Switcho is a block stacking/matching game where the object is to clear blocks by getting at least 4 matching blocks in a row vertically, horizontally or diagonally. In "Right Left" mode touching a block switches the block to right with the touched block. In "Up Down" mode touching a block switches the block above it with the touched block. Use the blue arrows at the bottom to change modes. A new row pushes the blocks up as time goes by.
