HOP & POP is an Android game developed by The Mascoteers. It is a collection of minimalist arcade games that offers both limited and infinite modes. The game consists of six different game modes: Duckling, Dotzy, Stairway, Nail it, Qubely, and 360 degree.

In Duckling, you must navigate an obstacle course while moving laterally to hit diamonds and avoid collisions with slabs and blocks. Dotzy requires absolute control over timing as you operate a stick with a pendulum motion to hit objectives. Stairway challenges you to use gravity to your advantage and tap at the right time to change direction while avoiding spikes. In Nail it, you must hit the nail and diamond while avoiding other objects put in place to confuse you. Qubely is a stacked mountain made of stairs that constantly builds and breaks itself, and it's up to you to climb safely while hitting diamonds. Finally, in 360 degree, you must tap and spin a colored circle wheel to avoid spikes and earn diamonds.

Overall, HOP & POP is an enjoyable and challenging game that will put your reflexes to the test. Note that the app may require read and write permissions to your storage for the score share feature.
