Cogs is a multi-award-winning puzzle game where players build increasingly complex machines using sliding tiles 3D. Originally launched in 2009, we completely remastered Cogs from the ground up in 2025 to look beautiful on modern phones and tablets. "One of the highest quality puzzle games we've seen." – PocketGamer "The visual design and imagination of the game are stunning, with great attention to detail, and the sound effects are downright enticing." – Adrenaline Vault "A masterpiece visually, as well with the actual gameplay." – AppAdvice 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 tap counts when you only get ten moves to find a solution.

Verdict
The clearest difference is price: Solitary Confinement at Free against Cogs's $4.99. Solitary Confinement also leads on in-app purchases (none vs 4) and update cadence (every 5 days vs every 2 months). Cogs's advantage is ratings volume (33 vs 4) and iOS requirement (13.0 vs 17.6). On ads and device support there is nothing between them.
