Catching a beast is very easy if you know what you are doing.
Finding a BeastEdit
To find a beast then slide the front of your device up and spin it round. There is a bar at the bottom showing you how close you are to a beast. When it fills up, a beep noise will occur and a capture will begin.
Capturing your BeastEdit
To capture the beast, spin the device until the beast is on-screen. Then, using the reel at the side of your Catcha Beast, spin the reel and chase the beast (by spinning the device) until it runs or gets captured.
