### 3/5 — Intriguing... but not challenging

*2021-02-28*

It is fun for a single game ... but it feels to me that the AI is simply looking for places where pieces can fit (a visual and geometric exercise) rather than calculating outcomes many steps ahead, and/or blocking competitors’ corners and areas of expansion.

### 5/5 — Great but a couple things

*2020-12-19*

Hello,
Thank you for making this app! It’s great and allows my family of 3 to play.

Just a couple things I thought I would like to share to help improve the app:

•I have noticed the computer has been designed by which it’ll choose to play pieces which don’t help it through the maze of the opponents to help win and will choose pieces which only block the opponents (for example, playing a two piece which blocks an opponent but prevents it from continuing its game rather than playing a three piece which can help it continue and block at the same time). In short, it sometimes comes off as being an unintelligent AI and I believe you could easily change this.

•We use a slightly older version of the board which is a silver grey rather than white and the app does not recognise it. I have tried the app on both a newer board (white) and an older board (silver grey) and it’ll only recognise the newer board. I use another app to play the game on my phone at the same time and use the screenshots of the app to get around this but would love it if you could maybe improve the camera reading ability? I don’t know how easy it would be to sort.
