Tetra Quest is one of the Tetris Games that you can play on UGameZone.com for free. Tetra Quest will take you on an adventure set in a world of witches and mythical creatures! Join the good little princess and try to rid the citadel, the mystery forest, and the deserts of evil spirits. To complete the levels, start by tapping or clicking on the silhouette of the block. This allows you to place it on the board. Your objective is to fill the horizontal rows, clearing all of the blocks. To finish the level, you will have to break the haunted orbs and mirrors! You can rotate the blocks, or place one aside to save it for later, but be aware that every move counts toward your total score.
