The Sweepstakes Event is an event in Bloons TD 6. It was added to the game files in version 49.0, but it was not publicly revealed until version 49.3. The objective of the event is to complete challenges to earn tickets in order to enter the sweepstakes. A new challenge unlocks on each day, and each challenge has multiple milestones to reach to earn more tickets. The more tickets a player has, the more likely they are to win.
Players with accounts flagged for cheating cannot participate in the event. Players who are found to use multiple accounts for this event will be disqualified.[1] The Sweepstakes event is unavailable on Bloons TD 6 NETFLIX and Bloons TD 6+.
There are two ways to earn tickets: participating in the challenges and using referral codes. Each participant is assigned a unique referral code that other participants can enter (a participant cannot redeem their own code). A player can earn a maximum of 150 tickets.

Tasks
One set of five challenges becomes available on each of the first seven days of the event. If multiple challenges have the same scoring requirement, then progress goes towards all of them at the same time (for example, popping Bloons counts towards all five "Pop Bloons" challenges). If the player completes a challenge before any previous challenges in the same set, they won't be able to claim the tickets for it until all previous challenges in the set are completed as well.

Beat a weekly Odyssey made by Ninja Kiwi in Hard difficulty
Scores can be done on the same Event, and the score doesn't need to be better than the previous one. Replaying a previously completed Odyssey also counts.
