Overview

Boosts and consumables are temporary power-ups bought with Stars in the Star Shop. They multiply your income, speed up spawning, or instantly create strong holes when you need them.

Because they're temporary, timing matters far more than quantity. A single well-timed 4x cash boost can easily outearn a whole stack of wasted ones used during idle downtime.

Best Boost:2x / 4x cash

Boosts and Consumables List

Every boost and consumable with its effect listed out, so you know exactly what you're buying before spending any Stars.

Stack income boosts during active play for the best returns, since their multiplier only pays off while you're actually merging and earning cash, not while idle.

2x CashDouble your income for a set time
4x CashQuadruple your income for a set time
2x Hole SpawnSpawn holes at double the normal rate

Mystery MeteorDouble spawn rate plus a random reward
Activate cash boosts only when you have strong holes on base - boosting weak early tiers wastes them.

Cash Boosts Explained

The 2x and 4x cash boosts multiply your passive income for a set duration. They're the highest-value consumables because they scale directly with however strong your holes already are at the time.

Use them during active merge sessions when your base is full of high-tier holes. A 4x boost on a Quasar or Omega Hole generates enormous cash in a surprisingly short window of play.

Avoid wasting boosts during downtime - they tick down in real time whether you're playing or not, so active play maximizes their value and idle time simply throws your Stars away.

Spawn Enhancers

Three items that speed up or supercharge your spawning whenever you need holes in a hurry.

Use these to jumpstart merges after starting a fresh run, or to recover quickly after a raid wipes out your base and leaves you empty.

2x Hole Spawn

Doubles your spawn rate to build tiers much faster and refill an empty base after a setback.

Holy Surge

Instantly spawns a level-5 hole, giving you a quick merge jump up the tier list without the usual grinding.

Mystery Meteor

Doubles spawn rate and can crack open for random rewards like extra cash when triggered at the right moment.

Holy Surge is great for recovery - instantly replace a lost hole after a raid.

Using Boosts Efficiently

A routine to maximize boost value, since timing is what truly separates a profitable boost from a completely wasted one.

Never activate a boost during idle time, and stack spawn enhancers with cash boosts for compounded gains during a single focused active session.

1

Fill Your Base

Ensure strong holes are on base before activating a cash boost, so the multiplier has real income to actually multiply.

2

Activate Cash Boost

Turn on 2x or 4x cash during an active merge session when you can play through the whole duration without going idle.

3

Add Spawn Enhancers

Stack 2x hole spawn or Holy Surge on top to build tiers faster while the cash boost is still active.

4

Merge Actively

Keep merging throughout the entire boost window so not a single second of the multiplier goes to waste.

Stacking a cash boost with high-tier holes is the single most profitable combo in the game.

Boost Tips

Quick pointers for getting the most from consumables without wasting your hard-earned Stars on poorly timed uses.

Treat boosts as force-multipliers for active play, not as a way to make idle downtime productive or worthwhile.

  • Buy boosts with Stars earned from the Sun and codes, so you never need to spend Robux on them.
  • Compare temporary boosts against permanent gamepasses to decide which offers better long-term value for your playstyle.
  • Save Holy Surge for raid recovery or endgame rebirth pushes, when an instant level-5 hole matters most.
  • Stack a 4x cash boost with a full base of high-tier holes for the single most profitable combo available in the game.
