Blockade

Blockade is a pioneering 1976 arcade game developed and published by Gremlin Industries, widely recognized as the foundational title that spawned the entire global snake game subgenre that remains popular across mobile, console, and browser platforms half a century later. Released at a time when the arcade industry was still in its infancy, riding the wave of Pong’s mass success, Blockade introduced a completely original competitive gameplay concept that broke away from the dominant sports-themed arcade titles of the era. The core premise is simple: two players each control a continuously moving block that leaves a solid, impenetrable trail behind it as it travels across the grid-based monochrome screen. The only rule is to avoid colliding with the screen borders, your own trail, or your opponent’s trail, with the first player to crash losing the round and the surviving player earning a point. Controlled via simple four-way joysticks for each player, Blockade was designed to be easy to

Game Guide

If you’re new to Blockade, follow these actionable tips to outplay AI opponents or friends and win more rounds consistently. First, master the basics of movement: your block travels at a fixed, unchangeable speed and only turns in 90-degree increments, so never make sudden, unplanned direction changes. Over 60% of beginner losses come from accidentally turning directly into their own trailing line right behind them, a mistake that usually happens when players react impulsively to an opponent’s move without checking their own position first. For the first 10 seconds of every round, stick to your half of the screen, laying down long, straight trails to create wide, open lanes for yourself instead of rushing to the center to confront your opponent. Rushing early almost always traps you in a small section of the screen before the match even heats up. Once you have a safe base of open space, start reading your opponent’s movement patterns. If you notice they consistently move toward the nearest open edge to get more room, you can cut them off by laying a short trail across their predicted path 2 to 3 moves in advance, forcing them to either crash into your trail or turn into a much smaller, more confined space. For advanced play, use baiting tricks: leave a small, seemingly open gap in a ring of your own trails, and most opponents will try to dart through it to cut you off. As soon as they enter the gap, turn quickly to seal the entrance, trapping them inside the small enclosed space where they will inevitably crash into their own trail within seconds. Avoid the four corners of the screen whenever possible, as they leave you with only two possible directions of movement, making you extremely vulnerable to being trapped by a well-timed block from your opponent. When playing single-player mode against the AI, remember it follows predictable logic: it will always prioritize blocking your path over protecting its own open space, so you can lead it into large, looping pattern
