I just finished shopping Soccer Kings, so I haven’t had a ton of time on it; but so far so good.
The game plays fast and is easy to figure out: Hit down the drop targets to gain “kicks” at the goal on the upper playfield. Goals advance the red special target. ABC targets advance the Orange special. Rollovers activate “super scoring” for a short time.
Definitely the upper playfield is the coolest feature of the game. I like how they put in a moving blocker for the goal. It’s also neat that the upper playfield has an on-demand ball through; You don’t actually hit your ball up there. There are 4 balls in a through behind the goal; waiting in queue. The ball you hit into the upper hole just goes down a small subway and waits till you run out of kicks (displayed on a mini digit display).
The call-outs are a soccer announcer like you would hear on TV. The sound effects are unique; as most gen2 zaccaria games. The art on this game is more basic compared to other Zacs, but still nice a vibrant colors. I would compare this to Devil Riders: Not as cool of an art package, but a much better player.

Soccer Kings is another creative and colorful game from Zaccaria.

The Pros:
Tight target shots on the sides and challenging shots up and across the PF from all 4 flippers. Drops at the top and loops mean that the ball moves fast and slow depending on what you are shooting for. The white disappearing kickout from under the PF moves fast, you'd better be ready!

The Cons:
I wish there was more to do on the upper PF other than a single shot to the goal. Seems like an awful lot of work for just that one target up there. The player on the BG looks like he's made out of clay.

The Takeaway:
A good game, but not one of Zaccaria's best players. IF you like soccer though... this one may do the trick for you.
