We are now ready to announce the date when Eiffel Tower will be available in Idle Tower Builder.
Since 11.11.2026 you'll be able to access it from the babel Tower via Menu - Map of Towers - Eiffel Tower, just like this:
The system of game worlds within a single game will let you switch between the towers, and while you are actively playing one, the offline time bonus will be stores in another.
Eiffel Tower presents new playing experience of constructing the tallest tower in the world, while keeping the original atmosphere and fun of Babel Tower building. Some of the gameplay concepts are reimagined for new ways of interaction
Trading resources. In Babel Tower you can simply press "Market" button and sell the whole amount. While designing Eiffel Tower trading system we decided not to repeat ourselves, but provide a player with an interesting way to control the prices. First you build a railway station. Then you start receiving trading offers from arriving wagons. and it's your choice, whether to accept or to decline these offers. Declining several offers will increase the price of the next one. So the players decide - should they receive some money sooner, or a bigger amount, but later.
Offline time bonus. The very first version of Babel Tower had it, and players were asking to return this mechanics. So we are returning it in the Eiffel Tower. When you return to the game after some time away, the games gives you bonus time. And then it's your decision, at which moment to activate this bonus time to receive production and construction speed-up.
Resources conversion. As the game's setting is in the Industrial age, multiple steam engines and resource transporting conveyor belts are present. The control center for all those conveyor belts is underground, and you'll be able to toggle their switcher, speed up and upgrade. Just look how these conveyors are working! Such a relaxing view!

BTW, fun fact: in our first attempt to create Eiffel Tower world for Idle Tower Builder in 2021 we designed a system of resource conversions and transporters, and this system turned into a whole new game, Farm and Mine! Have you tried it?
With new content of the game, some things remain the same. Main is our attitude to mobile ads. Entire game can be completed without watching a single ad. Ads are shown only if the player requests it by pressing the "reward" button. Thanks to that many player rate Idle Tower Builder highly and the game's rating is 4.5-4.8 of 5 in AppStore and Google Play.
As for AI usage, we are sticking to the good old attitude of creating games, not generating them. All the game art and code, as well as the ideas and balance formulas are made by real humans. Here is a timelapse of how a work in this mode looks like:
I used the same approach for creating this post as well: I just opened my laptop, and by striking keyboard keys began bringing my own thoughts to the screen :) Hope that players will value our human-centered approach.
The only field we do use AI helpers (and where they proved to be extremely helpful) is game texts spellchecking and translating game into the languages for which player translators couldn't be found. In fact, universal translation was one of the fields for AI defined at the first scientific AI conference back in 1960s.
Due to game code structure, possibility to switch between towers withing a single game will be available only in the standalone versions of Idle Tower Builder. You can get them from

If you are playing the HTML5 version of Babel Tower (Youtube, Poki, etc) we recommend you to switch to the mobile version. It's easy: press Menu-Backups-Export in the Youtube version, copy your save file as a plain text, send it to yourself, and then from your mobile device copy the save text to clipboard and press Menu-Backups-Import.

Time before the release we are going to spend by polishing new game world: playtesting, readjusting and fine-tuning game balance, adding achievements and leaderboards and designing some additional steampunk machines which will be unlocked as Eiffel Tower will be reaching its full height.
