Pixel Invaders by GameArt is a 7x7 cascading reel slot with wins formed by five or more matching symbols connected vertically or horizontally. After each win, the winning symbols are removed and new symbols drop into place, creating chain reactions within the same round. The game is listed with medium-high volatility and an RTP range of 96.33% to 97.22%.
Special features include Energy Balls, which can appear randomly and clear one symbol plus the four adjacent positions, with up to three appearing at once in the base game and bonus game. The Supreme Comet can also land randomly to remove all symbols on a crossed row and column. Rocket Scatters build the Fuel Level Meter and trigger one of four free spins levels: Arion, Calypso, Hyperion, or Titan.
During free spins, the rocket Scatter can push the bonus up a level, while Level 3 awards a Mega Wild 2x2 and Level 4 introduces morphing symbols. A demo version is available for players who want to play for free and practice before playing for real money.
