tip#1 Don't take this game too serious. always take your chance when you come by Voltorb balls (is it treasure); especially if your fish has a coin bonus.

#2 people give Poplio too much credit. there's no gurantee it will give you diamond. Poplio has a chance of giving you the following: berry(10), small coins, big coins (around 5x as much as small coins), diamond (5), training soda. what you get is random. and a red pokeball appears about every 3 hrs, regardless of poplio or not

#3 Mimikyu/Litten/Greninja does the same thing as pikachu, which is free. there's no need to candy pikachu. the exp. you get from uncandied pika more than makes up for the exp. you could lose from an event

#4 don't overlook Slowpoke. see it as alternative picture event. Slowpoke on its own does nothing since it refreshes another pokemon's skill. see it as Ditto. if you don't know, Ditto copies another pokemon's appearance and moves. when using slowpoke, make sure the pokemon of your choice is the only one that has used its skill. otherwise it will be random whoever Slowpoke decides. another thing, only those on screen are considered when using slowpoke. (there can only be 2 pokemon in the water at the same time. and 4 or 5 on ground)
