Goparokko

Goparokko is a tile matching puzzle game. The playing field consists of a 7x7 grid of colored blocks. The player has a selector that can be used to highlight any 4x4 square of these blocks, and can click to rotate that selection clockwise by 90 degrees. The object is to spin the blocks to create matches of 4 while competing against the timer, represented by a draining container of water. Creating matches adds a small amount of water to the container, but the longer the game is played, the faster the water will begin to drain.

Certain special tiles can help or hinder the player, most of which activate when used to make a match. Alongside simple multiplier and wildcard tiles are ones that reset the water level to maximum, destroy all non-special blocks of the same color, and guarantee the generation of a block of a specific color when a match is made. There are also locked tiles, which prevent the player from rotating a selection containing one.
