Treasure Hunt printable sheet
Printable grids

Can you find the hidden treasure?

The treasure has been hidden somewhere on this beach, where the grid lines intersect (cross).

Input coordinates to help find the treasure with the fewest guesses. The interactivity gives you the shortest distance you'd have to travel (along the grid lines) to reach the treasure.

Can you find a reliable strategy for choosing coordinates that will locate the treasure in the minimum number of guesses?
