Boss Bloon Event: Difference between revisions

'''Boss Bloon Events''', also called '''Boss Events''', are weekly events in ''[[Bloons TD 6]]'' introduced in [[Bloons TD 6 v27.0|version 27.0]] where players encounter [[Boss Bloon]]s in a modified version of a [[Boss Challenge]]. It was introduced alongside the Boss Bloons' weakness, the [[Paragon|Paragons]]. In each event, one of the Boss Bloons is selected to appear on a [[map]], possibly with some [[Challenge rule|challenge modifiers]] such as tower and hero restrictions. Victory is achieved in a Boss Bloon Event by defeating all five tiers of the boss before round 140 starts. The Elite version of the boss may not be attempted in single-player until tier 5 of the Normal boss is defeated.

The Boss Bloon Event usually runs weekly, starting Saturday at 02:00:00 UTC and ending Thursday at 03:00:00 UTC. There are sometimes exceptions to this schedule: for example, events typically end earlier right before a major update. Boss Bloon Events generally cycle between the six available bosses in the following order: [[Bloonarius (BTD6)|Bloonarius]], [[Lych (BTD6)|Lych]], [[Vortex (BTD6)|Vortex]], [[Dreadbloon (BTD6)|Dreadbloon]], [[Phayze]], and [[Blastapopoulos (BTD6)|Blastapopoulos]]. Directly after an update that releases a new boss, these events feature the new boss for 4 weeks before returning to the regular order.

Since [[Bloons TD 6 v31.0|version 31.0]], during the final hour of the event, players on Ranked Mode cannot start a new run, and those who are in the middle of a game will not be able to resume if they exit the game. This was done with the intention of preventing scores from being submitted past the ending time of the event.

The general gameplay is the same as in Boss Challenge with the Tier 1 boss appearing on Round 40, and the successive tiers appear every 20 rounds until the final Tier 5 boss spawns on Round 120. A banner will be visible at the top of the screen indicating the number of rounds remaining until the boss appears, and while it is on the screen, the banner is replaced by the boss's health bar. Players receive rewards after beating each tier, but if the boss reaches the exit or is not beaten after 20 rounds since spawning, a defeat will occur even if no lives are lost. While the boss is on the screen, there are no breaks between rounds even if Auto Start is disabled. On most weeks the roundset will be the same as in Boss Challenge for the corresponding Boss, but custom rounds have been used in the past and are set sever-side.

Before starting a game, players may check a box in the lower left part of the screen to play in Ranked Mode, in which players compete to place as high as possible on a leaderboard for additional prizes. This mode disables Insta Monkeys, Powers and in-app purchases (such as [[Double Cash Mode (BTD6)|Double Cash]] or [[Fast Track Mode|Fast Track]]) to prevent pay-to-win scenarios. Everything else regarding to the event (Boss, Map, modifiers and restrictions) is the same as non-ranked mode.

There is also a penalty timer (shown in red below the boss banner/health bar) that penalizes players for taking too long to beat non-boss rounds. Every round, <code>10 + Round Number × 0.25</code> seconds after the last Bloon of a round enters the screen, a timer begins to count up until all Bloons from that round are popped.  At the end of the game, all accumulated time in the penalty timer is added to the regular Boss timer. The cooldown of cash-generating abilities is paused while the penalty timer is active, even in non-Ranked mode (where the timer does not appear), to prevent abuse and weaken strategies based on income-generating abilities like [[IMF Loan (BTD6)|IMF Loan]] or [[Jungle's Bounty (BTD6)|Jungle's Bounty]].

Every week, one of the three scoring types is selected for Normal and Elite and all players who defeat the boss will be ranked according to it. The scores for Normal and Elite bosses are independent from each other, and since [[Bloons TD 6 v44.0|version 44.0]], they can have a different scoring type on the same week. Regardless of the type used, the timer described above will appear because it is used as the tie-breaker in Least Cash and Least Tiers rankings.

The most important advice for defeating Bosses, especially Elite versions, is to generate additional [[Cash|income]] (a.k.a. farming) and start doing so as early as possible. Normal Bosses can sometimes be beaten without additional income and a proper defense strategy, but Elite Bosses are simply impossible without farming. [[Benjamin (BTD6)|Benjamin]] and [[Geraldo (BTD6)|Geraldo]] are the most used [[Hero]]es in Boss Bloon Events thanks to having methods of generating extra income that can be used to accelerate early game farms. Other heroes with an early game carry or buffing potential are used when both of these heroes are banned.

More details for the gameplay between tiers can be found in the main Strategy article. Strategies to defeat the boss itself are found in the strategy page for each Boss Bloon: [[Strategy:Bloonarius (BTD6)|Bloonarius]], [[Strategy:Lych|Lych]], [[Strategy:Vortex (BTD6)|Vortex]], [[Strategy:Dreadbloon (BTD6)|Dreadbloon]], [[Strategy:Phayze|Phayze]] and [[Strategy:Blastapopoulos (BTD6)|Blastapopoulos]].
