If you want more (and better) parts in C.A.T.S. - Crash Arena Turbo Stars, you need to earn an unlock boxes. Duh, right? But do you know what crowns are for and how to earn them? Have you been opening boxes super fast by watching videos? No? Maybe you should read this C.A.T.S. - Crash Arena Turbo Stars Boxes and Crowns guide. Just sayin'....
C.A.T.S. - Crash Arena Turbo Stars: Boxes
Boxes are fundamental to the C.A.T.S. - Crash Arena Turbo Stars gameplay loop. You use parts to build your car, that car fights other cars, and then you earn boxes with new parts to build a better car. So on, into eternity (or until your battery runs out).
There are a few different types of boxes out there. The simplest boxes are awarded from playing in the Quick Fight matchups. Every time you win 3 Quick Fight matches, you get a new box. However, you have a limited number of box slots, and these boxes take time to unlock.
You can skip the timers on the boxes by watching ads. Each ad takes 30 minutes off the opening time of the box. That means that if you've got an especially high tolerance for watching ads (and unlimited data on your phone, a charger, etc...) you can open ALL THE BOXES ALL THE TIME CONSTANTLY.
Pro Tip If you have multiple sources of entertainment (ie, a TV or game console, laptop, etc) you can always just let your phone/tablet watch ads. You just have to check in every 30 seconds or so. Even if you just start a new ad every commercial break during a show, you're still drastically increasing the rate of box opening.
C.A.T.S. - Crash Arena Turbo Stars: Crowns
Crowns in C.A.T.S. - Crash Arena Turbo Stars are kind of a cool concept. You earn a crown for every 5 consecutive wins in Quick Fight mode. These crowns are then stuck on "standard" boxes in your box slots.
These crowns increase the level of an item in the box. Multiple crowns can be applied to the same box. It's actually possible to get parts that are stronger than your Championship level with crowns.
If you're wondering why you would want to play Quick Fight matches when your box slots are already full, look no further. Getting a quick 5-win streak in Quick Fight is a good way to "guarantee" at least one better item than you would have normally gotten. It can make the difference between a mediocre box of parts and a truly amazing one.
