Based on an arcade game of the same name, your goal in Ultimate Block Party is to eliminate blocks from a board by grouping like-colors together. You can rotate groups of four blocks left and right. Lining up four pieces of the same color makes the pieces disappear from the board. As the four pieces are disappearing, you can continue connecting more pieces to the group, adding to a growing chain of piece annihilation. You can add an additional row with a quick button press (this is an advanced technique for those who don't have enough pieces to make combos), although rows are also added automatically as time progresses. If your stack of blocks hits the top of the screen, you lose!
