The thing that really pissed me off is that the claw-grab machines are now based on payout percentages and rather than actually being a game of skill.
"Stacker" as well. Learned that the hardest way possible.
Well, gambling is a luck-based game and this pretty much puts the luck in what is supposed to be a luck based game. Casinos aren't obliged to give their customers money if those customers know a neat trick, y'know.
They are, however, expected to make the machines fair and up front about what they're doing. Randomly rejecting the user's inputs because of knowingly bad hardware isn't part of that deal.
The reasonable thing to do would be to disable that play mode altogether, not rig it.
Casinos are obliged to give their customers money if they win the game. If there's a "problem" with the game that makes it easier to win then it's in the casino's interests to change it and eliminate that problem.
