The logic for the AI is:
Easy: afraid of changing color, will only do it when trapped and can no longer move forward. Even when trapped, will move forward until hits a wall, and only then flips the color. Not aware of player (plays as if you don't exist)

Medium: calculates the number of turns it would take without changing color, versus number of turns if flipping once (including the turn spent to flip). Decides on the faster one. When trapped, flips immediately. Also not aware of others, plays as if alone on board

Hard: does the calculation above for itself and also for all competitors in the board, and finds the most dangerous candidate (closer to winning). Instead of deciding the shortest option, it decides the option increasing the advantage compared to the most dangerous. So it may flip the color making it worse for itself if it will make it much worse for you. Playing with several AI pieces makes the game easier since they are not allies, so they may fight each other while you make use of it

You can predict! The sections always rotate in the same direction, which is reverse of adjacent sections. So if first section rotates right, second rotates left, third right, fourth left etc. Also alternate in vertical rows

If this is not happening then we have a bug!
