Events

Clicker Events
Up to this point all clicker events have had a buy in cost for F2P users. 2000-6000 Gems on day one to increasing click power (for normal players) or 900-1200 gems on stamina boosts at the end of the event for players that do not sleep or can create fool proof clicking macros.

In all cases, the later you get started the more it will cost you. After day 3, making up ground becomes very expensive.

Lucky Wheel
Do not spend your quest tokens until you have enough to be given the main prize (normally 25 tokens). There is a chance you will get the prize from the free daily. If you do, it will reset the counter that counts down to the prize.

It is best to save up and spend near the end of the event.

Ancient Vault
Expect to use 20-35 keys for each floor. Always leave as soon as possible.

For vault quests do not level an artifact with more than one fodder piece at a time. It will count as a single level up regardless of how many pieces you use.

Carnival
Carnival requires around 80 tickets to fully complete. Its recommended to have 10+ tickets on hand when the event starts.
