Coffee Roaster is a well-designed solo puzzle that does exactly what it sets out to do: give you a satisfying 20-minute brain workout wrapped in an oddly compelling coffee theme. The bag-building mechanism is clever, the push-your-luck decisions are meaningful, and the 22 bean varieties provide enough variety to keep you coming back.

But let's be clear about what this is: it's a solo optimization puzzle with a niche theme. If your kid isn't into strategic puzzles or doesn't find coffee roasting remotely interesting, this will gather dust. It's not family game night material, it's not wildly imaginative, and it won't teach life lessons beyond 'sometimes probability screws you.'

For the right player—someone who enjoys solo gaming, appreciates clever mechanisms, and likes chasing high scores through iterative improvement—this is a solid 81. For everyone else, it's a curiosity at best.
