So you want to get Jackpot! but not really bother with trying to time the slots, and at the same time get Fever! as well?

Then this is the guide for you!

Triggering a Fever in the slots requires your score to be in a specific designation. If your score ends in an even number, like 1000, 2000, 5000, etc, then it will trigger a fever, netting you that achievement.

But how then do you trigger a Fever with nothing but Galaxians?

Well, you do that by ending your score with 765. Yes, that specific value.

It can be 1765, or 3765, or 10765.

It doesn't matter. It has to end with 765.

And by doing so, you'll trigger a Fever with Galaxians!

The best way to go about doing this is by going to World 2-3 "Corsair Cove". Near the end of the level, there are two skeletons, one in chrome and another normal. Killing either will give you 200 in your score.

Each pellet you pick up is worth 5.

A fruit is worth 300.

Just do the math while you're running around and you're going to be able to get this achievement in no time.
