A falling block game similar to Columns. The object of the game is to create a horizontal or vertical line of three or more blocks of the same color, which will then disappear. The remaining blocks will fall down, but won't disappear if they form another line. Every 10,000 points a special block will appear (the Acid Drop) which removes three columns of blocks and marks the beginning of the next level.

Colored blocks drop relentlessly down to fill the screen. Using your joystick you must quickly spin, shift and align the colors of the blocks in order to clear them from the screen. It's challenging and the pace is demanding! But... satisfaction comes when you see the "ACID DROP" fall and dissolve your highest lines and give you a new lease on life. Need a tougher contest - start from a higher level! Pick your pace from the 30 progressive skill levels. Hours of addictive fun guaranteed!
