Solstice Week has officially begun in Pokémon GO. Until June 20, hot Fire-type Pokémon such as Charmander, Typhlosion, Houndour and Charizard, as well as chilly Ice-type Pokémon such as Sneasel and Lapras are appearing more frequently. Plus, you can get massive XP boosts when you accomplish certain actions in your game. For example, catching a Pokémon with a Curveball throw will reward you 30 XP instead of the usual 10 XP. Finally, Lucky Eggs are 50 percent off in the in-game shop all week long.
