Powerhouse - Circuit Scramble for iPhone

Quick overview

Powerhouse — Circuit Scramble is a free puzzle game that challenges your logical thinking with circuit-based problems. It combines slide-puzzle mechanics and electronic logic so you can learn how different components interact while solving increasingly tricky layouts.

How the game works

You move pieces across a board of components to route signals and discover the correct inputs for each circuit. Puzzles require planning and an understanding of how parts behave; solving a circuit often means composing a sequence of moves that connect sources, components, and outputs in the right order.

Parts you'll encounter

• LEDs and other output indicators, which show whether a path is powered
• Transistors used to switch or amplify signals
• Diodes that permit current in one direction only
• Voltage divider arrangements for creating intermediate voltages
• Miscellaneous electronic elements that introduce special rules and interactions

Each item follows its own rules, so mastering their interactions is key to progressing.

Puzzle variety and daily content

There are hundreds of levels to tackle — over 700 distinct powerline puzzles — and the game adds a fresh daily challenge. Completing circuits increases your rank, improves your score, and raises the rewards you can earn from daily tests.

Progress tracking and competition

Powerhouse supports Google Play cloud synchronization so your progress carries across devices. It also offers 25 achievements and two leaderboards, giving you clear goals and a way to compare skills with other players.

Why it’s worth a try

The mix of addictive puzzle design, increasing difficulty, and educational value makes Powerhouse — Circuit Scramble a compelling choice for anyone curious about electronics or who enjoys logic games. It’s both a brain workout and a hands-on introduction to basic circuit concepts.
