The Sun Boss
Everything about the Sun - its massive HP pool, how attacks work, weak points, and the Star reward system.
Overview
The Sun is the central PvE boss in Merge a Black Hole, with over a million HP. It is the main source of Stars in the game - the players who deal the most damage share the reward pool when it is finally defeated.
Because the Sun is a recurring community target rather than a one-time boss, every player gets repeated chances to climb the damage leaderboard and earn a meaningful slice of the Star pool.
Sun Boss Stats
Key facts about the Sun target, starting with its enormous HP pool that makes every defeat a shared community effort rather than a solo kill.
Its huge HP means it takes many attackers working together to bring it down, so your goal is to claim the largest possible share of the damage, not to finish it alone.
Because the HP is so high, even very strong players only contribute a small fraction per launch, which is why consistent attendance matters far more than sporadic bursts.
| Stat | Value |
|---|---|
| HP | 1,000,000+ |
| Reward | Stars (by damage share) |
| Attack Cooldown | ~1 minute |
| Weak Points | Yes - bonus damage |
How Sun Attacks Work
To attack the Sun, launch your black holes at it. Each launch deals damage based on your holes' power, then triggers a short cooldown of about a minute before you can attack again.
Because the Sun has over a million HP, it takes many attackers working together to bring it down over time. The leaderboard tracks total damage dealt by each player, and your final reward is proportional to your position.
Maximize your share by using your strongest late-tier holes and hitting weak points whenever they appear, stacking every available multiplier into each and every launch.
Maximizing Sun Damage
Three core factors that boost your Sun damage share, each of which you can independently improve to climb the leaderboard over time.
Hole Power
Stronger holes deal more base damage per launch, raising your floor damage every single time you attack the Sun.
Weak Points
Hit weak points for big bonus damage, which is the single largest multiplier available in any Sun fight.
Boosts
Equip a Wormhole for extra attack damage that stacks on top of your already strong holes and weak-point hits.
Sun Attack Routine
A repeatable routine for Sun combat, where each launch is timed for maximum effect and your attacking holes stay protected so they survive to deal damage.
Consistency is the key to topping the leaderboard, since regular well-timed launches with weak-point hits reliably add up to top spots over a full fight.
Ready Strong Holes
Have your best holes ready to launch before the fight heats up, so every cooldown window is used on maximum damage.
Launch at the Sun
Send holes at the Sun and watch closely for weak points appearing that you can immediately exploit.
Respect Cooldown
Wait out the roughly one-minute cooldown between attacks, using the time to merge or defend rather than idle.
Claim Stars
Earn Stars based on your damage share when the Sun falls, then reinvest them to grow stronger for next time.
Sun Boss Tips
Quick pointers for better Sun performance, focused on the high-impact habits that separate leaderboard-toppers from the rest of the attackers.
The Sun resets and respawns regularly, so the fight is a recurring opportunity rather than a one-time event - building a strong routine pays off every single cycle.
- Climb the tier list steadily to deal more Sun damage over time, since base hole power is the foundation of every successful leaderboard run.
- Read the full Sun strategy guide for advanced tactics that squeeze extra damage out of every single launch window.
- Protect your attacking holes with best-hole protection so raiders cannot steal the exact holes you rely on for your damage share.
