**GPU Puzzles Blog Series - My Learning Experiences**

_Companion materials for Mojo GPU Puzzles (Puzzles 1-8)_

I’ve been working through the official Mojo GPU Puzzles ([https://puzzles.modular.com](https://puzzles.modular.com)) on Apple Silicon M1 & M5 and I am documenting my solutions and learning process in a blog series. Hopefully they might be useful to others.

**What’s covered:**

- So far Puzzles 1-8: Thread basics through shared memory

- Both UnsafePointer and LayoutTensor approaches for applicable puzzles

- Solution code clearly marked

- Practical gotchas I encountered (missing barriers, bounds checks, etc.)

**Links:**

- Series introduction: [GPU Threads Unraveled: A Hands-On Series Learning GPU Programming in Mojo](https://www.databooth.com.au/posts/mojo/gpu-puzzles-outline/)

- Post #1 (Puzzles 1-2): [GPU Threads Unraveled #1: First Threads – Launching into Mojo GPU Basics (Puzzles 1-2)](https://www.databooth.com.au/posts/mojo/gpu-puzzles-post1/)

- Post #2 (Puzzles 3-8): [GPU Threads Unraveled #2: Grids, Guards, and Shared Scratchpads (Puzzles 3-8)](https://www.databooth.com.au/posts/mojo/gpu-puzzles-post2/)

- My fork with solutions: [GitHub - Mjboothaus/mojo-gpu-puzzles: Learn GPU Programming in Mojo🔥 by Solving Puzzles](https://github.com/Mjboothaus/mojo-gpu-puzzles)

These are designed as a complement the excellent official tutorials. **Comments/corrections welcome.**
