The bot levels are very well set. A person playing for the first time can use Level 1 to train themselves, and understand the kind of thinking that is needed for winning. I found Level 8 challenging. Lost more games than won. Then there is Level 10 for the enjoyment of someone who has mastered the game. Short games, challenging, fun filled and not much distraction through ads.

I've played this game for years and the only thing missing was loads of adverts. Thanks to the recent update though, I can assure you all that there are now plenty of ads getting in the way between games and even after play has started. Great for people who like adverts getting in the way.

Sorry for your experience but app last updated April 2023 and we haven't changed anything with ads. Popup ad appears between games so it does not disrupt play. We tweak ad timings to try and avoid inadvertent clicks from badly timed ads but it is a work in progress. Please report bad ads to support@aifactory.co.uk. Paid version has no ads.

Good version, although it appears to be set so that the CPU always goes first. So far, there are only ads in between games, and they're very short. Time will tell if they get more intrusive...

The darker colour piece always goes first and you can choose to play as darker, lighter or alternate between games. Just choose Game Menu > Main Menu at the end of a match or leave a match any time with device "back" button, then go to Single Player and change "Play as" setting. Hope that helps
