The best next step after the Cast Diamond is a Level 2 puzzle like the Cast Hook or Cast Keyhole. Both offer a slight increase in challenge—Cast Hook takes about 2-5 minutes for most beginners—while keeping the same satisfying metal feel. Stick with Level 1-2 puzzles to build confidence before moving higher.
Which Cast Puzzle Should You Buy Next After Solving the Diamond?
You cracked the Diamond—congratulations! Now you're probably wondering which puzzle to try next. The key is to stay in the same difficulty sweet spot: Level 1 or 2. The Cast Diamond is Hanayama's easiest, so jumping to a Level 6 would be frustrating. Instead, look for puzzles that teach you new mechanics (twisting, sliding, or rotating) without overwhelming you.
Below is a quick comparison of the most popular follow-up puzzles. Prices range from $12.77 to $25.99, and solve times vary from 30 seconds (Diamond) to about 5 minutes for a Level 2. Use this table to find your next satisfying challenge.
| Puzzle | Price | Difficulty (1-6) | Best For |
|---|
| Cast Diamond (reference) | $12–$15 | 1 | Absolute beginner |
| Cast Hook | $13.99 | 2 | First step up |
| Cast Keyhole | $14.99 | 2 | Same feel as Diamond |
| Cast Galaxy 4-Piece | $14.88 | 2 | Visual satisfaction |
| Cast Coil Triangle | $25.99 | 2 | Desk display piece |
| 5 Piece Cast Spiral | $16.99 | 2 | Sequential challenge |
Who should skip this tier? If you solved the Diamond in under 10 seconds and felt no resistance at all, you might want to skip Level 2 entirely. Consider jumping to a Level 3 or 4 puzzle like the Cast Vortex or Cast Equa. But for most first-timers, the puzzles above offer the perfect 'aha' moment without the 'uh-oh' frustration.
The Cast Diamond is rated Level 1 out of 6 by Hanayama, making it the easiest metal puzzle in their entire series. Over 2,000 5-star reviews call it 'oddly satisfying' and 'perfect for beginners.' With just two pieces that need to slide together at a specific angle, the average solve time for a first-timer is under 2 minutes.
You might be staring at those two metal halves and thinking, 'This looks harder than it should be.' That's exactly how I felt. But here's the truth: the Cast Diamond is Hanayama's Level 1—their easiest classification. In the Cast series, difficulty goes from 1 (easiest) to 6 (hardest). The Diamond sits at the very bottom of that scale.
What does Level 1 mean in practice? You don't need any tools, no twisting, no force. It's a straight two-piece slide that clicks together once you find the right 45-degree angle. I solved it in under 30 seconds on my first go, and I'm no puzzle prodigy. The puzzle is designed so that the motion feels intuitive once you stop forcing it.

You've mastered the Diamond—now it's time to level up your puzzle confidence without jumping into anything too brutal. The best next step is to try the Cast Hook (Level 2), which adds a subtle twist motion while keeping the same satisfying metal feel. Our Step-by-step Cast Hook solution makes it easy to follow.
After the Hook, try the 5 Piece Cast Spiral (Level 2) for a sequential disassembly challenge—it separates into five rings that must be aligned in order. For something with a different mechanism, consider the Cast Coil Triangle (Level 2), which requires you to release a wire from a coiled frame.
Once you're comfortable with Level 2, graduate to a Level 3 puzzle like the Cast Keyhole (see our How to solve the Cast Keyhole puzzle guide). After that, try a wooden Luban Lock for a completely different tactile experience. Remember, it's not about speed—it's about enjoying the 'click' and 'snap' of each solution.
