SimpleIdle: A Beginner's Guide to Your First Hour

You generate Units. Units buy Producers. Producers generate more Units. After a while, you reset everything and start over with a permanent multiplier called Remnants. That is the whole game, and the first hour is about getting comfortable with it.

This guide assumes nothing. If you have played Cookie Clicker or Antimatter Dimensions, you can skim. If this is your first idle game, every section matters.

The shortest possible explanation

The first recursion lands somewhere between four and eight hours of play. Most of that is automated. You are mostly making small decisions about what to buy next.

Your first ten minutes

The game opens on the Generate tab. You will see one button: a Starter, costing 10 Units. You start with 0 Units, so the button is dimmed. Click anywhere on the Starter card to buy your first one for free (the game grants you the opening purchase).

Now wait. The Starter produces 1 Unit per second. Watch the counter climb. When you have enough, buy a second Starter. Then a third. The cost goes up by 5% per copy in Tier 1, so the curve is gentle.

Once you own 10 Starters, a Duplicator unlocks below it. The Duplicator costs more but produces more. Buy one. Keep buying Starters too, because Tier 1 producers feed each other through a mechanic called Quantity Resonance: the more copies you own of a producer, the more every producer benefits.

Repeat this pattern through the Tier 1 chain: Starter → Duplicator → Triplicator → Shifter → Streamer → Connector → Grouper → Solidifier → Arranger → Structurer. Each new producer unlocks at 10 copies of the previous one. By minute ten you should be working on Triplicator or Shifter.

One rule for this stage: if a new producer is available, buy one. The first copy of a higher-step producer almost always out-earns the next copy of a lower one.

The first hour

Around minute fifteen, two things happen. The Evolve tab lights up, and the first milestone bonus fires when one of your producers hits 10 copies.

Improvements (the Evolve tab)

Press E or click Evolve. You'll see Improvements, which are SimpleIdle's upgrades. Each one is a small, permanent multiplier on production, tick rate, synergy, or some specialized mechanic. The first three you should reach for, roughly in order:

1. Minor Production Boost (+25% to all production)
2. Basic Tick Boost (+25% to how often production fires)
3. Basic Synergy (boosts the bonus you get from owning multiple tiers)

Improvements cost Units that could otherwise buy producers. Don't agonize over the trade. As a rule, if an Improvement costs less than 10× your current Unit pile, buy it. If it costs 100× more, ignore it for now.

Milestones

When a producer hits 10 copies, it gets a permanent ×2 multiplier. At 25 copies, ×3. At 50, ×4. The ladder continues: 75, 100, 150, 200, 250, 300, and so on. The takeaway: copies are not just for unlocking the next producer. Every producer you keep buying eventually crosses another milestone and pays for itself again.

Tier 2 and beyond

Once you finish Tier 1 (10 Structurers), Tier 2 unlocks. These are Basic producers (Cycler, Expander, Circulator…). They cost more, produce far more, and have a per-copy cost growth of 15% instead of Tier 1's 5%. The pace of buying slows; the size of each purchase grows.

By the end of hour one, you will probably be partway through Tier 2 or Tier 3. That's normal. The first recursion is still hours away.

What the four screens do

Stats and Achievements live in the top-right utility row. You can leave them alone for now.

Offline progression

Close the tab and come back later. When you return, SimpleIdle shows a Welcome Back modal that catches you up on what you missed. Two things to know:

1. The first five minutes of a fresh save don't catch up. This is intentional. The game wants you to actually play before it starts banking your absence.
2. The default offline cap is 30 minutes at 50% efficiency. If you're gone for two hours, you get credit for 30 minutes of half-rate production. Improvements later raise both the cap and the efficiency.

Translation: SimpleIdle rewards you for checking in, not for grinding. Five minutes here, ten minutes there, will outpace one long session every time.

The decision you're building toward

Once your Lifetime Units hits 1,000,000,000 (one billion), the Transcend tab becomes active. You can wipe your progress and start over with Remnants.

At exactly 1B lifetime, you get 27 Remnants. Every Remnant adds a small permanent multiplier to all future production: 27 of them stacks to about ×4.2. The numbers grow fast: at 1e10 (10B) lifetime you'd get 46 Remnants and a ×6.3 multiplier; at 1e12 (1T), 99 Remnants and ×11.5.

The honest answer to "when should I first recurse?" is: somewhere between 1× and 100× the minimum. Recursing the moment you're allowed is fine. Pushing to 10B or 100B before recursing gives you a bigger first jump, but you spend a lot of real time for diminishing returns. There is a whole article on this question, but a defensible default is: recurse the first time when you can do it without resentment, ideally when you've stopped making meaningful progress without it.

After the first recursion, you keep your unlocked Improvements (you don't keep their ranks, but they stay unlocked). One Improvement called Recursion Memory even keeps a few Tier 1 copies of each producer through the reset, so the second run is much faster than the first.

Three rules for new players

1. Buy the new thing. Whenever a new producer or Improvement unlocks, buy one. The first copy of anything new is almost always the best Unit-per-cost purchase available.
2. Don't grind for milestones. If you're 4 copies away from a 50-milestone and the next purchase takes 20 minutes, move on. The milestones come back.
3. Don't optimize the first run. You will recurse and reset most of what you optimized. Spend the first run learning the systems, not maximizing them.

What to do next

When you're comfortable with the loop and have Tier 2 and Tier 3 producers running, two articles will help most:

• When Should I First Recurse in SimpleIdle?: the math for the decision above.
• SimpleIdle Upgrade Priority: A Math-Backed Order: which Improvements to chase, by stage.

If anything in the UI confuses you, the SURPLUS chip explainer covers the small green badge that appears on producers once you've over-bought a tier.

Frequently asked

How long is the first hour, really? Most new players land somewhere in mid-Tier-2 or early Tier 3 by the 60-minute mark. You'll have a few Improvements ranked up and your first milestone bonuses firing. The first recursion is usually 4–8 hours away.

Do I need to keep the tab open? No. SimpleIdle credits you for offline time up to 30 minutes (extendable). You can close the tab, work for an hour, and come back to a Welcome Back modal that catches you up.

Should I buy producers in bulk? Yes, once you have enough Units. There's a "buy max" option that reads your current pile and grabs the most copies you can afford in one click. Use it freely. The Bulk Discount Improvement makes this even better.

What if I mess up? You can't. There is no "wrong" first run. Recursing wipes your progress on purpose, and even a poorly-played first hour gives you the same first-recursion threshold as a perfectly optimized one.

Where do I save? Your save lives in browser localStorage and writes automatically. Closing the tab is safe. If you want to back it up or move it to another browser, the save file guide walks through export and import.
