### 3/5 — False Reviews

*2020-06-06*

As soon as I opened reviews the top two were exactly the same. Others were obviously written by non English speakers, but I thought I’d try it anyway. No possibility to remove ads, but no major influx of them. Controls are simple and well done. Options do not allow anyway to turn off hints and highlights to increase difficulty, they only allow turning on/off the vibration and sound feature.
