In this reinvention of the classic arcade game, the well-known pixel robots join forces with hyperspace rockets, pink asteroids, electrical energy balls, and supreme comets. Pixel Invaders is a 7x7 cascading reel slot game in which symbols drop down on the reels to form winning combinations. Achieve your wins by landing five or more matching symbols that are connected vertically or horizontally. Winning symbols are removed, and new symbols drop down to fill the reels. Feel the cosmic energy as ENERGY BALLS randomly appear to destroy the symbol where it lands together with all four adjacent symbols. Up to three Energy Balls can land simultaneously both in the base and bonus game. Look out for the SUPREME COMET as it randomly appears to destroy all symbols on an intersected row and column in both the base and bonus game. During the base game, charge the FUEL LEVEL METRE to trigger any of the four different levels of FREE SPINS—ARION, CALYPSO, HYPERION or TITAN—by landing four to seven rocket Scatters. You will also get a Mega Wild 2x2 when triggering Level 3 (Hyperion), and morphing symbols when triggering Level 4 (Titan). When in Free Spins, the rocket Scatter will give you an added push and take you up an extra level. Pixel Invaders comes with a BUY BONUS with which you can buy four Scatters to reach Free Spins Level 1, five Scatters to reach Free Spins Level 2, or a Surprise option that will randomly give you six or seven Scatters that will trigger Free Spins Level 3 or 4.
