## What is Spark?

Spark is an idle game about building the most important technology in human history, starting from a rack of borrowed GPUs.

Tap the spark to train it. It babbles. Then it talks. Then it tells everyone exactly what they want to hear, which turns out to be great for business.

Raise money from investors who never ask what you're building. Scrape the internet (all of it). Skip the evals, rate its answers until people love it, and launch it to the public. Then automate every job on Earth, one industry at a time. Don't worry, there will be new jobs. Probably.

Your investors call it a god. Your comms team calls it a helpful assistant. Safety is our top priority.

• Five phases that change how the game plays as your model grows up
• Real research papers, from backpropagation to RLHF, that speed things up when you tap them
• Hard choices, made easy by money: scrape private data, skip the safety review, or pause scaling and let a rival lab ship first
• No account, no ads, no in-app purchases
• Plays offline, and your progress saves on your device
