Features & Capabilities

Gear Combination is a puzzle game where you connect gears to solve challenges. How to play: Select a quest and a spinning gear will appear in the upper-left corner. Your goal is to connect the gears provided on the right to the main spinning gear to complete the quest. Gears can be placed freely in any position.

Features include 40 unique quests, non-linear progression, and replayability—play completed quests as many times as you want. Technical note: clockwise rotation is positive speed, and counterclockwise rotation is negative speed.
