True, many people don't know that the grip strength can be tweaked, so that it is loose for x amount of rounds.
This way even if the player aligns it perfectly with the target, the prize will fall prematurely before being delivered to the hole.
So two factors play and contribute to the winning chance: (1) grip strength and (2) positioning. Basically, whether or not the player is skilled, there is still randomness in the game.
Interesting.
In that case I guess there must be some kind of standard or something that can be tested to make sure the machine is working at the correct level of randomness.
At least gambling machines have to pass certain standards criteria to have the license to operate.
Otherwise you could just have the grip always loose and never pay out the prizes.
