The app presents a game where users select groups of three or more same-colored squares to clear them from the board. New rows of squares fall from the top, and clearing a specific number of rows advances the user to the next level.
Play by dragging and dropping blocks onto a grid to complete lines horizontally or vertically. Clear lines to score points and progress through levels. Unlock new shapes and themes as you advance. Compete with others in online leaderboards.
The app allows users to play chess, analyze games, and solve exercises. It includes features for online play, game annotation with comments, and a stable connection to the FICS server.
