### 5/5 — Great

*2026-06-06, version 1.8.1*

I’ve played this for few years when I need to waste some time. Aside from the layout being clean and simple, my favourite part is that I can play it when I have no internet access. For example…. Stuck in a toilet with no WiFi or data 🤸🏻‍♀️👻

### 5/5 — Neat & clean

*2026-05-18, version 1.8.1*

This game is very simple and clean. I played this on my android for years. For devs please make the setting same as the android app where you can hide the time counter, circle locked cells, and layout setting. To hide the time counter is all i need XD
