Cogs is an innovative puzzle game where players build an incredible variety of machines from sliding tiles. Immersed in a steampunk world with stunning visual design, Cogs is pure eye candy. Players can choose from 50 levels and 3 gameplay modes. New puzzles are unlocked by building contraptions quickly and efficiently. - Inventor Mode: Starting with simple puzzles, players are introduced to the widgets that are used to build machines — gears, pipes, balloons, chimes, hammers, wheels, props, and more. - Time Challenge Mode: If you finish a puzzle in Inventor Mode, it will be unlocked here. This time, it will take fewer moves to reach a solution, but you only have 30 seconds to find it. - Move Challenge Mode: Take your time and plan ahead. Every click counts when you only get ten moves to find a solution.

This ia an absolutly perfect game in its genre.
It takes a simple idea (the game of fifteen) and expands and implements it in a perfect way, : visuals, sounds, game play, repeatability, difficulty progression ...
A lot of work and love has probably been input in this game, resulting in a great game for the whole family.
Kudos !
