Rukji Eggs Fall is a puzzle-based game where players strategically control the drop of various items into a container. Items that touch identical ones will swap positions and increase their level, contributing to higher scores. The game incorporates boosters to assist in progressing through levels. The settings allow for adjustments to the sound and music for a customized experience. Players can access different screens, including the game area where the items fall, the settings dialog for audio preferences, and a game completion screen to review the score. A warning screen will appear if there are insufficient resources for the next move.
