After reaching level 9 in Pokemon Go, players are now able to have access to the Lucky Eggs. These Lucky Eggs grant double experience points for thirty minutes when activated. This is the best time to grind to fasten increase of the trainer's level. Players can obtain Lucky Eggs starting at level nine as a reward or they can purchase it through the game's store by using Pokemon Coins. As you activate this egg, like the Incense, timer will start ticking and will continue to run even if you are playing or not. So, using it strategically will help you maximize its effect.
According to MobiPicker, in order to make the most of the Lucky Egg's effect, you need to have these several items on your checklist: multiple Pokemon ready to evolve, a whole bunch of Stardust, Incense and lots of Pokeballs. When you are ready, activate the lucky egg and start doing your thing. It is even better if you will also install Lure Modules or Incense while the Lucky Egg's effect is on-going. A massive evolution from several Pidgeys, Rattatas or any other Pokemon, catching Pokemon, visiting through Pokestops and Powering up your captured Pokemon will give you a massive amount of experience points.
According to Heavy, Lucky Egg will grant trainers 200 experience points for every captured Pokemon, 1000 XP for evolving a Pokemon and an impeccable 2000 XP for evolving a Pokemon into something that have not yet registered to the Pokedex. Lucky Egg will also grant 1,200 XP for every newly captured Pokemon for the first time. Based on some reports, players can have up to 60 evolutions per 30 minute span. If you can achieve this 60 evolutions, a massive 60,000 XP will get into your way easily with just one Lucky Egg. Hoarding those Pidgeys, Rattatas and other commonly encountered Pokemon does make sense after all.
If you want to do the Lucky Egg trick in the earlier game, you can purchase it through the in game store with 80 coins each, others are 8 for 500 and 25 for 1,250 coins. That will cost about $0.99, $4.99 and $9.99 correspondingly.
