sp is a challenging puzzle game available on iPhone. Developed by General Adaptive Apps Pty Ltd, it offers an engaging gameplay experience with its unique concept and captivating features.

In sp, you are tasked with navigating spiral radiuses that expand and contract. Timing is crucial as you aim to complete each level. As you progress, the game becomes more complex, offering theoretically infinite solutions to each level. This adds a layer of excitement and fun to the overall experience.
