Complete tasks each day to earn tickets. The more tickets you get, the better your chances of winning one of these awesome prize packs! — In game description
”
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. It is unavailable in Bloons TD 6+, Bloons TD 6 NETFLIX, and the Chinese version of the game, and there are restrictions on which players are allowed to participate per the terms and conditions.
A player can only participate in a Sweepstakes Event if:
They are located in Australia,[fn 1] Austria, Brazil, Canada, Czechia, Denmark, Finland, France, Germany, Hungary, Ireland, Japan, Luxembourg, Macao, Mexico, the Netherlands, New Zealand, Norway,[fn 1] Peru, the Philippines,[fn 1] Poland, Singapore, South Africa, South Korea,[fn 1] Spain, Sweden, Switzerland, Taiwan, the United Kingdom, or the United States.[fn 2][1]
They are not playing on an account flagged for cheating.
Players found using multiple accounts are disqualified.[1]
Tickets
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).

Tasks
One set of five challenges becomes unlockable every day at 23:00 UTC after the event starts but each set needs to be manually unlocked by the player so the countdown for the next day starts. If they skip a day(s), the amount of available tasks will be delayed by the number of missing days in comparison to players who played daily. This means players who start the event late or skip several days may not be able to get access to all available tasks before the event ends. 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.

Notes
Beat Maps
Challenges that require playing on a specific difficulty can be done on any game mode of that difficulty (e.g. Reverse will count for Medium and CHIMPS for Hard). Daily Challenges do not count.
Daily Challenges
Daily Challenges, Advanced Challenges, and Co-op Daily Challenges all count. Replaying a completed challenge does not count.
Fight a Boss
Only counts if played in single player, not Co-op. Can be done on Normal or Elite in Boss Challenge or a Boss Bloon Event. Beating later tiers also counts for previous tiers.
These challenges only count blue MOABs, not MOAB-Class Bloons, despite what the name implies. Daily Challenges and Quests do not count.
Take Part in an Event
Scores can be done on the same Event, and the score doesn't need to be better than the previous one. For Boss Bloon Events each Tier in Ranked Mode counts as a score submission. Replaying a previously completed Odyssey also counts.
Try a New Hero!
Only counts if the player places the Hero. Starting a game with a Hero Skin that was already used, then switching to a different skin before completing the game, still counts towards challenges that require using different Heroes and skins.
Notes:
Playing in Legends do not count towards completing taks.
