What's that sound? It's 4 Amusement Only, the EM and Bingo Pinball Podcast. Welcome back to 4 Amusement Only. This is Nick Baldridge. Tonight I wanted to talk about 1970's Bonus 7 by Bally. Bonus 7 is a follow on to Super 7 and as such it includes all the features from Super 7 including Advancing Odds from 4, 16 and 75 all the way up to 192, 480 and 600. Pick a play to advance either odds and features with the red button, features only with the green button or odds only with the blue button. Mystic lines to allow you to swap the leftmost two columns with B, the center column moves up and down with A or the rightmost two columns with C, doubled or tripled odds in any one color, an extended time tree from before fourth to before fifth to after fifth, twin numbers twelve and seventeen and eight and ten which when you hit one the other will light automatically, Numbers lit in all four of the star zones award either 300 or 600 replays and your red letter game in the word bonus and the number seven. Any three numbers in the star zones will award it or any two. And if you get the red letter game, what happens is you hold the R button down and all your balls will drop and then the game will award you a brand new game for free with guaranteed odds and features The big draw for this game is the bonus game aside from the standard MysticLion gameplay This you coin up with the white button and this is a solid state feature. Your goal in this game is to get seven. You do so by shooting your first two balls and landing them in two holes which equal the The number seven. When you do so, this qualifies your win and you can either take it and earn anywhere from two replays up to seventy-two or shoot for a red outlined hole in which case you go from four to a hundred and forty-four, doubling your odds or you can double it again. Shoot for yellow outlined hole and you can get anywhere from 8 to 288 replays. If you shoot again and land in a red outlined hole you can get anywhere from 16 to 576 replays. Now, that bonus feature, the bonus 7 game is pretty cool and it sounds really difficult and so I really want to try it at some point. But aside from that this game adds another feature. Three of the numbers on the back glass are outlined with these little sunbursts. And if you have the feature lit, if you light up the number in all three of the sunbursts then the next game will award you maximum odds for the bonus seven game automatically. In some instances it light only two of the sunbursts are needed for the top scores awarded the top odds for that bonus seven game Now from what I read apparently it fairly easy to get this lit up So that would be something that you would definitely want to shoot for because it makes it so that you have nothing to lose by playing that bonus seven game. The only thing that gives you pause or should give you pause about playing these special games is that they really hinder the gameplay of the standard MysticLions game and because of this it probably makes it very difficult to win using your standard MysticLions gameplay so let's talk a little bit about that. What is the standard gameplay? I just jumped right into features. You come up and you drop a coin and the game is going to load a ball into the shooter lane. At this point you can either shoot the ball and play for your default odds or you can try and increase them with those pick-a-play buttons I was talking about. After you shoot five balls, if you have three, four, or five in a section that matches the color of the odds, then you'll win that indicated number of replays. But remember the Insidious evil star zones are back and they count for nothing unless they are the fifth in that section or you have one of the starzone features lit that I talked about earlier so after you shoot your first five balls you can make a decision do you want to move on to the next game or do you want to play for extra balls if you do you push the yellow button and then start depositing coins And eventually it light first extra and ball and it will lift your first extra ball to the playfield You can get up to three So let talk about artwork This game has almost exactly the same artwork as Super 7. The only difference is that the outline square around the bingo card, instead of having alternating blue lines, has alternating green lines. And then on the cab, instead of brown as a base coat, you have green. And something I didn't mention last night is on the head, there's a stenciled 7. The playfield is brown and again, instead of the alternating blue color, you get alternating green. The artwork on these games is rather plain, but the gameplay sounds pretty outstanding and difficult. So it's not something that should be dismissed simply because of a lack of really, really beautiful artwork. And there's nothing wrong with this artwork. It's certainly serviceable, but at least for me, I certainly like to have artwork that's a little more Um, inventive. Well, that's all for tonight. Thank you very much for joining me.
