Strata is a challenging but innovative puzzle game based on colors and sounds.
The aim is to strategically layer colored ribbons to match patterns which get increasingly more complex. Strata has a soothing piano soundtrack which suits the mood of the game which is all about strategic thinking to create weaved patterns.
Strata is definitely something different in the puzzle genre. The full screen ads are the only annoyance but you can remove this by getting the paid version.
