Independent Games Festival Mobile 2008 Finalist.

Backflow is a casual-style puzzle game for mobile phones. In the game you take control of the waste disposal infrastructure for a city. It's your job to make sure each type of waste goes to the right place.

By flipping switches on pipe intersection points you direct the flow of waste to processing facilities at the bottom of the screen. Earn points by sending recyclables to the right bins. Create combos by sorting 5 waste items consecutively without any mistake. Look out for power ups to help you along the way; there are 3 power ups, a health power up, a slow-down power up and an instant multiplier power up.

Each mistake will break your combo and increase the pollution in your city!

As your city grows in population, waste comes out faster and more frequently. Try to manage the biggest city without getting buried in the garbage!

There are 3 difficulty modes in the game, easy, medium and hard. Upon completing the different difficulty modes, you'll unlock the challenge mode.

  1. Multiplier power up will be removed

    Bins will be randomized and made unidentifiable, players will need to sort the items by memory

The Survival Mode

Levels will be unlocked in the survival according to the player's progress in the game and players can choose to take on any levels in a arcade style survival mode and compete for the highscore.
