What this puzzle is about
The Ocean Research Trip puts four crew members, Leo, Owen, Hugo, and June, aboard a research boat. Each used one tool (a compass, a sample jar, a camera, or a ruler) at one station: the bow, the lab, the cabin, or the deck. Five clues lead to one solution.
Who it suits
It is a hard 4 × 4 × 4 grid. Four clues are direct, and one links a tool to a station, which is the clue that ties the grids together. It suits solvers ready for a bigger board, science-minded kids who already have some logic grid experience, and anyone who wants a longer puzzle that still starts with a few easy footholds.
How to start
Mark Owen's two clues (the camera and the bow), Leo's compass, and Hugo in the cabin, clearing rows and columns after each ✓. Then write the ruler-and-lab link into the keepsakes-and-places grid and check which crew members are still free to have been working in the lab.
How to solve this puzzle
Each person has one keepsake and visited one place. A yes mark eliminates the other options in the same row and column. Combine the clues until all three grids agree.
