When to Prestige: Resets in Idle Games Explained
Every idle game eventually asks you to throw your progress away. The reset goes by many names, such as prestige, rebirth, ascension or new game plus, but the deal is always the same. You give up what you have built, you keep a permanent bonus, and the next run is faster. Deciding when to take that deal is the biggest strategic choice in the genre.
The three games on Idle Center handle prestige in three very different ways. This guide explains how each one works, what it really rewards, and when to reset.
The general rule
A reset is worth it when the permanent bonus will save you more time on the next run than you would gain by continuing this one. In practice, two signals tell you that you are there:
- Your next purchase is far away. If the next upgrade or unlock is half an hour of waiting away, but a fresh run would race back to this point in a fraction of that, it is time.
- The reward has stopped growing quickly. Prestige rewards usually grow slower and slower the longer you play, often with a square root. Once an extra ten minutes adds only a sliver to the reward, take it.
Some games make the decision for you by fixing when you can reset. Primordial Tap is one of them.
Primordial Tap: Extinction
In Primordial Tap, prestige is the end of the story. Extinction becomes available only after you reach the final stage, Stage 18, and push total energy to ten times its threshold. There is no early reset to time, so the question is not when but how well.
Extinction pays out Evolutionary Echoes, and the formula rewards the quality of the run, not its size:
| Part of the reward | Echoes |
|---|---|
| Reaching Extinction | 3 |
| Stages climbed (0.1 for each stage after the first) | 1.7 |
| Answering every trivia gate correctly the first time | +2 |
| Finishing the run in under 200 / 300 / 420 minutes | +2 / +1 / +0.5 |
The total is rounded down. A careful run that finishes in about three hours with no wrong answers earns 8 Echoes, while a relaxed six-and-a-half-hour run with a couple of mistakes earns 5. Time the game is closed does not count against your run time, so the speed bonus measures your play, not your calendar.
What to do with them: start with Tier 1 Genetic Memory. These upgrades cost one or two Echoes per level and boost passive income, tap power or auto-taps immediately. Five levels in Tier 1 open Tier 2, where Accelerated Growth makes every upgrade cheaper. The upgrade list has every Genetic Memory upgrade with its cost and effect.
IdleCenter: Studio Legacy
IdleCenter gives you a genuine timing decision. Once you have researched Legacy and your studio has earned $5,000,000 in the current run, you can found a new studio at any time. You lose cash, ideas, staff, your catalog and per-run research. You keep your Codex of discovered combos, permanent research such as Offline Progress, and Reputation.
Reputation is the square root of what you earned ÷ 15,000, and every point adds 3% income to every later studio. The square root is the key. Reaching the minimum gives 18 points (+54%), and doubling your earnings to $10,000,000 only raises that to 25 (+75%). The first $5,000,000 is worth much more than the second.
When to reset: your first Legacy usually becomes available after 60 to 90 minutes. Taking it soon after is a good default, because the second run is several times faster and the permanent research that opens after Legacy (Codex Bonuses, Fan Network, Studio Legend) keeps paying off. Stay longer only while your income is still climbing steeply, for example right after a big hire milestone. When income flattens out, found the next studio.
One practical tip: your Codex survives Legacy, but the run's research does not. Releasing a few combos you have not tried before resetting fills in the Codex for every future studio. The research tree shows which nodes are kept.
Realm Forge: the exile choice
Realm Forge treats prestige as an ending. After the Village, the Kingdom and the Empire, the final confrontation offers you a choice. Accept Exile adds a prestige level: each level grants a permanent 50% bonus to forge production and five starting Renown in every later run. Reject restarts without adding a level. Prestige you already earned is kept either way.
Because there is only one moment to decide, the choice is simple: accept, unless you specifically want a fresh run without the bonus. The five starting Renown matter more than they look. Renown funds Scholars and Libraries, and the Kingdom needs 45 Renown to rise, so a head start shortens the Village phase noticeably. The economy page lists every Renown milestone.
Three questions before any reset
- What exactly do I keep? Read the confirmation screen. Permanent research, codices and achievements are often kept, while currencies and buildings are not.
- Is anything cheap still worth buying first? If something carries over, such as a codex entry or a permanent node, buy it before you reset, not after.
- Is my save backed up? All Idle Center games save in your browser. IdleCenter also has an export code you can copy before a big decision.
