Idle Progression in MergeCiv: Offline Earnings, Boosts and Daily Routine
MergeCiv is generous to players who step away — once you understand what the game simulates while you are gone. Here is how offline earnings are calculated, how the Speed Boost turns time away into a 10x multiplier, and how to run a daily routine that wastes none of it.
How Offline Earnings Are Calculated
The game starts counting offline time once you have been away for more than 10 seconds, and it stops counting at 12 hours. Two check-ins per day capture the full 24 hours of offline payouts.
While you are away, the following keep ticking: yields from resource tiles worked by an adjacent settlement, flat passive income from the Agricultural, Forestry and Mining Tradition legacy upgrades, Gold from Tribute, Taxes and artifacts like the Interest Accumulator, Mana from the Apprentice, Knowledge from your Citadel, Culture from the Printing Press artifact and Fiction-powered Libraries, and Metal refined by active Forges (as long as your Ore stockpile can feed them).
Spoiler: Late-Game Offline Compounding (The Evening Paper & Conquest Valor)
One nuance for Interest Accumulator owners: out of the box, offline interest is a flat approximation — it pays out on the Gold you had when you left, not on the Gold piling up while you are gone. The Evening Paper Knowledge upgrade (400K Knowledge, one purchase, kept through Resettlements and Ascensions) removes that approximation: with it, offline and Boost earnings compound every tick exactly like live play, so your Tribute and Taxes earn interest of their own the moment they arrive.
In Conquest, ground is only captured while The March is on screen, but when you step away for more than a minute your camp pays offline Valor at 10% of your best 5-minute live Valor rate ever recorded (for up to 8 hours per absence), and Boost claims grant the same fraction.
Notice the qualifier: worked tiles. A Wheat Field with no settlement beside it produces nothing, online or offline. Before you close the app, make sure your best resource tiles sit inside a settlement's work pattern — the Beginner's Guide covers how those patterns grow from Tier 1 Villager to Tier 4 Castle.
Two safety rails are built in. Net Food cannot go negative offline, so your population will not eat your stores down to zero overnight. And board automation is paused while you are away: the Scout spawns nothing and the Apprentice merges nothing. The grid you leave is the grid you return to, so finish your merges before you log off.
The one thing the game will not protect you from is storage. Production that overflows a full cap is lost, and twelve hours is a long time to be capped. Merge your Stockpiles up a tier, buy Grain Silos levels (+100% Food storage each, up to five), and consider the Ritual of Capacity before any long absence.
The Speed Boost: Banked Time at Up to 10x
Claiming your offline earnings also banks Speed Boost time: one effective second for every real second you were away, capped at 14,400 seconds — four hours of bank. The multiplier you play at follows a linear formula: 1 + 9 × (banked seconds ÷ 14,400). A full bank means 10x, and the multiplier decays as the bank drains, which the UI shows live ("7.3x" and falling).
Any absence of four hours or more sends you back at a full 10x. Sleeping eight hours banks the same boost as sleeping four — the extra hours still pay offline earnings (up to the 12-hour cap) but add nothing to the boost bank. Offline-earned boost caps at 14,400 seconds, while boost from daily claims can stack past that ceiling.
Because the multiplier is highest the moment you claim, front-load your active play into that window: scouting, merging, and buying upgrades at 10x compounds your board much faster than letting the boost drain idle.
Daily Boost Claims: Four Extra Hours, Every Day
The Boost modal holds up to four boost charges and refills one every six hours, so a day's refill is four claims: one free daily boost, then up to three more — and the free one, which still spends a charge, must be claimed before the others unlock. On iOS each of the others costs a rewarded video ad; the web and Android show no ads, so there they unlock with the Founder's Pack. Each claim instantly grants one full hour of non-Mana production at your current rates, plus 3,600 seconds of boost bank; Founders also get one bonus second for every Founder worldwide. Mana and Mana Syphon crystals come from the accelerated live period instead of also being paid in the instant reward. Founder's Pack owners skip the ads entirely.
A full set of four claims is four instant hours of production and four more hours of boost time on top of whatever your offline return banked. Because the instant hour is capped by storage, always spend down your resources between claims rather than claiming all four back-to-back into full Stockpiles.
A Worked Example: The Two-Session Day
Morning (10 minutes)
- Open the game after eight hours away. Claim offline earnings — all eight hours pay out, and the Speed Boost bank fills to 14,400 seconds (10x speed).
- Claim the free daily boost. Spend the instant hour's resources immediately — upgrades, a grid expansion, Villager spawns — so storage has headroom again.
- Claim the next charge, spend, and repeat for the remaining charges. Claim-spend-claim beats claim-claim-claim every time, because each hour of production needs empty caps to land in.
- Play actively while the multiplier is above ~5x: scout aggressively, merge pairs, and let the Apprentice clean up.
Evening (5 minutes)
- Check in before the 12-hour offline cap expires on the day's second stretch. Claim, merge, and tidy the grid so every key resource tile is worked.
- Confirm Stockpiles have room for the night, then close the app. Two sessions like this capture a full 24 hours of earnings.
Active vs Idle: How They Fit Together
Scout spawns, Apprentice merges, and Conquest road captures only happen while the game is open, so tier and landmark progression are active-play activities. Meanwhile, passive income — worked tiles, Tradition legacies, Tribute from Resettlements, Taxes, Knowledge from the Citadel, and offline Valor — runs around the clock. Build for storage and passive income before logging off, then cash in your banked 10x Speed Boost with focused active bursts.
The Apprentice and Mana While You're Away
By default the Apprentice only generates Mana while resting, but the MANA Test upgrade (5,000 Gold + 100 Mana) lets it channel Mana continuously while working. Once you unlock Mana Syphon, any Mana that overflows your cap (including during live boosted play) converts into Magic Crystal charge at a 10:1 ratio — see Chapter 5: Ascension & Magic for the full crystal loop.
