QIX (1981 Arcade): Draw Lines to Control at Least 75% of the Stage

1981 Arcade Line-Drawing Action from TAITO

QIX is an action game released in 1981 for arcades by TAITO. The player controls a marker that draws lines to claim territory. The stage is populated by QIX, a swirling entity, and Sparx, hazards that roam the playfield. The objective is to draw lines and enclose areas to control at least 75% of the stage. Players must avoid contact with QIX and Sparx while drawing. The game combines line-drawing mechanics with real-time hazard avoidance, requiring careful positioning and timing. The arcade version uses a joystick and buttons to move the marker and draw lines, though specific control details are not documented in the available sources.

The player's marker moves along the borders of the playfield and through already claimed areas. To claim new territory, the player draws a line into unclaimed space. If the line is completed back to a border or claimed area, the enclosed region becomes part of the player's territory. The QIX floats in the unclaimed area and must be avoided; touching it costs a life. Sparx travel along the borders and can also cost a life if they touch the marker or its drawn line. The percentage of claimed territory is displayed, and reaching 75% advances the game. The QIX and Sparx move at varying speeds, adding challenge to the line-drawing process.

The Marker: Drawing Lines to Claim Territory

In the 1981 arcade game QIX, the player operates a Marker to draw lines across the stage. These lines serve to close off and control areas of the playfield. The central mechanic is that by drawing lines, the player can enclose regions, which then become claimed territory. The game's objective is to control at least 75% of the stage, requiring the player to strategically partition the space. The Marker moves along borders and through already claimed areas, and when a line is completed back to a border or claimed area, the enclosed region is added to the player's territory. This line-drawing process is the primary means of expanding control.

The act of drawing lines is governed by the game's system of area control. Players must avoid the hostile QIX and Sparx that roam the stage while drawing, as contact with them costs a life. The QIX floats in unclaimed space, and Sparx travel along borders, adding a layer of hazard avoidance to the line-drawing mechanic. The percentage of controlled territory is displayed, and reaching the 75% threshold advances the game. This creates a dynamic where the player must balance the speed of drawing lines with the need to evade moving threats, making each line drawn a risk-reward decision in the quest to maximize controlled area.

QIX and Sparx: Hazards Roaming the Stage

Two hazards share the stage while the player draws: the QIX and the Sparx. Both are documented as roaming the stage, which spans the space the marker must cross when it leaves the border or claimed ground. The player controls the Marker to draw lines that close off and control areas, and the same description lists the QIX and the Sparx as hostile entities to avoid. Because the hazards travel the playfield rather than sitting in one spot, a line under construction stays exposed for as long as it takes to reach a border or claimed region.

Avoidance works together with the area goal: the same game description tells players to avoid the hostile QIX and Sparx while working to control at least 75% of the stage. Reaching that threshold is the stated win condition, so each draw is made under the roaming hazards' pressure. The marker only claims ground when a line closes a region, meaning unsafe positioning suspends progress. The rule set therefore ties survival directly to area control: keep the marker clear of both hazards while drawing, and keep enclosing regions until the claimed total reaches the 75% mark.

The 75% Objective and Modern Reissue Context

The stated objective in QIX is to control at least 75% of the stage. Players operate the Marker to draw lines that close off and control areas of the playfield. Once the claimed territory reaches this threshold, the objective is met. The game also encourages maximizing the controlled area percentage, so drawing lines to enclose ever-larger regions serves both the minimum win condition and a higher score or completion metric. The 1981 arcade release, published by TAITO, presents this line-drawing puzzle as an action game where the player's progress is measured directly by the percentage of the stage under control.

The modern Arcade Archives reissue reproduces the classic arcade game and stays true to its original. It adds customization options, such as adjusting the difficulty level, and for some titles, a mode that recreates the nostalgic atmosphere of CRT televisions. Players can also compete for high scores with others around the world through online rankings. These features belong to the reissue, not the 1981 arcade release. The original QIX, developed by TAITO America and imported into Japan, remains a line-drawing puzzle where the player avoids the QIX and Sparx while working to control at least 75% of the stage.
