FOE Tools, a set of tools to simplify life on Forge Of Empire

Not open for further replies.



In this start of the new year, I share you a tools that I have developped to simplify your life on FOE.This set of tools are designed to rush GB.

One tool will help you calculate the number of FPs you need to secure a place on Great Buildings, another (integreted on the first and also in standalone version) to calculates the number of FP that a player must put on a GB to block his place.


The project is OpenSource and the website is hosted on GitHub. Thus, everyone with the necessary skills can participate in the improvement of this site.

Note: English is not my main. So, if you find mistake in text, please tell me and I will correct that.

GB Data can be found here: GM 1.9 @ Yoratheon (Grameen)

New version, 1.5.0:

Arrival of a new tool, the "Château Frontenac Calculator". This tool allows you to predict the number of resources needed for recurring quests based on the fact that you are rushing Rinbin's quest "non-birthday party" and also allows you to estimate the rewards obtained.

Improvement in the secure place tool. You can now enter the bonus of your Arc and the number of FPs of the target place, this will tell you if you will win or lose FPs (or no profit / loss).

Added a page that list direct and indirect contributors of the project.
Added a page (only available in english) that displays change log.
The site is now available in Russian.


Hello everyone,

It is with great joy that I announce you the release of the new version of the site: 2.0.0

This new update brings a lot of change. First, I changed technology to develop the site, which involved redeveloping it entirely.

Add 2 new tools :
- GB Statistics
- Forecast cost GB

The first one allows you to visualize several graphs on the evolution of the costs and the gains of GBs.
The second lets you know how many FPs are necessary to go from one level of a GB to another, with or without help of big Arc.

Improvement of the promotion message

In "GB Investment", a column was added to tell for each place if are free or not. If it is, it will be added to the promotion messages.
Promotion messages can now be prefixed and suffixed.
You can also easily copy a message with a button just to the right of it (for browsers that support it, normally, all recent browsers)


Add GB: "The Blue Galaxy"

When you visit a permanent link, a message appears at the top of the page to inform you that the changes you make will not be saved in cookies.

Added a cookie disclaimer message to tell the user that the site uses cookies

Added permanent link in "Secure place" and "Château Frontenac Calculator".

Add sub-url by language ("/fr" for French, "/de" for German and default "/" for English)

Fixed the problem of cookies expiration.

Fixed infinite calculation in "Château Frontenac Calculator" when more resources were spent than needed to complete quests.

Update and data corrections on GBs

The style of the site has slightly changed.


Note: normally, there is no need for buttons to start calculations. If the calculations are not done automatically, it is that your browser is not recent enough (or does not follow certain standards of the web). If the problem occurs to many people, I will re-add them.

Good evening everyone,

On the eve of another update of FOE, I announce you a new update of FOE-Tools: 2.6.0

Improve GB-Investment

A "new" tool arrives, I say "new" in quotation marks because it is a different vision of a tool already existing on the site:

The "GM Investment" tool now has 2 different views, the first is the one that was there from the beginning and is called "Owner View", the second and an investor-oriented view and is called "Investor View".

This view allows to see the gain that can be obtained by taking a place with or without taking into account investments in other places. There are 3 types of consideration of other places:

No do not take into account other places
Normal take into account the other places with a minimum investment of investors and without securing by the owner
Optimal take into the account the other places with an investment without profit of the investors and with securing by owner

Virtual Future

Added the first 81 levels of the GM "Terracotta Army" of the virtual future (coming out tomorrow).

Adding Levels

Added levels 81 to 106 of the High Middle Ages
Added levels 153 to 156 of the Progressive Era
Added levels 81 to 110 of the Postmodern Era.
Added levels 142 and 143 of the Future Era

Some minor minor corrections.


Good evening, again a new update: 2.8.0

  • Adding the Virtual Future in the "Château Frontenac Calculator"
  • Addition of the first two sectors of the Virtual Future (for the tool "Campaign Cost")
  • Added an option to display the level in promotion messages
  • Fixed the tab change in "GB Investment" (the favorite view was saved by GB instead of globally).

I also updated the contributions page by improving the display and trying to identify all the people who contributed directly or not to the project.

New version: 2.17.0

In "GB Investment", improvement of the display of the current level (some people had trouble knowing is when we put 10 is on the level 9,10,11 for example).
Now, if we put level 10 it tells us: Level 9 → 10.

In some cases, the number of FPs to be put by the owner for the P2 to P5 is lower than the previous places (example: the previous of P2 is P1), it is possible by relying on the fact that people have taken the previous places, to overcome the problems of understanding ensuing, if the number of FPs of the owner is lower than the investments he has to put for a previous place (P1 for example), he takes the cost of the previous place.
