The Valentine’s update in Break A Lucky Block added a limited-time aerial boss called Heartbreaker Sammy. Unlike regular Lucky Block grinding, this event shifts the action into the sky and guarantees special mutated rewards once cleared. Alongside the boss fight, the update also adds a Sacrifice Machine that lets players exchange Brainrots for high-rarity blocks. If you want guaranteed Heartbroken Mutations and exclusive Sacrifice rewards, here’s everything you need to know.
How to Beat Heartbreaker Sammy in Break A Lucky Block

Heartbreaker Sammy spawns above the Lucky Block area. The boss appears as a dark angel with violet and black effects, battling a Cupid Sammy mid-air. The boss has 150 HP. To fight the boss, jump into the air. Your character will automatically begin floating.
While airborne, you must time your swings and hit Heartbreaker Sammy using your pickaxe. Each hit deals exactly 1 HP damage regardless of your pickaxe rarity. This means you must land 150 successful hits to defeat the boss.
Since everyone deals identical damage, you need to be careful about positioning and timing. Follow the boss’s movement pattern and avoid wasting swings. If multiple players are attacking, the fight ends much faster. Once defeated, a mini-event begins immediately.
Heartbreaker Sammy - Boss Rewards
Defeating Heartbreaker Sammy triggers a temporary global mutation event. During this mini-event, every Lucky Block broken will guarantee a Brainrot with the Heartbroken Mutation. This is the most efficient time to farm Heartbroken variants because the mutation is guaranteed rather than random.
If you are looking to collect Brainrots with this trait, save your blocks and open them during the event window. The boss itself does not drop direct loot. Instead, the value comes from the mutation guarantee event that follows.
