Stack Attack Classic is a puzzle game in which you choose a worker and organize stock by creating chains of colored boxes to earn points. This updated take on a classic phone game combines a familiar stacking premise with several ways to play and additional unlockable content.
Chain-based stock organization
The central play loop focuses on arranging colored boxes into chains. Building these chains is tied directly to scoring, while bonuses and secrets provide additional discoveries during play. Progress also leads to hidden characters, special rewards, and power-ups, giving the basic organization task further goals beyond earning points in a single session.
Four game modes
Stack Attack Classic offers four modes: Classic, Arcade, Logic, and Hardcore. Each mode provides a different framework for approaching the same core box-organizing premise, allowing the game to support both the traditional format and more demanding or distinct challenges without reducing the experience to one rule set.
Progress tracking and competition
Online leaderboards let players compare their results with others, while achievements record completed accomplishments. These systems connect individual scoring and progression with longer-term goals, including the pursuit of higher leaderboard positions and additional unlocks.
Playing on a computer
The game can also be used with PC emulators such as BlueStacks, with keyboard controls available in that setup. The source describes Stack Attack Classic as free to play without in-app purchases.
