This achievement will unlock at level twenty (20), and requires 140,000E XP. By the time you hit level ten (10) you’ll have everything else unlocked and just be looking to gain XP as fast as possible. This guide will help you get the most XP as fast as you can.
First thing you’ll need to know is how to get gold easy. To do this go at least 300meters away from home and do the first photo challenge “Home Photo” (if you have already done it that’s okay you can do it again) take a picture of where you are. The game will think this is you home and now you can do the “Neighbourhood Challenge” from home. Every time you complete the “Neighbourhood Challenge” you’ll net a nice 350 coins.
With the coins you have you’ll want to buy Mineral Water (Drink) and Steak/Chicken Drumstick (Food), if you don’t know where to buy these click the box in the top right and go into the shop. Each time you cub is thirsty or hungry give them these items for 2250 easy XP.
Another easy way to get fast XP is to purchase all the Balls and Jump Ropes in the shop. For each new ball or jump rope your cub plays with you’ll get 750XP. To do this click on the box in the top right corner and swipe right once, any ball or jump rope that has a star beside it means you haven’t played with that item yet. Once you pick the item with a star beside it throw it or jump over it once then pause the game and select “Stop playing with ball/jump rope”. Easy 750XP
EDIT: If you keep playing with your cubs favorite ball or jump rope you can gain the 750XP multiple times after the message "Your cub is having a great time" appears. Thank takuto neko for this info
Another things to keep and eye on for easy XP is the Player Certificate, you can look at this by clicking the icon second from the top left. In the bottom middle you’ll notice it says different thing such as; Dirty, Hungry, Thirsty, Lonely, Playful or Happy. Each one of these will give you XP for doing the correct actions. Here is the list of what must be done and how much easy one will give:
1. Dirty – 1500XP – If your cub it dirty select the box in the top right then swipe left to care items and choose a sponge, now clean your cubs front, right, and left sides till they stand up again all nice and clean.
2. Hungry/Thirsty – 2250XP – if your cub is hungry/thirsty you must wait for them to go off screen and grab a bowl before you give him the Chicken/Steak/Mineral Water. If you feed them from your inventory you won’t get any XP.
3. Lonely – 2250XP – Much like dirty, for this click on your cub and pet them on the front, right and left sides till they stand up again.
4. Playful/Happy – 750XP – if your pet is playful or happy (a lot of the time when I played for some reason) go into your inventory and select a ball or jump rope, now play with your cub until you see the message “Your cub is having a great time” at the bottom of the screen (takes 2 or 3 minutes). After this message pops up pause the game and stop playing with item. Each time you do these pick a different ball or jump rope as I noticed if you pick the same one over and over you won’t get any XP.
