Trickle is now powered by Claude 4

We recently upgraded Trickle’s AI model to Claude 4. The improvement in reasoning, structure, and code quality has been clear across the board.

To see how far we could push it, we gave it a single-line prompt:

“Build a fully functional Tetris game with clean UI, basic controls, score display, and level tracking.”

Tetris game generated in one go on Trickle with Claude 4.

What came back wasn’t a half-finished prototype. It was a fully working game, with:

• Live score and level tracking

• Pause, restart, and drop mechanics

• A clean sidebar UI with keyboard instructions

• Well-structured layout and game logic

• Minimal to no tweaking required

All of this was built in one go, using Trickle’s AI coding environment.

Why it matters

Claude 4 doesn’t just write better code. It understands what you’re trying to build. In this case, it got the rules of the game, the pacing, the UI layout, and even subtle UX elements like control visibility and restart behavior.

This kind of quality used to take multiple rounds of iteration. Now it happens on the first try.

Try it out

Claude 4 is now the default in Trickle. If you’ve been curious how far prompt-based building can go, this is a good moment to find out.

You can try building something yourself at trickle.so

Would love to hear what you’d experiment with using just one prompt.
