Overview

The Star Shop is where you spend Stars on powerful boosts and items, including cash multipliers, hole protection, and spawn enhancers. Stars come mainly from attacking the Sun and from redeeming free codes, so steady Sun damage funds the whole shop.

Because Stars are earned through combat rather than bought with Robux, the shop is the primary way free-to-play players access powerful temporary upgrades and protection that rival what paying players enjoy.

Star Shop Items

Key items available in the Star Shop and exactly what each one does, so you can compare value per Star before committing your hard-earned currency to a purchase.

Prioritize the items at the top of the list for the best value per Star, especially early on when cash and hole power are your main bottlenecks.

Late-game players shift toward spawn items and protection, since the relative value of each category changes as your power and the threats you face evolve over time.

Cash boosts are the best early purchase - they multiply your passive income directly and accelerate every other upgrade you make afterward.

What to Buy First

New players should buy 2x cash boosts first, since they multiply income during active play and accelerate every other upgrade, turning a slow early game into a fast snowball of growth.

Once you hold valuable holes, shift spending to best-hole protection - a single raided hole costs far more than the protection price, so it pays for itself the moment it blocks one attack.

Late game, Wormhole boosts and Holy Surge become attractive for pushing Sun damage and fast merges, helping you climb the damage leaderboard and reach the powerful late tiers quickly.

Star Shop Categories

Three broad categories of items in the shop, each suited to a different stage of your progression and a different immediate goal or bottleneck.

Boosts

Cash and spawn multipliers that supercharge active sessions - see the boosts guide for stacking tips and timing.

Protection

Guard your best hole for 24 hours with protection, essential once you hold late-tier holes that raiders would love to steal.

Spawn Items

Holy Surge and meteors spawn strong holes instantly, letting you skip grinding and jump straight up the tier list when you can afford them.

Don't hoard Stars - spending them on boosts compounds your progress far more than saving, since idle Stars earn nothing while active boosts multiply everything.

Recommended Purchase Order

A sensible order for spending Stars across a run, with each purchase addressing your current bottleneck so every Star delivers maximum value.

Re-evaluate your priorities after each rebirth, since your needs shift as your power level and the threats you face change over time.

1

Cash Boosts

Buy 2x cash early to multiply your income during the phase when cash is the main thing holding back your hole tiers.

2

Spawn Boost

Add 2x hole spawn to build tiers faster, giving your auto-merge more raw material to combine into stronger attackers.

3

Hole Protection

Protect your most valuable holes with protection before they become tempting raid targets for stronger players nearby.

4

Push Items

Use Holy Surge and Wormholes for endgame pushes, smashing through plateaus and chasing top Sun damage shares.

Protection becomes essential once you hold late tiers - buy it before you need it, because a single raid can erase hours of merging.

Star Shop Tips

Quick pointers for smart Star spending and squeezing the most long-term value out of every reward you earn from the Sun and from codes.

The shop rotates in usefulness as you progress, so re-check the available items after major milestones like reaching a new late tier or a rebirth.

  • Earn Stars via the Stars guide and free codes - they fund the entire shop without spending any real money.
  • Compare shop options against gamepasses for permanent alternatives that never expire and keep paying off forever.
  • Time your boosts around your most active merge sessions so the multiplier is active when you are actually playing.
