### 5/5 — Awesome discovery
