Zero Below Zero

So you think this game looks easy? Be prepared to stare at the screen in puzzlement, to try so many different moves that you start to lose hope, to start questioning if the developer made a mistake - maybe this level really *is* impossible to complete?

It isn't.

The goal of Zero Below Zero is simple - all of the circles must not be below zero.  When you tap a circle it reduces in value, and any connected circles go up in value. Some levels allow you to remove connections, add connections, and add multipliers between the circles. All elements have been thoughtfully constrained to produce the most challenging and interesting levels.

Most levels have millions of permutations of possible moves - but only one will solve the level in the minimum number of moves. This number will only be revealed to you once you complete the level. If your score is not perfect, will you try again to improve it or move on to another level?

The interface is relaxing and gentle with no adverts. Take a moment every now and then to watch the soothing backdrop meander along. And make sure to try out dark mode for a stunning planetarium like experience!

If you are stuck on a level don't worry, you can always move to a different level. Once you have unlocked the game, there are 82 carefully crafted levels to enjoy. You could either go through each level one by one, or flip between the levels as you wish.

Zero Below Zero has many hours of gameplay just to complete all the levels - and many more to perfect them.

Enjoy the first 19 levels for free and with no adverts. A one-time purchase unlocks all 82 levels.

Zero Below Zero is inspired by the Dollar Game as seen on the Numberphile YouTube channel. By adding the ability to remove connections, add connections and add multipliers, the game has taken on a new dimension.
