Blasto is a 1978 arcade action game developed by Gremlin, arriving during one of the most fertile and competitive periods in early arcade history. The late 1970s saw the coin-op market rapidly expanding in the wake of Taito's Space Invaders (also 1978) and Atari's earlier Breakout (1976), and Gremlin — a San Diego-based developer known for pushing simple but engaging mechanics — contributed Blasto to that crowded landscape. The game predates the golden age peak of Pac-Man and Donkey Kong by two to three years, placing it firmly in the era when developers were still discovering what arcade hardware could do and what players would pay a quarter to experience.
Blasto is a fixed-screen shooter in which the player controls a cannon or turret positioned at the bottom of the screen. The core objective is to fire projectiles upward to destroy a field of targets arranged across the playfield. The mechanical loop is straightforward: aim, fire, clear the screen, advance. The controls are typically a directional input for traversal or aiming and a single fire button, keeping the barrier to entry extremely low — a deliberate design choice in an era when arcade operators needed games that could be understood within seconds of inserting a coin.
What distinguishes Blasto's structure from contemporaries is its use of a grid-based target arrangement that the player must systematically eliminate. Unlike the marching alien formations of Space Invaders, Blasto's targets are stationary or move in constrained patterns, placing the emphasis on the player's accuracy and shot management rather than reactive dodging. The game loops through increasingly difficult configurations as the player clears each screen, with target density and movement speed ramping up to sustain challenge over extended play sessions.
The cabinet itself was a standard upright design typical of Gremlin's output in this period, using a black-and-white or color raster display depending on the regional variant. Sound design was minimal but functional, relying on the beeps and electronic tones characteristic of late-1970s arcade hardware to provide feedback on hits, misses, and stage completions.
In its era, Blasto occupied a niche as a competent, accessible shooter that appealed to arcade operators looking for reliable earners. It did not achieve the cultural dominance of Space Invaders or Asteroids, but it held its own on the floor of arcades, bowling alleys, and pizza parlors where Gremlin cabinets were a common sight. The game reflects the design philosophy of its moment: strip the experience to its essentials, make the feedback loop satisfying, and trust that the escalating difficulty will keep players feeding coins. For historians of the medium, Blasto is a useful data point in understanding how the shooter genre diversified in the months immediately surrounding Space Invaders' seismic impact on the industry.
