Stack Top-Up is a free Android game developed by Marionette. The game requires players to stack plates on a platform as high as possible using only one finger. With simple gameplay, it is easy to pick up but challenging to master.

The game features a minimalist design and easy-to-use controls. The plates are stacked on a platform that moves back and forth, making it challenging to keep the stack balanced. Players must have good concentration and timing to achieve high scores.

Overall, Stack Top-Up is a great game for anyone looking for a quick and fun challenge. It is perfect for passing the time and improving your concentration skills. However, it does lack additional features and modes that could make the game even more engaging.
