Yes it is! The thing it prioritizes changes based on the AI type: it can either be defensive; Prioritizing hoarding dices, or offensive; closing in on the player. Smarter AI also knows what is the best player move, and the optimal dice to use; preferring more common dices over others.
It's easy to underestimate the amount of strategy that, what can look like a random game, has to offer. Understanding its logic, and the basics game mechanics, enables you to win almost 100% of the games. ;)
