I was intrigued when I saw the information on Pindemption, and at first thought $200 was a lot of money for a software update, but I like short games EM's as much or more than modern games, and since time is sometimes scarce to play a long good game on WOZ, I decided to order the dongle. I should mention that I have no desire to ever operate my WOZ in a redemption center or on location, so this software is strictly for home use.
Installation was super easy and no issues afterwards, and I am extremely pleased with what it gives me, a timed game where can shoot for goals and keep track of how I'm doing in terms of tickets, so far my record is 71 in a 2 minute game. Melting the Witch is a relatively easy goal to reach, but still very satisfying and pays off well.
I can see WOZ killing it in a redemption center with this software installed, it really has some play value that most of the redemption games don't have, and I found I kept wanting to play just one more game which of course is what redemption centers want. It'll never beat the ripoff games which give about 2 seconds of play, but should hold it's own with games that do have some form of play.
My only wish is that for a home game there was a point system instead of tickets, but maybe that will come in the future.
Overall, I think Pindemption is a great add-on to WOZ, gives you a great option when you just don't have time for full game.
