From the IB:

"For each given tile in the inventory, find the location of the exact design of that tile within a square piece on the grid, and scribble out the remaining bits inside that piece. The design must be a perfect match in size and color. It may appear rotated, but it is not turned over. One sample tile has already been located. When all tiles are completed, a coherent image will appear.

Small errors that would not interfere with the design are permissible if this is rare on the grid. Larger omissions, clear mistakes, and inadequate shading result in penalties. Teams are eligible for full marks and bonus if there are at most two incorrect pieces in their solution (60%).

Partial credit is only given by how much a team completes the borders successively, advancing towards the center. Completing all the squares along the border is worth 25% of the score (maximum of one error). Completing all the squares along the border twice over (i.e., two squares deep) is worth 50% of the score (maximum of one error). There is no other partial credit."
