The idea is original, imho could be more fun if it was applied to minigolf and one could deliberately bounce off obstacles. The dice confuses me though. I would expect that rolling 10 would make the ball go to the max distance limit of a given club. But instead, that often means going out of bounds and a roll of just a 5 will get me to the edge.

Rolling 10 will grant you maximum possible distance of the selected club. Each club has minimum and maximum distance - this is indicated by the two dashed circles.
On top of this, there is always "random" variations of the distance and angle based on starting terrain (smaller chance of clean hit), club and landing terrain - ball can roll after hitting the ground and will roll more on fairway/green then on rought grass / sand.
Also, the randomness is larger for higher numbers rolled and there is bigger chance not to swing perfectly. This is intentional as it is more true to reality...
Maybe this should be more deeply explained in the help.
