Major update

Patch 1.1: A Tale of Two Civs

CivIdle · published 8 Jan 2026, 11:03 UTC · build 21421763

All newsPlayers around this dateRead on Steam

First of all, happy new year, everyone! I am happy to present Patch 1.1, our first post-1.0 patch. This patch features two new civilizations, and new content is available at no additional cost. A big thank you to all beta players who have helped with testing and giving feedback.

Also, this year's Lunar New Year (formally known as Year of the Snake) special wonder has been updated (available from 2.10 ~ 2.24).

In the draft patch notes, I've talked about the plans after 1.1 so give that a read if you haven't. Now, enjoy the patch notes for 1.1:

New Civ: Canadian (50x50)

Unique Buildings


AI Lab (Artificial Intelligence): Internet x2 + Supercomputer x4 + Radio x2 => CivGPT x2


Chateau Frontenac (Combustion): This wonder can be upgraded. Each time it levels up, three random buildings from the current age are drawn. Select one of them to receive +1 Building Level Boost (cannot be changed once selected)


Habitat 67 (Artificial Intelligence): This wonder can be upgraded and each level provides +1 Production, Worker Capacity and Storage Multiplier to AI Labs. Provides +1 Production and Storage Multiplier to AI Lab for each level of Information Age Wisdom. Provides +1 Building Level Boost to AI Labs for every 5 happiness (capped)

Natural Wonders


Aurora Borealis: All buildings that do not produce workers within 2-tile range get +X Production Multiplier. X is based on the time since the wonder was discovered


Lake Louise: All trade map neighbors become allies (regardless of civilization). Each ally tile provides +2 Building Level Boost


Dinosaur Provincial Park: This wonder can be activated at a chosen time to gain a one-time Koti equal to %{percent} of the empire value at that time

Great People


Terry Fox (Cold War): +2 Production Multiplier, Storage Multiplier for TV Station


Geoffrey Hinton (Information Age): +1 Level to Habitat 67

Festival


Winter Carnival: Double the range of Aurora Borealis. Double the Building Level Boost from Chateau Frontenac and Habitat 67

New Civ: Russian (50x50)

I’d like to remind everyone that including a Russian civilization in a historically based 4X incremental game is not an endorsement of, nor a commentary on, current-day geopolitical events.

Unique Buildings


Cosmodrome (Space Program): Rocket x4 + Satellite x4 + Airplane x4 => Spacecraft x2


Kizhi Pogost (Alloy): All buildings within 3-tile range get +X Production Multiplier. X = the production multiplier this wonder receives


Hermitage (Journalism): This wonder can be upgraded and each level provides +1 Storage Multiplier to each type of building within 2-tile range


Sputnik 1 (Satellite): This wonder can be upgraded and each level provides +1 level to all Cold War Age great people for this run (excl. Great People that provide level boost) and +1 Production, Storage Multiplier to Cosmodrome. Provides +1 Production and Storage Multiplier to Cosmodrome for each level of Cold War Age Wisdom


Akademik Lomonosov (Genetics): This wonder can be upgraded and each level provides 100KW of power. Provide power to all tiles within 2 tile range. This wonder can be moved

Natural Wonders


Lake Baikal: +X Builder Capacity Multiplier. X = total levels of wonders within 2-tile range

Great People


Tchaikovsky (Industrial): +1 Level to Hermitage


Andrey Kolmogorov (Cold War): +1 Production Multiplier, Storage Multiplier for Satellite Factory, Cosmodrome

Festival


Maslenitsa: Double the range of Kizhi Pogost and Lake Baikal. Double the power output of Akademik Lomonosov

New Achievements

  • From Sea To Sea: Rebirth with at least 1 Extra Great Person when playing Canadian (Reach 64M Empire Value when rebirth)

New Wonder: World Trade Organization

World Trade Organization (Financial Leverage): This wonder can be upgraded and each level provides +1 Production Multiplier to Trade Tile Bonus buildings. Participate in WTO vote each week that increases the chance for the voted buildings to appear in the next week's Trade Tile Bonus

Balancing

  • Library: 4 Paper -> 140 Science (from 3 Paper -> 105 Science)
  • School: 2 Faith + 2 Poem -> 800 Science (from 1 Faith + 1 Poem -> 400 Science)

QoL

You can now pin a Todo tab to the leftmost position. A Todo tab for unselected adaptive great people boost is also added

The empire value tooltip now includes more details about the current run.

Bugfix

  • Fix a bug where checking in/out save across different platforms will result in loss of Offline Production / Warp

Game update4 Sep 2026New Player Trade Limit For Account LevelHi, The trading server has been updated with limit for different account levels. Here are my rationale for this change. Max Tariff Max Tariff has been 10% since the Player Trade was initially introduced. It worked alright until "Tile Claim" was introduced, which made trade map more crowded and tariff more prevalent. This hinders player trade and is prone to abuse. Lowering tariff rate, especial…Steam news16 Aug 2026Now In Beta: Patch 1.5Greetings, CivIdlers, I am preparing a “surprise” content patch for CivIdle (well, not a surprise anymore) to celebrate the release of Restitutor.

This would have been enough to cover the server costs for almost a year! However, our hosting provider has raised the price by almost 300% . This would have been devastating, but the proceeds from the DLC have bought me a bit mor…
