Planet clicker strategy guide
Idle games look simple, but a little planning makes the numbers climb a lot faster. Here is how to get the most out of PlanetIdle.
Early game: buy the cheapest thing, always
For the first few minutes, the single best rule is to spend your Stardust as soon as you can afford the next building or upgrade. Idle production compounds — Stardust you bank earns nothing, but Stardust spent on a structure earns forever. Don't hoard.
Upgrades beat raw buildings
Channel and building multipliers are almost always worth buying immediately. A "×2" upgrade doubles a whole category of income for a flat one-time cost, which quickly outpaces buying one more of an expensive structure. When an upgrade lights up, grab it.
Use synergy upgrades
Some upgrades are synergies: they make one building stronger for every copy you own of another. "Atmosphere–Ocean Coupling" boosts your Ocean Seeders by a few percent for each Atmosphere Spire, so the more of the source building you stack, the bigger the payoff. Buy the source building heavily once you own the synergy.
Chase the milestone stars (★)
Every building hits a milestone at 10, 25, 50 and 100 owned — each permanently makes that building produce ×1.5 more (so a building at 100 produces about ×5). The stars on each row show how close you are. It's often worth buying a few extra of a cheap building to push it over the next milestone, because the ×1.5 applies to all of them at once. Use the ×10 / ×100 buy buttons to reach milestones quickly.
Catch the comets ☄️
Every minute or two a comet streaks across the screen for about 13 seconds. Always tap it — it gives one of two rewards at random:
- Windfall — an instant lump of Stardust (scales with your bank and income).
- Supernova — ×7 production for 15 seconds. This is the single biggest swing in the game.
Pro move: channel furiously during a Supernova, since your click power is multiplied too, and try to spend it when your Stardust-per-second is already high.
When should I make a Galactic Leap?
A Leap (prestige) collapses your whole world into a singularity for Starcore Shards, which permanently boost all future production. The boost has diminishing returns — it grows with the square root of your total Shards, so your first Shard alone adds about +40% while each later one adds a little less. A common guideline: leap when doing so would increase your permanent multiplier by at least 50–100% — i.e. when your pending Shards are worth roughly as much as what you have already built. After a Leap your permanent multiplier makes the next world much faster, so you blast back to where you were and push further. Note that later worlds also raise building costs (a New Game+ challenge), so lean on upgrades, comets and channeling skill to keep up.
Use offline progress
Your world keeps producing while the tab is closed, up to 8 hours. Before a long break, get your Stardust-per-second as high as you can — you'll come back to a pile of Stardust and a "welcome back" bonus.
