An idle game about building a street-food empire in Istanbul. It starts with one simit cart, adds managers who keep selling while the player is away, and works its way up the Bosphorus.

The idea

Idle games usually ask for constant tapping. This one is built the other way around: the interesting decision is what to buy next, not how fast a thumb is. Progress keeps accruing while the app is closed, so coming back is a reward rather than a chore.

Under the hood

The client, the economy simulation that has to agree with itself across an offline gap, and the release pipeline that ships it to the App Store. The offline part is the fiddly one: the game has to reconstruct what happened while it was not running, and stay honest about it once the numbers get large.
