Phagefight

The Good
An Ataxx variant, easy to learn, difficult to master.

In all its simplicity, it has enough options to make things challenging. The AI is fully configurable between aggressive and defensive stances, and overall intelligence. The author claimed he couldn't beat the AI on highest level.

And it has 20 different boards with different obstacle positions to make things even more challenging. One obstacle will change an entire strategy.

The Bad
The graphics might be too simple even for a self-made game, and the colours might not have been the best chosen.

The Bottom Line
If you like those games you can learn in 10 seconds and you can't beat in 10 attempts, this game is for you. A small board, you against the computer (or against a friend), move your pieces 1 space for duplication or jump 2 spaces without it; touch enemy's pieces for conversion.

It's that simple. However, what this game has to stand out from other Ataxx variants is not visual, but under the hood. The AI is surprisingly good even at low levels. Highly configurable too.

In conclusion, nothing new or visually impressive, but extremely well executed. A must try if you like this kind of games.
