It took me quite a while to get my head around the way the dice moved, and I also didn’t understand what the yellow dice since it wasn’t stated in the tutorial. The dice turn yellow if they are connected and the number of dice that are connected is less than the value on the top face. The value on the top face needs to be equal or smaller to the number of dice.
If you had time, an undo button would be appreciated to help me experiment and better get my head around the way they move.
This was a nice game once I figured that out! Thanks for the fun!
