So glad I got to buy this to play. Very fun non pitch and bat baseball pin. Probably my favorite. Todd tuckey has a video on game play but it has super fun rules, great logic and shots. I love the fly away targets and the spinner shot to advance runners. This might be one of my favorite games from the early 80s. If you get a chance to play or buy one don’t pass it up. Watch the gameplay video before and it will all make sense when you play it. Excellent pin

i think pinball machine is pretty good.
But its also so hard to come by.
its worth a buy if like baseball theme pinballs but maybe not for people looking for a challenge because it is a bit on the easy side.

the design is done by Greg Kmiec who also designed other more well known pinballs such as Capt. Fantastic and The Brown Dirt Cowboy and paragon. The design is different then others with a reversed inlane/outlane on the right side and lack of left and right slingshots kickers in the slingshots so the ball just slowly bounces off the instead of shooting away into a target .I do like the targets in the middle that you hit that spell "HOMER'. You knock them down and it rewards runs which act as the bonus points. So most targets don't give much points expect to add runners to bases which hitting "HOMER" will reward those runs at 10,000 points per run.

I do like the skill shot flipper on the upper left.You can make the shot by hitting the loop on right with spiner to add runner then time it right to into the upper play field to lite grand slam homer.the often drops into the saucer hole which shoots it toward the upper left flipper for a difficult skill shot.

The artwork is more on the simple side but it still fits the theme well. The artwork is done by Doug Watson who also designed the Barracora and f-14 tomcat artwork.

This pinball was made in 1983 by bally. This pinball was made as an "economy" game, meaning that there wasn't a lot of extra money put into the game, neither in design nor promotion. Only 1'000 were known to be made.

Awesome fast game. Lots of fun. Glad I found one.

Some people might not be too excited about playing this game because it's theme is baseball. However, if you like baseball and/or sports-themed pins, then Bally's Grand Slam is a great choice. The rule set is very intuitive, and follows the scoring rules of baseball. The pin requires quite a few different skill shots, and is a good game to compete against your friends. My opinion is that the 2-player pin is a better choice than the 4-player, because it becomes one "team" against another "team". The game really shines when you play with friends, because you can set-up a World-Series type tournament. I believe the Grand Slam pin is a great game, which combines the features of a pinball machine with some of the feel and scoring of a "Pitch and Hit" baseball arcade machine.

Pretty good for the time period. Timing the "pitch" is pretty damn hard and that little top flipper is no help. Nice playfield, you can hit homers and such with certain shots. You also need to score runs to win, fun two player game.

Not all that challenging. I did pretty well not knowing rules or play at all. Very lame backglass and sound that has zero to do with baseball. Fun but not worth owning.
